摘要
黑磷具有厚度依赖的直接带隙、宽的光谱吸收范围、高的载流子迁移速率、高的比表面积以及表面丰富的催化活性位点等诸多优点,是一种极具发展潜力的光催化分解水产氢的二维半导体材料。但其产氢效率有限,通过对黑磷改性是提高其光催化性能的重要方法。归纳了黑磷的结构和形貌控制、负载助催化剂和构筑异质结体系等改性策略,介绍了黑磷改性材料在光催化水产氢领域的最新研究进展,并对其存在的问题作出展望。
Black phosphorus has many advantages,such as thickness dependent direct band gap,wide spectral absorption range,high carrier migration rate,high specific surface area and abundant catalytic active sites on the surface.It is a two-dimensional semiconductor material with great development potential for photocatalytic decomposition of aquatic hydrogen.However,its hydrogen production efficiency is limited.The modification of black phosphorus is an important method to improve its photocatalytic performance.The modification strategies of black phosphorus,such as structure and morphology control,supported cocatalysts and heterojunction system are summarized.The latest research progress of black phosphorus modified materials in the field of photocatalytic aquatic hydrogen is introduced,and some existing problems are prospected.
