TiO2/g-C3N4 photocatalysts with the ratio of TiO2 to g-C3N4 ranging from 0.3/1 2/1 were prepared by simple mechanical mixing pure and commercial Evonik P25. All nanocomposites characterized X-ray powder diffraction, UV–vis diffuse reflectance spectroscopy, photoluminescence, photoelectron Raman infrared transmission electron microscopy, photoelectrochemical measurements, nitrogen physisorption. The mixtures along tested for photocatalytic reduction carbon dioxide decomposition nitrous oxide....
Graphitic carbon nitride (g-C3N4) was obtained by thermal polymerization of dicyandiamide, thiourea or melamine at high temperatures (550 and 600 °C), using different heating rates (2 10 °C min-1) synthesis times (0 4 h). The effects the conditions type precursor on efficiency g-C3N4 were studied. most efficient from 53%, while in process much smaller, 26% 11%, respectively. On basis results provided X-ray diffraction (XRD), photoelectron spectroscopy (XPS), infrared (FTIR),...
The efficient gas phase photocatalytic hydrogenation of CO<sub>2</sub> opens a feasible route not only to store H<sub>2</sub> by converting it into renewable fuel, but also reduce the amount greenhouse in atmosphere.
Photocatalysis is increasingly becoming a center of interest due to its wide use in environmental remediation. Hematite (α-Fe2O3) one promising candidate for photocatalytic applications. Clay materials as vermiculite (Ver) can be used carrier accommodate and stabilize photocatalysts. Two different temperatures (500 °C 700 °C) were preparation α-Fe2O3 nanoparticles/vermiculite clay materials. The experimental methods determination structural, optical properties X-ray fluorescence (ED-XRF),...
In this study, we explored the photocatalytic efficacy of Ti3+-doped TiO2-based photocatalysts for CO2 reduction. The Ti3+ self-doped were synthesized using a straightforward chemical reduction with sodium borohydride (NaBH4). Our investigation aimed to elucidate intricate interplay between synthesis process and quantity NaBH4 reductant on physical-chemical attributes defective photocatalysts. We three different commercially available TiO2 materials labeled P25, (S)TiO2, KRONOClean7050,...
