摘　　要：Photocatalytic water splitting for hydrogen evolution is one of the most promising approaches to address energy and environmental issues [1-4]. Metal-free photo- catalysts, usually containing low cost and earth-abundant C, N and O elements, are more advantageous than the traditional metal-based photocatalysts and have attracted considerable interest for many years [5-10].氢能源是未来最理想的清洁能源,可以利用太阳能和光催化材料分解水获得.开发廉价、资源丰富、环境友好的光催化材料,成为近年来能源和环境领域的研究热点.基于此,我们报道了一种新型有机光催化材料-不含金属的荧光素超分子纳米片,其在可见光下显示出高效的光催化分解水产氢活性,产氢速率接近341μmol g^(-1)h^(-1),在420±10 nm的波段下表观量子效率达到1.2%.这是荧光素超分子晶体首次被报道并应用于可见光下分解水产氢,这一发现丰富了有机和超分子光催化剂的种类.
