“…Many researches have shown that the semiconductor SnO 2 material is of potential applicability in gas sensors, glass electrodes, secondary lithium batteries, solar cells, transistors and catalysts [4][5][6]. In recent years, doped SnO 2 and SnO 2 -based materials, such as Sb-doped SnO 2 , Mn-doped SnO 2 , Zn 2 SnO 4 , Cd 2 SnO 4 and so on, have been studied extensively due to their special optical and electrical properties [7][8][9][10]. On the other hand, the chemical and physical properties of these materials also depend on the sizes and shapes of particles.…”
