An overview of a collaborative experimental and theoretical effort toward efficient hydrogen production via photoelectrochemical splitting of water into di-hydrogen and di-oxygen is presented here. We present state-of-the-art experimental studies using hematite and TiO(2) functionalized with gold nanoparticles as photoanode materials, and theoretical studies on electro and photo-catalysis of wa...
The development of the photo-catalysis field is limited by a deficient quantitative assessment photo-activity. interplay between mass and momentum transport together with radiative transfer phenomena taking place at any photo-catalytic reaction or process makes complex such assessment. To reach this goal, review studies measurement, meaning, analysis three types observables. first family observ...
Abstract The direct utilization of light to drive chemical reactions has been considered a promising approach decarbonizing the industry and storing solar energy in form bonds. In this regard, photo‐thermal catalysis emerged as bright strategy due combination thermal non‐thermal contributions sunlight. This enables whole exploitation spectrum providing localized heating thus an enhancement prod...
Photo(electro)catalysis (PEC) is a promising strategy to conduct attractive solar-driven reactions such as CO2 reduction form added-value products, H2 production, and organic substrates oxidation, taking advantage of the spatial separation photocarriers generated in semiconductor-based electrodes. Halide perovskite nanocrystals (PNCs) are attracting increasing attention due their tunable optica...
Abstract Catalytic conversion of CO 2 into chemicals and fuels is a viable method to reduce carbon emissions achieve neutrality. Through thermal catalysis, electrocatalysis, photo(electro)catalysis, can be converted wide range valuable products, including CO, formic acid, methanol, methane, ethanol, acetic propanol, light olefins, aromatics, gasoline, as well fine chemicals. In this mini-review...
CO2 conversion In article number 2100185, Yimin Xuan and co-workers introduced NiCo alloys derived from AlMg hydrotalcite for photothermal synergetic with CH4 ultrahigh light-to-fuel efficiency of 33.8% low carbon deposition rate. The is attributed to the high solar absorptance alloys, unique synergistic catalysis active sites, photo-enhanced reactant activation.
Abstract The tandem catalytic functionalization/carboxylation of double as well triple carbon‐carbon bonds with CO 2 represent an emerging research area in synthetic organic methodology. In particular, the combination mild reaction conditions, stoichiometric acceptor/donorless conditions (visible light photoredox catalysis) and chiral catalysts contributed to a rapid development this intriguing...
