In　recent　years,　the　global　greenhouse　effect　has　been　receiving　more　and　more　attention　due　to　the　increasing　emission　of　greenhouse　gases.　CO2　and　CH4　have　been　widely　considered　as　the　main　greenhouse　gases　causing　global　warming　and　climate　change.　The　CO2　reforming　of　CH4　(CRM)　reaction　can　simultaneously　convert　both　CO2　and　CH4　into　value-added　synthesis　gas　(H-2　+　CO)　and　also　alleviate　the　emission　of　these　two　greenhouse　gases.　Ni-Based　catalysts　have　been　widely　investigated　as　the　most　promising　candidates　for　CRM　owing　to　their　advanced　activities　and　low　price.　However,　the　Ni-based　catalysts　usually　suffer　rapid　deactivation　due　to　the　thermal　sintering　of　metallic　Ni　active　sites　and　surface　carbon　deposition　during　the　CRM　reaction　at　high　temperatures　(＞640　degrees　C).　To　address　this　challenge,　researchers　worldwide　have　devoted　great　efforts　to　developing　highly　efficient　and　stable　Ni-based　catalysts.　However,　it　is　extremely　difficult　to　achieve　this　aim　by　using　the　traditional　supported　catalysts　because　of　the　weak　metal-support　interaction.　Therefore,　the　concept　of　Ni-based　confinement　catalysts,　such　as　core-shell　catalysts,　mesoporous　catalysts,　layered　catalysts,　and　Ni-containing　crystalline　compound　catalysts,　have　been　proposed　and　developed　to　address　the　challenge　of　the　thermal　sintering　of　the　metallic　Ni　active　sites　by　the　space　and/or　lattice　confinement　effects　of　these　structures.　As　a　result,　the　metallic　Ni　active　site　can　be　firmly　stabilized　and　the　surface　carbon　deposition　can　be　effectively　inhibited　owing　to　the　size　effect　of　the　metallic　Ni　active　sites.　This　review　mainly　summarizes　the　state-of-the-art　progress　of　the　Ni-based　confinement　catalysts　with　advanced　performances　for　CRM.　Specifically,　the　Ni-based　catalysts　with　different　confinement　types,　including　pore　channel　confinement,　core-shell　structure　confinement,　interlayer　structure　confinement,　and　crystalline　lattice　confinement,　have　been　summarized.　The　significant　impacts　of　the　confinement　effect　on　the　stabilization　of　the　Ni-based　CRM　catalysts　are　discussed　in　detail.　The　influences　of　the　preparation　methods　on　the　catalytic　performance　of　the　Ni-based　catalysts　are　also　discussed　and　their　development　trends　have　been　determined.
