Asymmetrical Sc coordination-induced bridging structure and surface relaxation for boosting H2O2 photoactivation in Fenton-like catalysis

A single-atom of the transition metal scandium is introduced into the g-C 3 N 4 /MoSe 2 heterojunction interfaces to form a single-atom bridging structure (Se–Sc–N) for H 2 O 2 activation in a photo-Fenton-like system.
