Abstract
Reinforcing the carrier separation is the key issue to maximize the photocatalytic hydrogen evolution (PHE) efficiency of graphitic carbon nitride (g-C N ). By a surface engineering of gradual doping of graphited carbon rings within g-C N , suitable energy band structures and built-in electric fields are established. Photoinduced electrons and holes are impelled into diverse directions, leading to a 21-fold improvement in the PHE rate.
摘要
强化载体分离是最大限度提高石墨相氮化碳(g-CN)光催化制氢(PHE)效率的关键问题。通过在 g-CN 内逐渐掺杂石墨化碳环的表面工程，建立了合适的能带结构和内置电场。光生电子和空穴被推向不同的方向，从而使 PHE 速率提高了 21 倍。
