Abstract ：
Single-atom catalysts (SACs), as a thriving subfield of catalysis, have progressed tremendously. However, the contradiction between the isolated dispersion feature of metal sites and the high mass-specific activity of the catalyst inhibits the advances of the SACs. Herein, the Pt atoms are confined at the metallic Co phase edge in two-dimensional Co/Co(OH)(2) hierarchy structure (Pt-SA-Co@Co-Co(OH)(2)) by the defect inducted order electrode-position strategy. Both integrations of in-situ/ex-situ experimental characterizations and theoretical calculation reveal that such metal edge confined Pt atoms possess an enlarged atom exposure ratio, high stability, and the like-metal electronic state contributed by metal Co 3d, which enables the Pt atoms with more suitable affinity to simultaneously bind the multiple H atoms for durable H*-H-2 conversion and H-2 evolution. Moreover, the metallic PtSA-Co collaborated Co/Co(OH)(2) interfaces demonstrate a strong H2O dissociation capacity by the preference adsorption of H* on metallic Pt-SA-Co and OH*on Co/Co(OH)(2) interfaces. Combining a further enhancement of constructing the catalysts on an Ag nanowire network to form a seamlessly conductive nanostructure, the Pt-SA-Co@Co-Co(OH)(2) achieves a high mass activity with 5.92 A mg(-1) at the overpotential of 100 mV in alkaline condition, 37 times to that of the benchmark Pt/C catalyst and significantly outperforming the reported catalysts. While our work has focused on the hydrogen evolution reaction, this class of metal edge collaborated single-atom catalysts may be conducive to unlock the low mass-specific activity of atomically dispersed catalysts for various processes, such as oxygen evolution reactions (OER), CO2 reduction, and biomass conversion, etc.

Abstract ：
Using the electrochemical technology to split water molecules to produce hydrogen is the key to obtain green hydrogen for solving the energy crisis. The large-scale application of hydrogen evolution reaction (HER) in water dissociation requires a highly active catalyst. In this paper, the highly dispersed PtCo bimetallic nanoparticles loading on MXene (PtCo/MXene) were prepared by using a step-to-step reduction strategy. The mentioned PtCo/MXene catalyst exhibits a high current density of -100 mA/cm2 in an acidic medium with just a 152 mV overpotential. In addition, the PtCo/MXene catalyst also displays a superior stability. Computational analysis and experimental testing demonstrate that the electronic interaction between Pt and Co can effectively modify the electronic structure of the active site, thereby enhancing the inherent catalytic performance of the material. More importantly, MXene two-dimensional nanosheets can expose more active sites because of their large specific surface area. Furthermore, MXene substrate with excellent electrical conductivity and harmonious interfaces between PtCo and MXene enhance charge transfer efficiency and lower the reaction activation energy.

Abstract ：
Electrochromic fabrics (ECFs) have demonstrated great potential in developing wearable products for applications in wearable displays and adaptive camouflage. Nonetheless, the lack of device integration usually makes ECFs not as flexible and lightweight as regular textiles. Herein, we developed a highly integrated all-in-one ECF by assembling all the essential components into a piece of nylon fabric. The configuration is based on EC-active polyaniline, Au reflector electrode and alumina counter electrode coating on both sides, and a gel electrolyte filling into the fabric. As a result, the all-in-one ECF has an ultrathin thickness of only 80 mu m, which offers flexibility superior to that of conventional ECFs. Stemming from the optical modulation between top PANI coating and a bottom Au reflector, the all-in-one ECF could deliver color switches between yellow and green, which are two typical environmental camouflage colors. It also demonstrates thermal management based on IR modulation behavior. Moreover, the dual-band optical modulation has excellent stability in response to mechanical bending, twisting, and tailoring. Considering excellent wearability and active optical modulation, the all-in-one ECF was further developed into an unmanned environmental adaptive camouflage prototype system by integrating with sensing and control modules, which exhibit fast color blending with dynamic environment background. The construction strategy of highly integrated ECFs proposed in this work could equally well apply to other EC-active materials and anticipated to provide new insights into developing high-performance intelligent applications, such as wearable displays and military camouflage clothing. The all-in-one ECF was exploited for an unmanned environment adaptive camouflage system.

