摘要
采用一种简单的方法合成了具有{001}和{110}共露刻面以及氧空位的单晶 BiOCl 纳米片。这些纳米片具有活化分子氧的能力，在太阳光照射下可产生活性超氧自由基（77.8%）和单线态氧（22.2%）。在模拟太阳光下产生 H2O2，以及在蓝色 LED 光下氧化羟基苯硼酸，BiOCl 都表现出卓越的光催化效率。我们的研究强调了构建共暴露的{001}和{110}面以及氧空位对提高光催化性能的重要意义。BiOCl 纳米片能够产生 H2O2，太阳能到化学能的转换效率为 0.11%。
Solar Light-Driven Molecular Oxygen Activation by BiOCl Nanosheets: Synergy of Coexposed {001}, {110} Facets and Oxygen Vacancies.
Single-crystalline BiOCl nanosheets with coexposed {001} and {110} facets, as well as oxygen vacancies, were synthesized using a simple method. These nanosheets have the ability to activate molecular oxygen, producing reactive superoxide radicals (77.8%) and singlet oxygen (22.2%) when exposed to solar light. The BiOCl demonstrated excellent photocatalytic efficiency in producing H2O2 under simulated solar light and in oxidatively hydroxylating phenylboronic acid under blue LED light. Our research highlights the significance of constructing coexposed {001} and {110} facets, as well as oxygen vacancies, in enhancing photocatalytic performance. The BiOCl nanosheets have the capability to produce H2O2 with a solar-to-chemical energy conversion efficiency of 0.11%.
