Specific surface area and pore volume of m-SnO_2 prepared from C_16PyCl ((C_5H_5NC_<16>H_<33>)Cl?H_2O) and Na_2SnO_3?3H_2O (m-SnO_2(1)) were larger than those of m-SnO_2 prepared from AOT (C_<20>H_<37>O_7SNa) and SnCl_4?5H_2O (m-SnO_2(2)). However, the specific surface area of m-SnO_2(1) decreased dramatically by grinding, while m-SnO_2(2) with small secondary agglomerates showed a little decrease in the specific surface area and better H_2 response with low resistance in air than m-SnO_2(1), especially at low operating temperature., text, Nagasaki Symposium on Nano-Dynamics 2008 (NSND2008) 平成20年1月29日(火)於長崎大学 Poster Presentation, Nagasaki Symposium on Nano-Dynamics 2008 (NSND2008), pp.81-82}, pages = {81--82}, title = {Microstructural effects of mesoporous SnO_2 powders on their H_2 sensing properties}, year = {2008} }
