摘要

快速工业化加剧了环境污染和能源危机,需要开发可持续的环境修复和清洁能源生产技术。在各种太阳能驱动的方法中,半导体辅助光催化已经成为一种绿色高效的污染物降解和能源生产方法。CuBi2O4是一种具有尖晶石结构和窄带隙(约1.5 ~ 1.8 eV)的p型半导体,由于其强可见光吸收、丰度和低毒性而显示出巨大的潜力。然而,它的光催化性能受到快速载流子重组和有限的氧化还原能力的阻碍。本文系统地探讨了CuBi2O4的结构和电子性能,以及各种制备方法。此外,本文还对元素掺杂和异质结工程等性能增强策略的最新进展进行了批判性分析,重点讨论了这些修饰如何影响载流子动力学、光收集和表面反应性。综上所述,本文综述了基于CuBi2O4的高效太阳能光催化剂的合理设计,旨在指导未来能源和环境应用的创新。

Emerging trends in photocatalytic energy and environmental applications of CuBi2O4: A review of improvement strategies
Rapid industrialization has exacerbated environmental pollution and energy crises, necessitating the development of sustainable technologies for environmental remediation and clean energy generation. Among various solar-driven approaches, semiconductor assisted photocatalysis has emerged as a green and efficient method for pollutant degradation and energy production. CuBi2O4, a p-type semiconductor with a spinel structure and a narrow bandgap (approximately 1.5–1.8 eV), has shown great potential due to its strong visible light absorption, abundance, and low toxicity. However, its photocatalytic performance is hindered by rapid charge carrier recombination and limited oxidation reduction capabilities. This review systematically explores the structural and electronic properties of CuBi2O4, along with various fabrication methods. Furthermore, recent advancements in performance enhancement strategies including elemental doping and heterojunction engineering are critically analysed, with an emphasis on how these modifications influence carrier dynamics, light harvesting, and surface reactivity. Overall, this review offers a comprehensive perspective on the rational design of CuBi2O4 based photocatalysts for efficient solar energy utilization, aiming to guide future innovations in energy and environmental applications.
