Bi_(2)MoO_(6)光催化剂调控技术及其研究进展

Regulation technology and research progress of Bi_(2)MoO_(6) photocatalyst

高活性的光催化剂对可再生能源的替代和环境保护至关重要。Bi_(2)MoO_(6)作为一种Aurivillius结构材料,因其可见光吸收、无毒、成本低、化学耐久性好,一直是光催化应用的热点。但纯Bi_(2)MoO_(6)分离光生载流子效率低,比表面积小,量子产率差,导致光催化活性低。为了提高Bi_(2)MoO_(6)的光催化活性,人们已经系统地探索了各种方法,如形貌控制、掺杂/缺陷引入、金属沉积、半导体结合、共轭结构表面修饰等,取得了一定的成果。

Highly active photocatalysts driving chemical reactions are of paramount importance toward renewable energy substitutes and environmental protection.As a fascinating Aurivillius phase material,Bi_(2)MoO_(6) has been the hotspot in photocatalytic applications due to its visible light absorption,nontoxicity,low cost,and high chemical durability.However,pure Bi_(2)MoO_(6) suffers from low efficiency in separating photogenerated carriers,small surface area and poor quantum yield,resulting in low photocatalytic activity.Various strategies,such as morphology control,doping/defect-introduction,metal deposition,semiconductor combination and surface modification with conjugativeπstructures,have been systematically explored to improve the photocatalytic activity of Bi_(2)MoO_(6).
