Electrocatalytic Reduction Catalysts: Hollow Mesoporous Carbon Sphere Loaded Ni–N 4 Single‐Atom: Support Structure Study for CO 2 Electrocatalytic Reduction Catalyst (Small 41/2020)

In article number 2003943, Hongfang Li, Rong Cao, and co-workers successfully synthesize a hollow mesoporous carbon sphere loaded Ni–N4 single-atom catalyst that exhibits superior catalytic activity toward CO2 electrocatalytic reduction. The geometrical structure of carbon support is verified to affect the CO2 reduction reaction performance greatly. The ultrathin carbon shell and the 7–10 nm mesopores of the hollow mesoporous carbon spheres facilitate the CO2 molecule activation.
