Photochemical reduction of carbon dioxide coupled with water oxidation using various soft-oxometalate (SOM) based catalytic systems

“…46 The catalytic activity of SOMs has also been explored in various types of reactions viz., in photo-polymerization [54][55][56] and photochemical water oxidation. 57 In this article we have shown that SOM type materials based on oxo-molybdate and oxo-tungstate clusters can efficiently catalyse the reduction of CO 2 to HCOOH/HCHO by transferring the electrons and protons generated from oxidation of water. The catalysts reported here present a new opportunity as they provide a method that is scalable and fast with a very high turnover number.…”

Light driven decarboxylative cross coupling of acrylic acid and iodobenzene using [Mo 132 ] type keplerate as a catalyst

“…Also polyoxometalates are photoactive and generally stable under photochemical conditions. POMs have been used as photocatalyst in different photopolymerization reaction and organic reactions by us already [38][39][40][41][42]. Thus we are now interested to use those giant POMs in photo catalytic organic coupling reaction.…”

Light Driven Water Oxidation Coupled With C‐N Coupling Reaction Using a Hybrid Cu‐PW12O40 Based Soft‐Oxometalate

“…POMs are generally ionic in nature with high charge and a number of hydrogen bonding sites, which provides the possibility to synthesize composites with different electro active surfaces such as graphene, graphene oxide, different LDHs ,. The immobilization of the POM moiety on the electro active surface can enhance the catalytic activity of these materials ,. POMs can also exist in a colloidal state of soft‐oxometalates (SOMs) .…”

“…POMs can also exist in a colloidal state of soft‐oxometalates (SOMs) . We have recently shown that soft oxometalates based on several different oxometalates can act as active catalyst for photo chemical oxidation of water without the need of a photosensitizer and a sacrificial electron donor , Further CO 2 can be transformed into other energy dense organic compounds like formic acid and formaldehyde by H 2 O in presence of light using SOMs .…”
