ZIF‐67 Anchored Mn_0.5Cd_0.5S Constructs S‐Scheme Heterojunctions to Facilitate Photocatalytic Hydrogen Production

Solar RRL, Journal Year: 2025, Volume and Issue: unknown

Published: March 12, 2025

Photocatalytic hydrogen production is regarded as one of the most promising approaches for solar energy utilization due to its reliance on renewable sources, environmental friendliness, and generation clean energy. In this field, Mn 0.5 Cd S demonstrates considerable potential, but severe stacking issue insufficient exposure active sites restrict application. Although research, by combining with dodecahedral ZIF‐67 optimizing interfacial electronic structure, a uniform distribution surface was successfully accomplished. Synthesis composite materials effectively mitigated agglomeration phenomenon constructed an S‐scheme heterostructure S/ZIF‐67. The resulting achieved yield 677.4 μmol in lactic acid system, 6.8 times higher than that pure S. This notable enhancement attributed increased specific area composite, facilitating greater improving charge transfer efficiency. situ X‐ray photoelectron spectroscopy analysis revealed underlying electron mechanism, while EPR studies confirmed enhanced redox capacity further supporting superior performance production. research offers new insights into morphology interface engineering S‐based materials.
