“…Platinum (Pt) is one of the most effective catalysts for sensing reducing gases, including hydrogen, carbon monoxide, and hydrocarbon, by chemical sensitization or spillover effect [128]. Together with it, several MO x materials like, WO 3 [129], ZnO [130], TiO 2 [131], MoO 3 [132], and Nb 2 O 5 [133] have been used. The newly designed and produced prototype sensor using ZnO-SnO 2 composite material was investigated for its gas sensing behaviour at dissimilar concentrations of hydrogen gas at various temperatures.…”

Considering metal oxide nanoparticles as important technological materials, authors provide a comprehensive review of researches on metal oxide nanoparticles, their synthetic strategies, and techniques, nanoscale physicochemical properties, defining specific industrial applications in the various fields of applied nanotechnology. This work expansively reviews the recent developments of semiconducting metal oxide gas sensors for environmental gases including CO 2 , O 2 , O 3 , and NH 3 ; highly toxic gases including CO, H 2 S, and NO 2 ; combustible gases such as CH 4 , H 2 , and liquefied petroleum gas; and volatile organic compounds gases. The gas sensing properties of different metal oxides nanoparticles towards specific target gases have been individually discussed. Promising metal oxide nanoparticles for sensitive and selective detection of each gas have been identified. This review also categorizes metal oxides sensors by analyte gas and also summarizes the major techniques and synthesis strategies used in nanotechnology. Additionally, strategies, sensing mechanisms and related applications of semiconducting metal oxide materials are also discussed in detail. Related applications are innumerable trace to ultratrace-level gas sensors, batteries, magnetic storage media, various types of solar cells, metal oxide nanoparticles applications in catalysis, energy conversion, and antennas (including microstrip and patch-type optically transparent antennas), rectifiers, optoelectronic, and electronics.

“…Titanium dioxide has been used as a building block to develop new nanoarchitectures with advanced properties for achieving high-performance sensing [1][2][3][4], improved photocatalytic power [5,6], and superior photovoltaic results [7,8]. Similarly, carbon nanotubes (CNTs) are graphene sheets rolled up to build seamless tubes with nanometric diameters with outstanding electronic, chemical and physical properties, in such a way that the design of carbon hybrid materials with potential applications as efficient molecular sensors has become an active area of research [9][10][11][12][13][14][15][16][17].…”
