Tin oxide (SnO 2 ) electrocatalytic materials have the advantages of low cost and low toxicity, and the electrocatalytic reduction of CO 2 to formic acid is highly selective. In this paper, Pd-doped SnO 2 nanoparticle materials were synthesized by flame spray pyrolysis and their properties for electrocatalytic reduction of CO 2 to formic acid were explored in a gas diffusion electrolytic cell. The results showed that the Pd/SnO 2 catalysts could improve the catalytic activity for the conversion of CO 2 to formate, and the most superior 0.5 Pd/SnO 2 showed a Faraday efficiency of 63% for formate at -1.20 V vs. RHE and a current density of 90.59 mA.cm − 2 , which were 1.4 and 2.7 times higher than that of pure SnO 2 , respectively. The modified catalyst grains were refined, and the charge transfer resistance at the catalyst interface was reduced and the electrochemically active area was increased, generating more catalytically active sites and increasing the contact between CO 2 , electrolyte, and electrode-catalyst. Density-functional theory calculations showed that the doping of Pd element changed the local structure of SnO 2 , and the Pd/SnO 2 surface was more favorable for the generation of the intermediate products * HCOO − and formate as well as the inhibition of hydrogen precipitation, which was consistent with the experimental results.
