We have developed a new protocol involving the “copper(II) chloride-cesium carbonate” system for the aerobic oxidation of primary alcohols. Cesium carbonates and the solvents such as toluene and 1,2-dichloroethane play important roles to form a catalytically active intermediate containing a m-hydroxyl-bridged trinuclear copper moiety (complex 1). From the X-ray crystal structure of complex 1, a...

Strain T1 is a facultative bacterium that is capable of anaerobic toluene degradation under denitrifying conditions. While 80% of the carbon from toluene is either oxidized to carbon dioxide or assimilated into cellular carbon, a significant portion of the remainder is transformed into two dead-end metabolites. These metabolites were produced simultaneous to the mineralization of toluene and we...

In this work, the synthesis of nickel particles encapsulated in a few-layer graphene shell was carried out using method electric arc discharge liquid phase, various media: deionized water, alcohol, and toluene. Nickel graphite were used as electrodes. The study to analyze how liquids, acting cooling medium source carbon, affect formation protective around metal particles. Raman studies, analysi...

Correction for ‘Understanding the suppressive role of catalytically active Pt–TiO 2 interfacial sites supported metal catalysts towards complete oxidation toluene’ by Hanlei Sun et al. , J. Mater. Chem. A 2022, 10 25633–25643, https://doi.org/10.1039/D2TA07555E.

The oxidation of toluene in air was investigated using a dielectric barrier discharge (DBD) combined with a Pd/Al2O3 catalyst. When using only plasma, rather low selectivity toward CO2 was obtained: 32-35%. By filling the DBD reactor with Pd/Al2O3 catalyst the CO2 selectivity was significantly enhanced (80-90%), however, a large amount of toluene was desorbed from the catalyst when the discharg...

We have produced passivating coatings on 80-nm aluminum particles by plasma-enhanced chemical vapor deposition (PECVD). Three organic precursors--isopropyl alcohol, toluene, and perfluorodecalin--were used to fabricate thin films with thicknesses ranging from 5 nm to 30 nm. The coated samples and one untreated sample were exposed to 85% humidity at 25 °C for two months, and the active Al conten...

We are using directed evolution to extend the range of dioxygenase-catalyzed biotransformations to include substrates that are either poorly accepted or not accepted at all by the naturally occurring enzymes. Here we report on the oxidation of a heterocyclic substrate, 4-picoline, by toluene dioxygenase (TDO) and improvement of the enzyme's activity by laboratory evolution. The biotransformatio...
