energy band modulation and heterojunction formation can markedly improve PEC performance and solar conversion. In this context, this review begins with a description of the PEC water oxidation mechanism, efficiency-related parameters, band bending and charge transfer behavior within n-type SC photoanodes, followed by an overview of recent progress and our contributions in fabricating efficient TMD-based heterostructure photoanodes with various synthetic routes and architectures. Next, the unique superiorities and positive effects of TMD utilization, such as optimized light harvesting, regulated electron transfer channels, promoted charge separation and transport, and improved long-term photostability, were comprehensively summarized in various TMD/SC heterostructure photoanode systems. Finally, the remaining challenges and future opportunities in advancing TMD-based van der Waals heterostructure photoanodes for next generation PEC water splitting applications are addressed.
