          Bi系光催化材料是近年來被廣泛研究的一類新型光催化劑,具有獨特的層狀結構和合適的帶隙,價導帶位置可調,是一類性能優異、環境友好型、結構可調的光催化劑,在環境與能源領域具有廣闊的應用前景。本文介紹了Bi系光催化材料的種類,系統綜述了形貌調控、表面缺陷引入、晶面構建、表面等離子體修飾、元素摻雜、構建異質結等結構調控方法,分析了光催化性能增強作用機制,并重點總結了鉍系光催化材料在水處理、空氣凈化、固氮、產氫等環境凈化和能源轉化領域的應用研究進展,最后討論了該領域所面臨的挑戰,并對Bi系光催化材料未來的發展進行了展望。

          Abstract:

          Bismuth based photocatalytic material,with the unique layered structure,suitable bandgap,and adjustable valence and conduction band position,is a new kind of unique photocatalysis material developed in recent years. Because of its high efficiency,innocuity,controllable morphology,it has a wide application prospect in the fields of solar energy conversion and environmental remediation. In this paper,the types of Bi based photocatalytic materials are introduced. The structural control methods such as morphology control and surface defect introduction,crystal face construction,surface plasma modification,element doping and heterojunction construction are systematically reviewed. The enhancing mechanism of photocatalytic performance is analyzed,and the application of Bi based photocatalytic materials in water treatment,air purification,nitrogen fixation and hydrogen production are summarized. Finally,the challenges in this field are discussed,and the future development of Bi based photocatalytic materials is prospected.
