Synthesis and performance of Pd/SnO2-TiO2/MWCNT catalysts for direct formic acid fuel cell application

► Pd based on the SnO2-TiO2 precursor anchored on MWCNTs synthesized for DFAFCs. ► Uniform dispersion of the Pd particles attributed to the addition of the Sn (II). ► Introduction of the Sn has promoting effect on catalyst activity and CO tolerance. ► The synthesized catalyst exhibits excellent performance for formic acid oxidation.
