摘要:

作为一种清洁的太阳能转换技术,半导体光催化为应对世界能源危机和环境污染治理提供了重要技术途径。而在不同类型的光催化剂中,铋基材料凭借其特有的晶体结构、可调的能带宽度、多样的化学组成,以及在光催化领域所具有的广泛前景而备受关注。尽管如此,当前关于铋基光催化剂的开发还不够完善,仍需要大量研究和讨论。为了提高铋基材料的催化性能,并克服目前低光利用效率、选择性差和成本高的挑战,对其结构、合成和结构调控方法的全面理解必不可少。因此本文系统论述了在太阳能应用领域,铋基光催化剂的合理设计与最新进展。这篇文章首先概述了多种铋基光催化剂的近期科研动态,包括层状铋化合物、铋元素、BiVO4、Bi2S2和Bi2O3等材料。其次,归纳了铋基光催化剂的主要合成方案,并介绍了提高催化活性的结构调控方法。接着,强调了铋基材料在CO2还原、光解水、N2固定、NOX去除、H2O2生产以及选择性有机反应等多种领域潜力巨大。此外,文章还深入探讨了用于铋基光催化剂的先进原位分析手段。最后,本综述明确了现存的发展障碍,并预测了铋基光催化剂的未来发展前景。本综述有望为深入理解和合理设计高性能铋基材料提供全面指导,推动环境与能源领域的创新应用,助力实现双碳目标和可持续发展。

Abstract:

Semiconductor photocatalysis makes full use of solar energy, serving as a potent tactic to solve the worldwide energy deficit and safeguard the environment. Bismuth-based photocatalysts stand out among various photocatalysts as a significant area, due to their unique crystal structure, favorable mixed electron band structure, diverse composition, and huge potential for solar catalytic conversion. This document reviews the rational design of Bi-based photocatalysts for solar energy. Recent advancements in diverse Bi-based photocatalysts such as Layered Bi, Bismuth element, BiVO4, Bi2S2, and Bi2O3 are highlighted. Secondly, the synthesis strategies of Bi-based catalysts, including hydrothermal/solvothermal, chemical precipitation, and solid-state reaction, are summarized. Third, various structural regulation methods to improve the photocatalytic performance, including defect regulation, heteroatom doping, morphology, SPR effect utilization, and heterojunction construction, are systematically introduced. Additionally, a focus is given to the exclusive applications of Bi-based photocatalysts, including CO2 reduction, water decomposition, N2 fixation, NOx removal, H2O2 production, and selective organic synthesis, followed by an introduction of advanced in situ characterization techniques of the Bi-based photocatalysts. Ultimately, the forthcoming obstacles are underscored, and a future outlook for Bi-based photocatalysts is anticipated. This review aims to offer detailed instructions for comprehensively understanding and logically crafting effective bismuth-based photocatalysts, while also encouraging novel ideas and advances in energy and environmental fields, contributing to the goals of green chemistry and sustainable development.
