“…[13][14][15][16][17][18][19] As an n-type semiconducting material, molybdenum oxide (MoO 3 ) has found important applications in an array of gas sensors, optoelectronics, and catalysis. [20][21][22] However, the wide bandgap (≈3.05 eV) [ 23 ] renders MoO 3 only responsive to UV light, which accounts for less than 5% of the solar energy. In view of sunlight utilization, photocatalysts working under visible light are more promising in that it contributes a major proportion (around 43%) of the entire solar spectrum.…”

“…Molybdenum trioxide (MoO 3 ) is one of the most important layered materials and n-type metal oxide semiconductors, MoO 3 nanomaterials have drawn increasing attention because of their unique properties in many fields such as photochromic and electrochromic devices [1][2][3][4][5][6][7][8][9], energy storage [10][11][12][13][14], gas sensors [15,16] and catalysis [17,18]. Generally, MoO 3 is found to have mainly three crystalline polymorphs, orthorhombic MoO 3 (α-MoO 3 ), monoclinic MoO 3 (β-MoO 3 ) and hexagonal MoO3 (h-MoO 3 ), in which α-MoO 3 is the thermodynamically stable phase with layer structure and has been intensively studied.…”

“…Moreover, no expensive catalytic material like platinum is required. Recently, MoO3-based CH 4 sensors were also reported [134]. However, the sensor was operated at 500 • C and the sensitivity for methane was quite poor.…”
