Hetero-element doping is one of the most effective methods for band gap regulation of semiconductor photocatalysts. Here, a novel layer of stacked iodine and phosphorus co-doped carbon nitride (I/P-CN) was prepared. The obtained I/P-CN exhibited significantly enhanced visible-light photocatalytic hydrogen production compared with bulk carbon nitride.

层堆叠碘和磷共掺杂的C3N4用于增强可见光光催化氢的释放

杂元素掺杂是调节半导体光催化剂的带隙的最有效方法之一。在这里，制备了堆叠的碘和磷共掺杂的氮化碳（I / P-CN）的新型层。与本体氮化碳相比，所获得的I / P-CN显示出显着增强的可见光光催化氢产生。
