Evaluation of the role played by bismuth molybdates in Bi2Sn2O7–MoO3 catalysts used for partial oxidation of isobutene to methacrolein

Facile Synthesis of BiOBr/Bi2Sn2O7 Heterojunction Photocatalysts with Improved Photocatalytic Activities

“…Recently, bismuth‐based semiconductors, including BiOX (X = Cl, Br, and I), BiVO 4, Bi 2 WO 6 , and Bi 2 Sn 2 O 7, have attracted much attention due to their outstanding photo‐oxidation activity. Bi‐based semiconductors are believed to possess the hybridized energy band structures, which can effectively suppress the recombination of photogenerated electrons and holes .…”

Synthesis and Characterization of Pyrochlore Bi2Sn2O7Doping with Praseodymium by Hydrothermal Method and Its Photocatalytic Activity Study

“…As a kind of pyrochlore-type composite oxides, bismuth pyrostannate (Bi 2 Sn 2 O 7 ) has received considerable attention by a number of groups due mainly to its demonstrated applications in catalysis and gas sensing [15][16][17][18]. Moens et al [19] used Bi 2 Sn 2 O 7 (BSO) mechanically mixed with MoO 3 to evidence a cooperation catalytic effect between BSO and Bi 2 Mo 3 O 12 . Kim et al [20] utilized a novel method to prepare SnO 2 nanowires with BSO nanoparticles and investigated its oxygen sensing properties.…”

Nanomaterials for Sensing Applications

“…According to literature survey many researchers have shown that the various kind of nanomaterials including different dopant, catalysis, adhesive, binders, surfactant all have been used to enhance the sensing characteristics of sensors made from these materials. In addition to the above, their film fabrication method also provides another variable for sensor design [33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52]. As a simple review of nanomaterials for sensing applications, this article will focus on the principle, film deposition method and use of a range of nanomaterials for gas sensors.…”
