Abstract:

通过光催化来高效利用太阳能是解决环境问题和可持续发展未来的理想选择。BiOBr的半导体因其独特的窄带隙和层状结构，且具有优异的可见光吸收能力、低毒性和高光催化活性等优点，被广泛用作环境修复的光催化剂。正因为BiOBr的应用广泛且前景广阔，所以人们专注于对BiOBr的深入研究。本文综述了BiOBr基光催化剂在环境修复方面的最新发展及其制备与应用。重点介绍了控制产物形貌的合成策略，以及提高光催化活性的有效改性策略。其包括通过电荷分离增强本体相，增强空间电荷分离。本文还从污染物净化和二氧化碳减排两个方面综述了BiOBr基光催化剂在环境方面的应用。最后，讨论了BiOBr基材料在未来光催化研究中的挑战和机遇。
The efficient utilization of solar energy through photocatalysis is an ideal choice for solving environmental problems and sustainable development in the future. BioBr semiconductors are widely used as photocatalysts for environmental remediation because of their unique narrow band gap and layered structure, excellent visible light absorption ability, low toxicity and high photocatalytic activity. Because of the wide application and broad prospect of BioBr, people focus on the in-depth study of BioBr. This paper reviews the latest development, preparation and application of BioBr based photocatalysts in environmental remediation. The synthesis strategies to control the morphology of the products and the effective modification strategies to improve the photocatalytic activity were introduced. It includes enhancing the bulk phase and space charge separation through charge separation. This paper also summarizes the application of BioBr based photocatalyst in environment from two aspects: pollutant purification and carbon dioxide emission reduction. Finally, the challenges and opportunities of BioBr based materials in future photocatalytic research are discussed.
