Abstract:

Photocatalysis provides a viable approach to address critical global challenges of energy scarcity and environmental pollution. Significantly, one-dimensional (1D) nanomaterials (e.g., nanorods, nanowires, nanofibers, nanotubes, and nanobelts) have attracted great attention in the field of photocatalysis owing to their inherent structural advantages such as directional charge transport pathways, high aspect ratio, and abundant exposed active surface sites. Nevertheless, the inherent issue including rapid photogenerated carrier recombination and low apparent quantum efficiency continue to hinder practical implementation of 1D scaffolds. To overcome these limitations, step-scheme (S-scheme) heterojunctions have been strategically constructed using 1D nanomaterials as fundamental building blocks, demonstrating superior charge separation and enhanced photocatalytic properties. In this review, we comprehensively summarized recent advances in the design and implementation of 1D-based S-scheme photocatalysts for targeted applications in sustainable energy conversion, and environmental remediation. The review was introduced by a historical development of the S-scheme charge transfer model and the typical charge transfer mechanism, followed by a comprehensive summary of the preparation approaches and characterization techniques of 1D-based S-scheme systems. Subsequently, a detailed discussion of the recent advances in 1D S-scheme heterojunction photocatalysts for various applications are provided and the implications of the S-scheme charge transfer mechanism on promoting the catalytic activity are elucidated. Finally, the prospects for the development of 1D-based S-scheme heterojunction photocatalysts are presented.
