Highly Active Sites in Quaternary LnPdAsO (Ln = La, Ce, Pr) with Excellent Catalytic Activity for Hydrogen Evolution Reaction

We report the catalytic activity in LnPdAsO (Ln = La, Ce, Pr). In this PdAs– layer (II), by elongating the distance of Pd–Pd, the overpotentials toward HER are 110.0, 89.5, and 62.0 mV at 10 mA/cm2...
