“…The group of Papadogianakis has used a similar water-soluble catalyst, Rh/TPPTS [TPPTS = P(C 6 H 4 -m-SO 3 Na) 3 ], for the hydrogenation of benzene to cyclohexane with high catalytic activities, turnover frequency (TOF = 204 000 h À1 ), and good recyclability. [9] Interestingly, the same catalyst system has shown excellent results for the selective hydrogenation of crude polyunsaturated methyl esters of linseed, sunflower, and soybean oils to achieve high selectivities, up to 79.8 mol %, of monounsaturated (C18:1) fatty acid methyl esters. [10] A different strategy to immobilize the catalyst in the water phase is the covalent attachment of the catalyst to supports such as silica, polymers, dendrimers, cyclodextrins, and others.…”

Solving problems: Reduction reactions are important chemical transformations, widely used on both the laboratory and industrial scale. Thus, the importance of these chemical transformations necessitates research towards alternative, greener solvent systems, to reduce any negative impact on the environment. This Minireview is focused on three alternatives for conducting reduction reactions: water, supercritical carbon dioxide, and ionic liquids.

“…The XRD patterns of WO 3 and Rh NPs/WO 3 show that there is no change in the position of the characteristic diffraction peaks of tungsten(VI) oxide after Rh loading (Figure 1). This observation indicates that WO 3 remains intact after the impregnation and reduction of Rh 3+ ions on the surface of tungsten(VI) oxide powder.…”

Ö ZR odyum(III) iyonları ilk önce sulu çözelti içinde tungsten(VI) oksit (WO 3 ) üzerine tutturulmuş ve WO 3 yüzeyi üzerinde rodyum(0) nanoparçacıkları (Rh NPs) oluşturmak için sulu NaBH 4 ile indirgenmiştir. Rh NPs/WO 3 katalizörü santrifüjleme ile ayrıldıktan sonra gelişmiş analitik tekniklerle tanımlanmıştır. Sonuçlar Rh NPs'nin başarılı bir şekilde WO 3 yüzeyinde oluştuğunu göstermektedir. Rh NPs/WO 3 katalizörünün 131 h-1 çevrim frekansı değeri ile 25.0±0.1ºC' de solventsiz benzen hidrojenlenmesinde çok aktif olduğu bulunmuştur Anahtar Kelimeler Tungsten(VI) oksit, rodyum nanoparçacıkları, benzen, hidrojenlenme. A B S T R A C TR hodium(III) ions were first impregnated on the surface of tungsten(VI) oxide (WO 3 ) in aqueous solution and reduced with aqueous NaBH 4 to form rhodium(0) nanoparticles (Rh NPs) on the surface of WO 3 . After the isolation of the Rh NPs/WO 3 catalyst by centrifugation, it was characterized by advanced analytical techniques. The results reveal the successful formation of Rh NPs on the surface of WO 3 . Rh NPs/WO 3 catalyst with a turnover frequency value of 131 h-1 was found to be very active in hydrogenation of neat benzene at 25.0±0.1ºC.
