Collaboratively boosting charge transfer and CO2 chemisorption of SnO2 to selectively reduce CO2 to HCOOH

We have developed a SnO x -based CO 2 RR electrocatalyst (SnO 2 -V O @N–C), which combine the oxygen vacancies and coating with N-doped carbon layers. The obtained SnO 2 -V O @N–C showed highly-enhanced catalytic activity and selectivity for HCOOH.
