ABSTRACT
Defective sites promote the charge redistribution of CuPc, forming electron-rich region around Cu atoms through the electrons transfer from defects to CuPc. The high density of electrons makes the d-band center of Cu atoms close to the Fermi level and then reduces the energy barrier of the *OCHO intermediate, enhancing the HCOOH selectivity during CO2RR. -

ABSTRACT
In this work, pre-vacuum treatment on Mo2TiC2Tx removes the surficial terminal groups, meanwhile inducing surface oxidation defects, which alters the nucleation and growth of Ni NPs on the surface. Eventually, the hybrid electrocatalyst presents low overpotential and high durability over 75 hours HER in 1 M KOH solution.
