Pt support of multidimensional active sites and radial channels formed by SnO2 flower-like crystals for methanol and ethanol oxidation

▶ The SnO2 nanoflowers are employed to obtain multidimensional Pt/SnO2 catalysts. ▶ The catalyst of multidimensional active sites and radial channels is used for alcohol oxidation. ▶ The catalyst shows higher electrocatalytic activity and better long-term cycle stability.
