Abstract:Encapsulating 3d transition metals (3d TMs) in crystalline carbon is a crucial strategy for improving the activity and durability. However, it is unclear whether covering amorphous carbon can enhance catalytic activity and what the optimal thickness is. Herein, we precisely control the amorphous carbon thickness on 3d TMs. As the thickness of amorphous carbon increases, the catalytic activity of 3d TMs exhibits a volcano-type trend. Covering amorphous carbon with a thickness of ≤4−8 Å can simultaneously improv… Show more
