A defect engineered p-block SnS2−xcatalyst for efficient electrocatalytic NO reduction to NH3

Defect-engineered SnS 2− x has been demonstrated for the first time as an efficient p-block catalyst for electrocatalytic NO reduction to NH 3 (NORR), attributed to the active Sn-V S sites that selectively activate NO and reduce the energy barriers of the NORR pathway.
