The super microporous tin‐doped zirconium oxides were successfully synthesized by sol‐gel method using zirconyl chloride as Zr source, tin chloride as Sn source and cetyltrimethylammonium bromide (CTMAB) as template under hydrothermal or refluxing conditions. The structures of the resultant materials were characterized by XRD, BET, FTIR, TG‐DTA, XRF and HRTEM techniques. Experimental results indicated that the framework of the samples is typically ordered hexagonal structure. The surface area and pore volume of the materials prepared by refluxing method were larger than by hydrothermal method, but the ordering of pore distributions is lower. The thermal stability of the samples was relatively high (>773 K) and decreased with the increment of tin content.
