With careful rational optimization and substantial simplification of the syntheses recently reported alloys BiO(ClxBr1–x), we fabricated, via a very simple procedure at room temperature, unique visible-light-driven photocatalyst with excellent activity. The alloy BiOCl0.875Br0.125 totally decomposed 15 mg/L aqueous Rhodamine B solution within 120 s upon irradiation visible light (λ > 422 nm). transparent substrate acetophenone was also swiftly destroyed under above conditions. catalyst...

In this study, a facile and effective method to modify the photocatalytic performance of bismuth oxybromide (BiOBr) semiconductor through fabrication heterojunction with hydrated oxide (BHO) is reported. The new yBiOBr-(1 – y)BHO heterojunction, synthesized by simple hydrothermal method, exhibits high activity under visible light irradiation for photodegradation typical organic pollutants in water, such as Rhodamine B (RhB) acetophenone (AP). Both individual BiOBr BHO components show very...

Allylic and benzylic alcohols were oxidized in good yields to the respective ketones by tert-butyl hydroperoxide (TBHP) presence of copper salts under phase-transfer catalysis conditions. This dehydrogenation was found proceed via a heterolytic mechanism. CuCl2, CuCl, even powder equally facile as catalysts, they all transformed situ Cu(OH)Cl which extracted into organic phase catalyst (PTC). Deuterium labeling experiments evidenced scission C–H bond rate-determining step. Nonproductive TBHP...

Potassium triphosphate is a surprisingly active catalyst for the catalytic transfer hydrogenation of carbonyl compounds. A pretreatment at 600 °C critical to obtain material. Temperature programmed desorption CO2 indicates that sites lower basicity were created after heat treatment 5 h as compared 1 h. With 2-propanol hydride source, aromatic aldehydes reduced corresponding alcohols with high rates. The presence electron withdrawing chloro- and nitro-substituents benzene ring increases rate...

Following our report on the fabrication of BiOClxBr1–x (0 ≤ x 1) alloys, and via careful rational optimization substantial tuning, we upgraded previous photocatalytic system by means a controlled doping with elemental bismuth particles. The latter leads to formation well-defined structures characterized effective separation electron–hole pairs more reductive photoexcited electrons. These advanced semiconductors, specifically heterojunctioned doped were synthesized simple soft chemical route...
