摘要：We incorporated Cu into Bi nanocrystals to modulate the local electronic environment of Bi atoms, altering the HCOOH formation pathway from COOH* to OCHO* intermediates. Thus, the evolution of by-products CO and H-2 could be suppressed, and the resulting CuBi catalyst exhibits excellent CO2RR performance towards formate formation.
