Platinum‐based catalysts occupy a pivotal position in diverse catalytic applications in hydrogen chemistry and electrochemistry, for instance, the hydrogen evolution reactions (HER). While adsorbed Pt atoms on supports often cause severe mismatching on electronic structures and HER behaviors from metallic Pt due to the different energy level distribution of electron orbitals. Here, the design of crystalline...
Electrocatalysts
In article number 2206368, Yi Wang, Li Qiu, Yang‐Gang Wang, Chong Cheng, and co‐workers report on engineering crystalline‐lattice‐confined atomic Pt in metal carbides, which exhibits near‐zero valence states, similar electronic structures, and matched hydrogen evolution behaviors as the Pt(111) surface. Remarkably, the Pt‐doped@WCx catalyst delivers 40 times greater mass activity...
