Immobilization of g-C₃N₄ nanosheets on diatomite via electrostatic adsorption and their photocatalytic activity

Abstract

g-C3N4/diatomite hybrids were synthesized through an electrostatic adsorption method and subsequent calcination process.

Efficient degradation of VOCs using semi-coke activated carbon loaded ternary Z-scheme heterojunction photocatalyst BiVO4–BiPO4–g-C3N4 under visible light irradiation

“…The band at 812 cm −1 can be ascribed to the plane skeletal bending modes of the triazine cycles. 62,63 Besides, the broad absorptions at 3447 cm −1 , 2989 cm −1 , and 1600 cm −1 were related to the O–H stretching H–O–H band, which is due to water molecule's adsorption on the surface area. The peaks of pure BiVO 4 , BiPO 4 and g-C 3 N 4 appear in the spectrum of the PVCN/SAC, which corresponds to the XRD results.…”

“…The bands at 1317 and 1238 cm À1 were related to the stretching vibration of the connected units of C-N(-C)-C or C-NH-C, respectively. The band at 812 cm À1 can be ascribed to the plane skeletal bending modes of the triazine cycles 62,63. Besides, the broad absorptions at 3447 cm À1 , 2989 cm À1 , and 1600 cm À1 were related to the O-H stretching H-O-H band, which is due to water molecule's adsorption on the surface area.…”

Combined Heterogeneous Catalyst Based on Titanium Oxide for Highly Efficient Oxidative Desulfurization of Model Fuels

“…Titanium oxide is of particular interest among carriers due to its unique physicochemical properties, non-toxic nature, relative cheapness, and accessibility, as well as due to its resistance to ultraviolet irradiation and stability for aggressive oxidant treatment. , The application of titanium oxide with various additives as a catalyst for oxidative desulfurization under ultraviolet irradiating is known. − Despite the high activity at low temperatures, such catalysts have significant drawbacks when introduced to industrythe use of light for hydrogen peroxide decomposition. Approaches for the production of titanium-containing catalysts that do not require UV radiation are known in the literature. − These catalytic systems require a sufficiently long time of oxidation, and therefore the task is to develop catalysts in the presence of which oxidation will take place without UV and in a minimum contact time.…”
