Building Ultrathin MOL/MOL S‐Scheme Heterostructures toward Boosted Photocatalytic Charge Kinetics for Efficient H 2 Evolution

) with a high apparent quantum yield of 2.75% without additional cocatalysts, ranking among state-of-the-art activities from all-MOF photocatalysts. This work demonstrates an accessible and universal methodology to realize a superior ultrathin MOL/MOL heterojunction architecture toward accelerated charge kinetics, providing valuable insights for the development of efficient photocatalyst systems for solar-to-chemical energy conversions.
