The synergy of modulated surface polarity and oxygen vacancy for CO_(2) to methanol over Zn(δ-)-Ti(δ+)Ovacancy

Bi-functional catalysts,which can be traced back to 1960s,are widely applied in energy conversion and chemical transformation[1].Generally,the enhanced performance of the bi-functional catalyst comes from the local geometry or electron density change after the second component introduced.These changes facilitate the reaction at the structure or electron density level[2].In fact,it is a great challenge to understand and control those effects[3].
