Abstract Supported metal catalysts have been widely applied and commonly fabricated through the H 2 reduction process. Herein, we develop a H 2 ‐free room‐temperature discharge‐driven reduction (RT‐DR) reactor for fabricating supported metal catalysts at room temperature without H 2 . By RT‐DR reactor, a catalyst with pseudo‐boehmite (PB) as support (CdS/Pt/PB) is fabricated. In visible‐light‐driven photocatalytic H 2 O splitting to H 2 , CdS/Pt/PB shows a H 2 evolution rate of 1132 μmol h −1 , which is greatly enhanced than that on catalyst prepared by traditional H 2 ‐reduction (633 μmol h −1 ). RT‐DR reactor is also used to prepare a catalyst with low sodium PB (LSPB) as support (CdS/Pt/LSPB). In visible‐light‐driven photocatalytic H 2 O splitting to H 2 , CdS/Pt/LSPB shows a H 2 evolution rate of 2554 μmol h −1 , which is 2.5 times higher than that on catalyst prepared by traditional H 2 ‐reduction (1029 μmol h −1 ). Thus, RT‐DR reactor has high efficiency and universality in preparing catalysts, thus offering a great potential for commercialization.
