A roadmap towards the development of superior photocatalysts for solar- driven CO2-to-fuels production

Tailor‐Engineered 2D Cocatalysts: Harnessing Electron–Hole Redox Center of 2D g‐C3N4 Photocatalysts toward Solar‐to‐Chemical Conversion and Environmental Purification

“…[59] The product selectivity relies solely on the obtained electrons and hydrogen radicals, which are controlled by the development of nanostructures and the existence of photoactive materials in g-C 3 N 4 based semiconductors. [87] This phenomenon has been elucidated by the group of Varma et al [124] and Peng et al [125] Intriguingly, the current investigation revealed that the reactivity of 2D g-C 3 N 4 based photocatalysts is limited to only loworder hydrocarbon fuels such as CO and CH 4 . [126] g-C 3 N 4 with a thin-layered structure has a larger bandgap than its bulk form, leading to a greater difference in electronic band level between redox reaction and the band edges.…”

Editorial: From CO2 Emissions to Fuels and Chemicals: Current Development, Challenges and Perspectives

“…For example, converting CO 2 into polyols could enable the production of more sustainable elastomers, fibers, flexible foam, adhesives, sealants, inks, paints, and coatings. Another route that can be considered is the conversion of CO 2 in valuable energy carriers such as methane, methanol, etc., which could be an attractive CCU solution while simultaneously addressing global warming and storing of hydrogen energy or renewable energy in commonly used dense energy carriers [4][5][6]. However, for all the routes and targeted products, it is important to ensure that CCU pathways deliver the three following aspects: 1) sustainable cradle-tograve solutions 2) economically viable solutions 3) scalable solutions.…”

Immobilized Molecular Catalysts for CO2Photoreduction

“…Numerous studies are based on TiO 2 derivatives, but ZrO 2 is also used frequently together with other metal sulfides or oxonitrides. [40][41][42] Carbon-based nanocomposites have also shown great potential as catalysts for CO 2 photoreduction. [43,44] Under photoexcitation, these materials promote electrons to the conduction band, which are available to reduce CO 2 .…”
