The structure and electronic state of the active center in a single-atom catalyst undergo noticeable changes during dynamic catalytic process. metal atom is not well demonstrated manner. This study that Li atoms, serving as centers, can migrate on C3N4 monolayer or between monolayers when exposed to light irradiation. migration alters local coordination environment nanosheets, leading significant enhancement photocatalytic activity. H2O2 process could be maintained for 35 h with 920 mmol/g record-high yield, corresponding 0.4% concentration, which far greater than value (0.1%) practical application wastewater treatment. Density functional theory calculations indicated Li-coordinated structures contributed superhigh

In the past decade, isolated single atoms have been successfully dispersed on various substrates, with their potential applications being intensively investigated in different reactions. While essential target of research single-atom catalysis is precise synthesis stable catalysts (SACs) clear configurations and impressive catalytic performance, theoretical investigations also played important roles identifying active sites, revealing mechanisms, establishing structure–activity relationships. Nevertheless, special attention should still be paid works to particularity SACs. this Perspective, we will summarize progress made understanding rich phenomena catalysis. We focus determination local structures SACs via comparison between experiments simulations, discovery distinctive mechanisms induced by multiadsorption, synergetic effects, dynamic evolutions, name a few, proposal criteria for theoretically designing SACs, extension original concepts hope that Perspective inspire more in-depth thinking future studies
