Abstract

Halide perovskites have gained significant attention in the field of photovoltaics and photocatalysis due to their exceptional optoelectronic properties. However, the exploration of other classes of 2D perovskite materials is limited. In this work, the photocatalytic performance of (HA)PbX4 2D crystals embedded with MoS2 in their bulk structure is investigated. The (HA)PbX4@MoS2 composites are directly synthesized in a (HA)PbX4 crystal solution. Notably, the (HA)PbI4@MoS2 composite exhibits a remarkable 2.94‐fold increase in H2 evolution activity. Furthermore, the composite demonstrated stability in a (HA)PbX4 (HA = histamine, X = I, Br, Cl)‐saturated aqueous HX solution. The photogenerated electrons in (HA)PbX4 are efficiently transferred to the MoS2 sites, facilitating the reduction of protons to H2. In this study, the potential of hybrid 2D perovskite–MoS2 composites is highlighted as promising visible‐light photocatalysts for aqueous solution applications.
