As a promising non‐precious metal photoelectrochemical (PEC) catalyst, MoS 2 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‐MoS 2 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 MoS 2 . Furthermore, the obtained porphyrin‐MoS 2 catalysts exhibit excellent durability when tested for 23000 s, thus providing a useful strategy for the design of highly efficient dye‐sensitized PEC catalysts.
