Isolated single-atom platinum (Pt) embedded in the sub-nanoporosity of 2D g-C3 N4 as a new form of co-catalyst is reported. The highly stable single-atom co-catalyst maximizes the atom efficiency and alters the surface trap states of g-C3 N4 , leading to significantly enhanced photocatalytic H2 evolution activity, 8.6 times higher than that of Pt nanoparticles and up to 50 times that for bare g-C3 N4 .
报道了一种新型共催化剂，即将孤立的单原子铂（Pt）嵌入二维 g-C3 N4 的亚纳米孔隙中。这种高度稳定的单原子共催化剂最大限度地提高了原子效率，并改变了 g-C3 N4 的表面陷阱态，从而显著提高了光催化 H2 释放活性，比 Pt 纳米颗粒高 8.6 倍，比裸 g-C3 N4 高 50 倍。
