Silicon, a naturally abundant semiconductor , is an ideal material for photocatalytic hydrogen production. A class of highly crystalline mesoporous silicon spheres has been designed and synthesized that can exhibit prominent photocatalytic hydrogen production activity under visible light. The mesoporous silicon spheres exhibit high crystallinity, large surface area, narrow mesopore size distribution, and broadened band gap, leading to impressive photocatalytic hydrogen evolution performance.
