摘要:

随着全球能源危机与环境污染问题的日益加剧, 开发高效、绿色、可持续的能源转化与污染治理技术成为当今科学研究的重要方向. 光催化技术因其能够直接利用太阳能驱动氧化还原反应, 在清洁能源生产与环境修复领域展现出巨大潜力. 其中, 一维(1D)纳米材料(如纳米棒、纳米线、纳米纤维、纳米管和纳米带)因具有优异的电荷定向传输通道、高比表面积以及丰富的表面活性位点, 成为光催化领域的研究热点. 然而, 单一的1D材料存在光生载流子复合快、量子效率低等问题, 限制了其实际应用. 因此, 构建具有高效电荷分离能力的异质结体系成为提高其光催化性能的关键途径, 特别是近年来提出的S型异质结在促进光生载流子定向迁移与保持强氧化还原能力方面表现突出, 为光催化性能提升提供了新的思路.
本文系统综述了1D S型异质结光催化材料的最新研究进展, 重点介绍了其设计理念、构建方法、表征技术以及应用表现. 首先, 从S型电荷转移模型的历史演变与机理出发, 明确了其在维持强氧化还原能力的同时实现高效载流子分离的本质机理. 随后, 系统总结了1D S型异质结的主要构建方法, 包括原位生长法和静电自组装法. 原位生长法通过水热、溶剂热或煅烧过程在一维骨架表面沉积第二组分, 能够形成紧密接触界面; 静电自组装法则利用组分间正负电荷的库仑作用构建复合界面, 适用于形貌复杂的多组分体系. 还介绍了S型异质结的关键表征方法, 如原位X-射线光电子能谱、开尔文探针力显微镜表面电势测定和飞秒瞬态吸收光谱, 这些技术从电子迁移、能带弯曲和载流子寿命等角度验证了S型电荷转移机制的合理性. 此外, 进一步比较了0D/1D, 1D/1D,1D/2D和1D/3D等多种异质结构体系的性能差异, 指出0D/1D与1D/2D结构在界面耦合、载流子分离与光吸收协同方面最具优势. 典型体系如TiO2/Ce2S3, Cu2O/W18O49和Ag2S/Ta2O5等实现了CO2光还原、产氢、H2O2生成与有机污染物降解等多功能应用. 研究结果表明, 1D S型异质结通过构筑长程电荷迁移通道与高效界面电场, 可显著提高光生载流子的寿命与迁移速率, 实现优异的能量转换与环境净化性能.
最后, 本文展望了1D S型异质结光催化剂未来的发展方向: (1)拓展新型1D结构体系(如含铋纳米线、MOF/COF纳米纤维等); (2)通过晶面调控提升电荷传输效率; (3)结合原位表征与理论计算深入揭示电荷迁移机理; (4)强化半导体界面化学耦合, 构建高效稳定的异质结体系, 以推动其在能源转化与环境修复中的实际应用. 总体而言, 1D S型异质结的研究为解决能源与环境问题提供了新的材料体系与理论基础, 对推动光催化技术的持续发展具有重要意义.

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.
