چکیده

Abstract Photocatalytic water splitting and carbon dioxide photoreduction are considered effective strategies for alleviating the energy crisis environmental pollution. Polynuclear metal-oxo clusters possess excellent electron storage/release ability unique catalytic properties via intermetallic synergy, which enables them with great potential in environmentally friendly photosynthesis. Importantly, precise structure can not only act as high-efficiency catalysts but also provide well-defined structural models exploring structure–activity relationships. In this review, we systematically summarize recent progress application of polynuclear clusters, including polyoxometalate low-cost transition metal metal-oxo-cluster-based metal–organic frameworks CO 2 reduction. Furthermore, discuss challenges solutions to problems - oxo photocatalysis.

Photocatalytic carbon dioxide reduction with rhodium-based catalysts in solution and heterogenized within metal-organic frameworks.

The first photosensitization of a rhodium-based catalytic system for CO2 reduction is reported, with formate as the sole carbon-containing product. Formate has wide industrial applications and is seen as valuable within fuel cell technologies as well as an interesting H2 -storage compound. Heterogenization of molecular rhodium catalysts is accomplished via the synthesis, post-synthetic linker e...

Metal–Organic Frameworks and Their Derivatives for Photocatalytic Water Splitting

Amongst many strategies for renewable energy conversion, light-driven water splitting to produce clean H2 represents a promising approach and has attracted increasing attention in recent years. Owing to the multi-electron/multi-proton transfer nature of water splitting, low-cost and competent catalysts are needed. Along the rapid development of metal–organic frameworks (MOFs) during the last tw...

Photocatalytic reduction of carbon dioxide by water on titania: Role of photophysical and structural properties

Photocatalytic reduction of carbon dioxide has been investigated on three different titania catalysts (two commercial titania, De Gussa P-25 and UV-100 Hombikat and another catalyst prepared by sol-gel method under reverse micelle environment) dispersed in aqueous alkaline medium under irradiation in visible region (300-700 nm) from Hg lamp. The catalysts have been characterized by XRD, diffuse...

High-valent metal-oxo intermediates in energy demanding processes: from dioxygen reduction to water splitting.

Four-electron reduction of dioxygen to water and splitting of water to dioxygen are extremely important processes in the context of attaining clean renewable energy sources. High-valent metal-oxo cores are proposed as reactive intermediates in these vital processes, although they have only been isolated in extremely rare cases in the biological systems thereby making the mechanism ambiguous. Re...

Nanocomposites of tantalum-based pyrochlore and indium hydroxide showing high and stable photocatalytic activities for overall water splitting and carbon dioxide reduction.

Nanocomposites of tantalum-based pyrochlore nanoparticles and indium hydroxide were prepared by a hydrothermal process for UV-driven photocatalytic reactions including overall water splitting, hydrogen production from photoreforming of methanol, and CO2 reduction with water to produce CO. The best catalyst was more than 20 times more active than sodium tantalate in overall water splitting and 3...
