A direct Z-scheme α-Fe2O3/LaTiO2N visible-light photocatalyst for enhanced CO2 reduction activity

Construction of a 2D/2D WO3/LaTiO2N Direct Z-Scheme Photocatalyst for Enhanced CO2 Reduction Performance Under Visible Light

“…The crystal structures of the as-prepared samples have been ascertained by XRD. As shown in Figure a, pure LTON displays the diffraction peaks at 22.5, 32.1, 39.5, 45.9, and 57.2°, which are attributed to the characteristic diffraction peaks of orthogonal LaTiO 2 N . The diffraction peaks of bare WO 3 at 23.1, 23.6, 24.3, 33.2, and 34.1° correspond to the characteristic diffraction peaks of monoclinic WO 3 .…”

“…Converting solar energy into hydrocarbons via artificial photosynthesis is an appealing way potentially to resolve the energy crisis and environmental problems of the modern society . Fixation of CO 2 by photocatalysis not only produces carbon chemicals or fuels but also closes the carbon cycle to minimize the greenhouse effect. − In the past decades, a number of semiconductors have been exploited and applied for photocatalytic CO 2 reduction, such as g-C 3 N 4 , , metal oxide, , LaOCl, LaTiO 2 N, and others. However, recent investigations have shown high recombination probability of photoinduced carriers and low sunlight utilization by a species of semiconducting photocatalysts. − Accordingly, it is imminent to exploit composite photocatalysts to achieve better separation of charge carriers and utilization of solar energy. , …”

Core–shell Cu@Cu2O nanoparticles embedded in 3D honeycomb-like N-doped graphitic carbon for photocatalytic CO2 reduction

“…1,2 The burning of fossil fuels and extensive deforestation have significantly increased the level of carbon dioxide in the atmosphere. 3,4 Therefore, in addition to controlling CO 2 production, scientists are developing ambitious strategies, such as CO 2 capture [5][6][7] and storage (CCS) 8,9 and CO 2 utilization. 10 One of the attractive approaches is the photocatalytic reduction of CO 2 , which can reduce the greenhouse effect and convert CO 2 and solar energy into value-added chemical feedstocks (C 1 : CO, CH 4 , and HCOOH; C 2 : ethylene, ethanol, etc.).…”

2D–3D graphene-coated diatomite as a support toward growing ZnO for advanced photocatalytic degradation of methylene blue

“…Among various environmental pollution treatment technologies, photocatalysis with semiconductor oxides as catalysts can deeply mineralize and decompose harmful substances and has become an ideal technology for dye wastewater pollution treatment. 12,13 Aer years of investigation, semiconductor materials such as LaTiO 2 N, 14 ZnO, Fe 2 O 3 , 15 selenium-enriched amorphous NiSe1 + x nanoclusters, 16 and CdS 17 have been found to have photocatalytic functions and have received considerable attention. Among them, the ZnO photogenerated electron-hole pair binding energy can reach 60 meV, 18 and it exhibits high photocatalytic activity, and has good photochemical stability, low cost and low toxicity, meaning that it is frequently used for the degradation of organic pollutants.…”
