Effects of anatase TiO2 with different particle sizes and contents on the stability of supported Pt catalysts

► Pt is deposited on the mixed support of TiO2 and carbon black by the microwave-assisted polyol process. ► TiO2 with different particle sizes and contents may evidently influence the stability of Pt/TiO2-C. ► The optimized particle size of TiO2 is 20 nm and 40% TiO2 existed in the mixed support is the optimized TiO2 content.
