摘要

The M-doped tin oxides (M = Sb, F, and In) to be used as catalyst support are synthesized by using templating process with tetradecylamine (TDA) as the template, combined with a hydrothermal (HT) method to improve its thermal stability. The obtained materials are characterized by XRD, SAXS, TEM, EDX, SEM, and BET to study microstructure and physical properties, which have a mesoporous structure, small particle size, and high surface area (125-263 m~2 g~(-1)). The materials show an overall conductivity of 0.102-0.295 S cm~(-1). Repetitive potential cycling is employed to characterize the electrochemical properties and stability. The M-doped tin oxides are highly electrochemical stable compared to carbon black. From the observed results, it can be concluded that the combination of TDA and HT treatment are an effective synthetic method for designing mesoporous M-doped tin oxide as catalyst supports.
