Temperature-dependent hydrogen sensing characteristics of a new Pt/InAlAs Schottky diode-type sensor

CO2gas detection properties of a TIO2/Al2O3heterostructure under UV light irradiation

“…Taking photocatalysis as an example, fast recombination of photo-generated electron-hole pairs in the single semiconductor can be effectively suppressed, thus improving the efficiency of net charge transfer in the reaction process by fabricating heterostructures. Regarding gas sensing applications, the heterostructures cause higher responses due to the formation of a more extended depletion layer [17][18][19].…”

Hydrogen Leakage Sensing and Control: (Review)

“…Figure 2 shows the schematic diagram of MOX sensor [3]. The performance of a MOX sensor can be permanently corrupted when exposed to certain silicon compounds (which may include common industrial sealants and lubricants) [32][33][34][35][36][37][38][39][40]. These sensors typically need oxygen for stable responses and should not been widely applied to process streams or very high concentrations of H 2 [41], thus these devices cannot be readily installed in a nitrogen-purged environment.…”
