Different　preparation　routes　for　TiO2-supported　natural　and　synthetic　clinoptilolite　(TiO2/CP)　composites　were　thoroughly　investigated　on　the　basis　of　sol-gel,　hydrothermal,　and　in-situ　hydrothermal　methods.　The　micro-structural　features　and　physicochemical　properties　of　resultant　TiO2/CPs　were　characterized　via　X-ray　diffraction　patterns,　scanning　(transmission)　electron　microscope　images,　Fourier　transform　infrared　spectra,　inductively　coupled　plasma-optical　emission　spectrometry　methods,　BET-isotherms,　UV-visible　spectra,　and　surface　charge　potential　distributions.　The　results　showed　that　in-situ　hydrothermal　method　led　to　well　dispersions　of　loaded-TiO(2　)particles　on　the　surface　of　leaf-like　CP,　while　obviously　aggregated　TiO(2　)on　a　relatively　distorted　structure　of　CP　was　obtained　using　sol-gel　and　hydrothermal　methods.　Their　adsorptive　and　photocatalytic　efficiencies　for　removal　of　crystal　violet　(CV)　dye　in　aqueous　solution　were　also　explored　under　UV-irradiations.　The　results　demonstrated　that　TiO2/CPs　synthesized　via　sol-gel　and　in-situ　hydrothermal　methods　presented　the　excellent　performances　with　98%　removal　efficiencies　as　compare　to　the　bare　commercial　TiO2　which　achieved　53%　removal　of　CV　dye.　While,　the　in-situ　hydrothermally　synthesized　TiO2/CPs　were　the　best　due　to　their　moderate　energy　cost,　highest　adsorption　capacities　and　removal　efficiencies.　Particularly,　the　synthetic　CPs　as　supports　exhibited　synergetic　photocatalytic　activities　for　the　degradation　of　CV　dye,　which　is　attributed　to　their　high　surface　areas,　better　adsorption　capability,　and　fine　dispersion　of　TiO2　particles.　Adsorption　and　degradation　kinetics　of　CV　dye　were　found　to　follow　the　pseudo-second　and　pseudo-first　order　models,　respectively.　(C)　2020　The　Chemical　Industry　and　Engineering　Society　of　China,　and　Chemical　Industry　Press　Co.,　Ltd.　All　rights　reserved.
