Ultraselective and ultrasensitive detection of trimethylamine using MoO3 nanoplates prepared by ultrasonic spray pyrolysis

Ultrasensitive detection of trimethylamine using Rh-doped SnO2 hollow spheres prepared by ultrasonic spray pyrolysis

“…The present authors have reported that both WO 3 hollow spheres and MoO 3 nanoplates prepared by ultrasonic spray pyrolysis and subsequent heat treatment show high responses to TMA with low cross-responses to other reducing gases, including C 2 H 5 OH [16,17]. The high responses to TMA were attributed to the strong interaction between basic TMA gas and acidic WO 3 and MoO 3 , as well as to effective electron depletion owing to thin shells or plates.…”

“…It has been reported that many oxide semiconductors exhibit a response to TMA [6][7][8][9][10][11][12][13]. In pure oxide semiconductor gas sensors, the response to TMA has been enhanced by increasing the gas accessibility [14][15][16], decreasing the size of the nanostructures [17], and/or using the interaction between basic TMA gas and acidic sensing materials [16,17].

Facile and low cost oxidative conversion of MoS2 in α-MoO3: Synthesis, characterization and application

“…All spectra were adjusted according to the value of the C 1s peak at 284. 4 . analyses (XPS/UPS) were done with equipment from SPECS using an energy analyzer PHOIBOS 150.…”

“…Being a versatile material and widely used in industry, the molybdenum trioxide (MoO3) has been subject of many studies over the past decade. An important layered oxide, MoO3 presents attractive multifunctional properties, and have attracted considerable interest in many different applications, such as oxidative alcohols catalysis [1] and degradative dyes photocatalysis [2], also in batteries with other ions [3,4], sensors gas [5] and solar cells [6].…”

Enhanced catalytic reduction of para-nitrophenol using α-MoO3 molybdenum oxide nanorods and stacked nanoplates as catalysts prepared from different precursors

“…Many studies describe methods to obtain MoO 3 with different nanostructures. The nanostructures include nanobelts, nanorods, nanoplates, nanotubes, nanoflakes, nanoribbons, nanofibers, nanosheets, nanoplatelets or nanowires that were synthesized as powders or deposited as films using different experimental methods, such as hydrothermal, solvothermal, solvo-combustion, spray pyrolysis, thermal evaporation or electrochemical processes [19][20][21][22][23][24][25][26][27][28][29][30].…”