Abstract ：
Multicolor electrochromics have emerged as a promising solution for achieving active color modulation akin to chameleon-like adaptive camouflage. However, the development of electrochromics with full-color tunability still remains challenging, given the weak molecular polarity of inherent active materials and the difficulty in forming polarizer orbitals under varying applied voltages. Employing molecular polarity adjustments, a novel electrochromic polymer is successfully developed with a donor-gradient design of molecular architecture, enabling comprehensive full-color tunability. The polymer demonstrates outstanding overall electrochromic performance, including fast switching (around 1.4 s), high coloration efficiency (395.1 cm2 C-1@550 nm) and excellent reversibility (over 92% retention after 5000 cycles). Leveraging the full-color tunability and rapid response, the electrochromic polymer is further integrated with sensing and control modules to create an environmental adaptive camouflage prototype system capable of seamlessly blending colors with dynamic background environments. This work is expected to provide a straightforward approach for developing full-color electrochromics for electrochromic camouflage applications. An electrochromic polymer with donor-gradient architecture covers the full-color gamut and enables full-color tunability. This is the first time to deeply explore the full-color electrochromic mechanism in this material system. Leveraging full-color tunability and rapid response, the electrochromic polymer is integrated with sensing and control modules to create an environmental adaptive camouflage prototype device, seamlessly blending colors with dynamic backgrounds. image

Abstract ：
Great progress has been made in the electrochromic (EC) technology with potential applications in various fields. As one of the most promising EC materials, Prussian blue (PB) has attracted great attention due to its excellent EC performance, such as low cost, easy synthesis, rich color states, chemical stability, suitable redox potential, and fast color-switching kinetics. This review summarizes the recent progress in PB electrodes and devices, including several typical preparation techniques of PB electrodes, as well as the recent key strategies for enhancing EC performance of PB electrodes. Specifically, PB-based electrochromic devices (ECDs) have been widely used in various fields, such as smart windows, electrochromic energy storage devices (EESDs), wearable electronics, smart displays, military camouflage, and other fields. Several opportunities and obstacles are suggested for advancing the development of PB-based ECDs. This comprehensive review is expected to offer valuable insights for the design and fabrication of sophisticated PB-based ECDs, enabling their practical integration into real-world applications.

Abstract ：
Designing low-content and high-activity Pt-based catalysts with the high durability for the electrochemical hydrogen production remains a challenge. In this study, a ternary metal phosphide (NiCoP) with 1D nanowire (NW) and 2D nanosheet (NS) morphologies incorporating Pt clusters (denoted as Pt cluster -NiCoP@NF NWs and Pt cluster - NiCoP@NF NSs, respectively) was prepared using a hydrothermal -phosphorization -electrodeposition method. Based on the "tip effect " of NWs and a high electrochemical surface area, the as-prepared Pt cluster - NiCoP@NF NWs display better hydrogen evolution reaction (HER) performance, with a low overpotential of 65 mV at a high current density of 100 mA cm -2 and a low Tafel slope of 38.86 mV dec -1 , than the Pt cluster - NiC - oP@NF NSs, with an overportential of 95 mV at 42.53 mV dec -1 . This indicates that the NiCoP NW-based support exhibits faster HER kinetics. The mass activity (11.47 A mgPt - 1 ) of the Pt cluster -NiCoP@NF NWs is higher than that of commercial Pt/C catalysts. Significantly, the Pt cluster -NiCoP@NF NWs display excellent cyclic stability with negligible losses for 5000 cycles and 30-h tests at a high current of 500 mA cm - 2 .
