The use of tin oxide in fuel cells

Additives in Nanocrystalline Tin Dioxide: Recent Progress in the Characterization of Materials for Gas Sensor Applications

“…Tin dioxide SnO 2 is an important representative of the group of n-type wide-bandgap (E g = 3.6 eV) semiconductor oxides (SnO 2 , ZnO, In 2 O 3 , TiO 2 , and WO 3 [1]) with a unique combination of high transparency, electrical conductivity, high surface reactivity, and stability in air. Tin dioxide has huge potential and is widely studied and used for applications in different fields [2,3], in particular for the manufacturing of optically passive components in a number of devices [4][5][6], including photodetectors [7][8][9][10][11][12], solar cells [13][14][15][16], conductive ceramics [17][18][19][20][21][22], varistors [23], transparent electrodes [24][25][26][27][28], electrochromic coatings [29][30][31][32][33][34], transistors [35][36][37], components of fuel cells [38] and metal-ion batteries [39], catalysts [40], and chemical sensors [2,[41][42][43]…”

A review on tin dioxide gas sensor: The role of the metal oxide doping, nanoparticles, and operating temperatures

“…Tin (IV) Oxide (SnO2) is an n-type transparent semiconductor with a wide bandgap of 3.6 eV at 300 K [12,13]. SnO2 is used in a wide variety of applications, including photovoltaic devices [14][15][16][17][18], biological applications [19][20][21][22][23], solar cells [24][25][26][27][28], electrochemical applications [29][30][31], and gas sensors [32][33][34][35][36][37]. Due to its high sensitivity to reducing and oxidizing gases such as CO, H2, and NO, tin oxide is commonly employed in gas sensor applications.…”
