As a promising non‐precious metal photoelectrochemical (PEC) catalyst, MoS₂ exhibits high electrocatalytic activity and stability, while the weak light absorption efficiency and low photoresponse current limit its practical application. Herein, a facile co‐assembly approach is proposed to construct porphyrin‐MoS₂ composite photoelectrocatalysts. The as‐prepared photoelectrocatalysts show a significantly enhanced photocurrent response as high as 16 μA cm⁻², which is about 2 times higher than that of bare MoS₂. Furthermore, the obtained porphyrin‐MoS₂ catalysts exhibit excellent durability when tested for 23000 s, thus providing a useful strategy for the design of highly efficient dye‐sensitized PEC catalysts.

卟啉-MoS2复合纳米片的受控组装可增强光电化学性能

作为有前途的非贵金属光电化学催化剂，MoS ₂具有较高的电催化活性和稳定性，而光吸收效率低和光响应电流低限制了其实际应用。本文提出了一种简便的共组装方法来构建卟啉-MoS ₂复合光电催化剂。所制备的光催化剂显示出显着增强的光电流响应，高达16μAcm ^-2，是裸MoS _2的2倍左右。此外，所获得的卟啉-MoS ₂催化剂经过23000 s的测试显示出优异的耐久性，因此为设计高效染料敏化的PEC催化剂提供了有用的策略。
