Cadmium　sulfide　has　attracted　wide　attention　in　photocatalytic　hydrogen　production,　due　to　its　appropriate　bandgap　and　band　positions.　However,　high-rate　photogenerated　electron-hole　recombination　and　few　active　sites　on　CdS　lead　to　its　low　photocatalytic　activity.　Herein,　a　PANI/NCPP/CdS　(PANI/NiCoP/NiCoPi/CdS)　hybrid　as　a　noble　metal-free　visible　light-driven　photocatalyst　is　reported,　with　metal　phosphides,　metal　phosphates,　and　polyaniline　(PANI)　as　reduction　and　oxidation　cocatalysts,　respectively.　This　hybrid　not　only　facilitates　the　charge　separation　and　transfer　owing　to　the　formation　of　heterojunction,　but　also　improves　the　local　concentration　of　H+　on　the　surface　of　catalysts　due　to　the　formation　of　the　protonated　amine　groups　on　PANI,　bene?cial　to　hydrogen　evolution　reaction.　As　a　result,　the　as-prepared　photocatalyst　could　show　a　high　hydrogen　evolution　rate　of　170.3　mmol　g(-1)　h(-1)　and　an　apparent　quantum　efficiency　of　41.37%　at　420　nm,　representing　one　of　the　best　performances　of　all-CdS-based　photocatalysts.
