BiVO4 quantum tubes loaded on reduced graphene oxide aerogel as efficient photocatalyst for gaseous formaldehyde degradation

Insights into light and mass transport in nanoparticle-based aerogels: the advantages of monolithic 3D photocatalysts

“…[21][22][23] Unfortunately, so far, the activity of monolithic aerogels have been reported only in terms of reaction rates due to the design limitations of the reactors used. 15,[24][25][26] For gas-phase reactions, typically tubular reactors are used, in which a cylindrical aerogel is placed inside of a quartz glass tube and illuminated laterally. The cylinder curvature makes it difficult to measure accurately the incident light that is essential to calculate AQE.…”

Improvement in NO2 Gas Sensing Properties of Semiconductor-Type Sensors by Loading Pt into BiVO4 Nanocomposites at Room Temperature

“…One common approach to NO 2 detection involves nanostructures of bismuth vanadate (BiVO 4 ). Beyond NO 2 detection [8][9][10], BiVO 4 has been used in a wide variety of applications, such as formaldehyde degradation [11,12], H 2 S production [13,14], hydrogen production [15,16], CO 2 capture [17,18], and other fields [19][20][21]. Table 1 lists a variety of NO 2 sensors based on Pt or BiVO 4 .…”

Simultaneous enhanced electrochemical and photoelectrochemical properties of α-Fe2O3/graphene by hydrogen annealing

“…Transition metal oxides are attractive electrode materials due to their excellent pseudocapacitive properties and photoelectrical properties, including TiO 2 , ZnO, Fe 2 O 3 , V 2 O 5 , Co 3 O 4 , SnO 2 , BiVO 4 , and WO 3 , etc [6][7][8][9][10][11][12]. Hematite (α-Fe 2 O 3 ) is one of the most typical n-type semiconductor materials.…”
