Research progress in graphene based single atom catalysts in recent years

Transition metal (Ti, Cu, Zn, Pt) single-atom modified graphene/AS2 (A = Mo, W) van der Waals heterostructures for removing airborne pollutants

“…39 Specifically, graphene has a high surface area and properties that makes it suitable as a substrate for SACs. 40 The dopant can act in two ways: promoting the catalytic activity of neighboring carbon atoms by donating or withdrawing electrons or stabilizing graphene, where the dopant atom itself is the active site for a target catalytic reaction. 41 In this sense, Mollaamin et al , in 2023, 42 reported the NO 2 and CO 2 adsorption on Mn, Fe, Co, Ni, Cu, and Zn doped graphene, finding that the adsorption of the molecules is improved depending on the charge transfer between the substrate, where Co, Ni, Cu, and Zn are promising gas sensors.…”
