Abstract
Establishment of heteroatoms-participantly coordinating single atom (SA) configuration is placed high expectation for exceptional catalytic property. Meanwhile, simple technologies to construct SA site with low cost had also been pursued in long-term. Herein, we introduced a facile complexing agent-assistant photodeposition strategy for SA Ag-N3S1 asymmetric site catalyst. The modification on substrate by heteroatom doping and the coexisting amine ligands’ complexation with silver cation are concurrently responsible for the construction of SA site. Attributed to modulation in electronic structure states, this Ag-N3S1 site-decorated carbon nitride exhibited extremely strengthened photocatalytic hydrogen production ability. This exploration provides a promising universal strategy for the establishment in SA catalysts of high-efficiency in broader field.
