我们提出了一种直接软模板法来合成介孔二氧化锡网络，其在400 °C和500 °C煅烧后保持多孔结构，并且具有分别为220和100 m2 g-1的相对高的BET表面积。TEM、BET和XRD结果证实，由于在煅烧步骤期间增加温度，晶体尺寸和孔径都增加。该方法重现性好。
We present a direct soft templating method to synthesise mesoporous tin dioxide network that maintains a porous structure after calcination at 400 °C and 500 °C and has a relatively high BET surface area of 220 and 100 m2 g-1, respectively. TEM, BET and XRD results confirm that both crystal and pore sizes increase as a result of increasing the temperatures during the calcination step. This method is highly reproducible.
