Supported metal catalysts have been widely applied and commonly fabricated through the H2 reduction process. Herein, we develop a H2‐free room‐temperature discharge‐driven reduction (RT‐DR) reactor for fabricating supported metal catalysts at room temperature without H2. By RT‐DR reactor, a catalyst with pseudo‐boehmite (PB) as support (CdS/Pt/PB) is fabricated. In visible‐light‐driven photocatalytic H2O splitting to H2, CdS/Pt/PB shows a H2 evolution rate of 1132 μmol h−1, which is greatly enhanced than that on catalyst prepared by traditional H2‐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 H2O splitting to H2, CdS/Pt/LSPB shows a H2 evolution rate of 2554 μmol h−1, which is 2.5 times higher than that on catalyst prepared by traditional H2‐reduction (1029 μmol h−1). Thus, RT‐DR reactor has high efficiency and universality in preparing catalysts, thus offering a great potential for commercialization.

放电反应器，用于在室温下在没有 H2 的情况下制造高效的负载型金属催化剂


负载型金属催化剂已得到广泛应用，通常通过 H2 还原工艺制造。在此，我们开发了一种无 H2 室温放电驱动还原 （RT-DR） 反应器，用于在室温下制造负载型金属催化剂，无需 H2。通过 RT-DR 反应器，制备了以准勃姆石 （PB） 为载体 （CdS/Pt/PB） 的催化剂。在可见光驱动的光催化 H 2 O 分裂成 H 2 中，CdS/Pt/PB 显示 H 2 析出速率为 1132 μmol h -1 ，这比传统 H 2 还原制备的催化剂 （633 μmol h -1） 大大增强。RT-DR 反应器还用于制备以低钠 PB （LSPB） 为载体 （CdS/Pt/LSPB） 的催化剂。在可见光驱动的光催化 H 2 O 分裂成 H 2 中，CdS/Pt/LSPB 显示 H 2 释放速率为 2554 μmol h-1，比传统 H2 还原制备的催化剂 （1029 μmol h-1） 高 2.5 倍。因此，RT-DR 反应器在制备催化剂方面具有很高的效率和通用性，因此具有很大的商业化潜力。
