identification of small organohalide molecules as halide sources. When these precursors are spatially and temporally confined in the aerosol phase with molten salt fluxes, powders composed of single-crystalline BiOX nanoplates can be produced continuously. A mechanism highlighting the in situ generation of halide ions is proposed. These materials can be used as photocatalysts and provide proof-of-concept toward
金属杂阴离子材料,例如卤氧化物,是有前途的光催化剂,其中可以通过改变卤化物的身份来设计能带位置以吸收可见光。为了促进这些材料的合成,已经使用快速且可扩展的超声喷雾合成法(USS)制备了BiOX形式的卤氧化铋(X = Cl,Br)。这一进展的中心是确定小的有机卤化物分子为卤化物源。当这些前体在空间和时间上被熔融盐熔剂限制在气溶胶相中时,可以连续生产由单晶BiOX纳米板组成的粉末。提出了突出卤离子原位产生的机理。
