Abstract

How to realize the efficient utilization of the solar energy and the separation capacity of photo-generated charges is an instant problem in the field of photocatalytic degradation utilizing bismuth oxyhalide. Here, Bi/BiOBr-Bi₄O₅I₂ (BOB-BI) heterojunctions have been successfully designed and constructed. The optimized 1BOB-1BI heterojunction achieves a 100 % degradation rate of BPA under simulated solar light illumination (25 min). This excellent photocatalytic ability is ascribable to the synergistic effect of Bi particles and the formation of heterojunction. The significantly improved light absorption of the photocatalyst was benefited by the localized surface plasmon resonance (LSPR) effect of Bi particles. The construction of the heterojunction effectively reduces the interfacial transfer resistance, enhancing the separation capacity of photo-generated charges. This research provides a deep insight to the construction of effective bismuth-based heterojunction photocatalysts.

构建Bi/ bibr - bi4o5i2异质结增强光吸收和电荷分离，高效降解双酚A

如何实现太阳能的高效利用和光生电荷的分离能力，是利用氧化卤化铋光催化降解领域亟待解决的问题。本文成功地设计和构建了Bi/ bibr - bi4o5i2 （BOB-BI）异质结。优化后的1BOB-1BI异质结在模拟太阳光照（25 min）下实现了100%的BPA降解率。这种优异的光催化能力归因于Bi粒子的协同作用和异质结的形成。铋粒子的局部表面等离子体共振（LSPR）效应显著改善了光催化剂的光吸收。异质结的构建有效地降低了界面转移阻力，增强了光生电荷的分离能力。本研究为构建有效的铋基异质结光催化剂提供了深入的见解。
