Effect of the anatase–rutile contact in gas phase toluene photodegradation quantum efficiency

Novel (NH4)4[NiMo6O24H6]·5H2O – TiO2 composite system: Photo-oxidation of toluene under UV and sunlight-type illumination

“…7) was detected for titania containing samples. In the case of the Ti reference we previously presented this result [36,37]. The deposition of the NiMo 6 component does not affect the stability in the composite sample while a relatively mild decay is observed in the NiMo reference catalyst.…”

“…7. In the majority of the publications reported in the literature, the gas-phase photo-oxidation of toluene renders benzaldehyde as a partial oxidation product and carbon dioxide as the total oxidation one [19,33,36,[38][39][40]. Usually other products such as benzene, formaldehyde and others minor components are toluene-concentration dependent and their concentrations are maximized in conditions of limited water content in the reaction mixture.…”

Facile synthesis of B/g-C3N4 composite materials for the continuous-flow selective photo-production of acetone

“…This sample has a selectivity to acetone approaching 98.5%, which is higher than those for all the previously reported materials, including titania-based materials. 15,[44][45][46][47][48][49][50][51][52] Together with the outstanding activity presented by the composite samples, these results indicated that the B/g-C 3 N 4 composite is a highly active and selective material.…”

Impacts of enhanced microbial-photoreductive and suppressed dark microbial reductive dissolution on the mobility of As and Fe in flooded tailing soils with zinc sulfide

“…The abundant semiconducting minerals in natural sediments and soils, such as hematite, goethite, and rutile, are highly responsive to sunlight [7,9]. Upon illumination, mineral photoelectrons are excited from their valence band to the conduction band of semiconducting minerals, forming photoelectron-hole pairs and triggering a series of redox reactions [10].…”
