A bifunctional tungstate catalyst for chemical fixation of CO2 at atmospheric pressure

No pressure: A simple monomeric tungstate, [WO4]2-, serves as a highly efficient homogeneous catalyst for various transformations of CO2 at atmospheric pressure. The tungsten-oxo moiety activates CO2 and the substrate simultaneously. The catalyst system is high yielding and applicable to a wide range of substrates such as amines (see scheme), 2-aminobenzonitriles, and propargylic alcohols. Copyright

CdSnO3/SnD NPs as a Nanocatalyst for Carbonylation of o-Phenylenediamine with CO2

In order to carbonize o-phenylenediamine with CO2, an effective approach was used with UV light irradiation by Sn(IV) doping DFNS (SnD) supported CdSnO3 as a catalyst (CdSnO3/SnD). In this catalyst, SnD with the ratios of Si/Sn in the range of 6 to 50 were obtained using the Direct Hydrothermal Synthesis (DHS), and the nanoparticles of CdSnO3 on the surfaces of SnD were reduced in situ. Scanning Electron Microscope (SEM), X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), X-ray Energy Dispersive Spectroscopy (EDS), and Transmission Electron Microscopy (TEM) were utilized for characterizing CdSnO3/SnD. It was found that CdSnO3/SnD nanostructures could be used for synthesizing o-phenylenediamines due to their effective and novel catalytic behavior through the reaction between o-phenylenediamines and CO2.

PrVO4/SnD NPs as a Nanocatalyst for Carbon Dioxide Fixation to Synthesis Benzimidazoles and 2-Oxazolidinones

Recently CO2 stabilization has received a great deal of attention because of its probable applications as a rich C1 resource and the synthesis of several fine chemicals can be accomplished through this stabilization. In this study, Sn(IV) doping dendritic fibrous nanosilica (SnD) supported PrVO4 nanoparticles as a catalyst (PrVO4/SnD) was synthesized by a in-situ procedure. The SnD with the ratios of Si/Sn in a variety of 6 to 40 were acquired through direct hydrothermal synthesis (DHS), and PrVO4 NPs on the surfaces of SnD were reduced in-situ. X-Ray diffraction (XRD), Scanning electron microscope (SEM), Fourier transform infrared spectroscopy (FT-IR), transmission electron microscopy (TEM), and X-ray energy dispersive spectroscopy (EDS) were deployed for identifying the PrVO4/SnD. It is potentially a highly dynamic catalyst in the stabilization of CO2 for the production of 2-oxazolidinones and benzimidazoles. In addition, the catalyst is very easy to recycle and reuse without significant loss of active site Cu metal.

Application of sea urchin-shaped cobalt-based photocatalyst in synthesis of benzoazacycle by converting CO2

The invention relates to the technical field of photocatalysis, in particular to application of a sea urchin-shaped cobalt-based photocatalyst to synthesis of benzoazacycle by converting CO2. A complex is of a sea urchin-shaped microsphere structure, which is composed of an organic ligand L and cobalt nitrate hexahydrate and is formed by arranging a plurality of nano needle-shaped complex crystals. The main body of the organic ligand L is p-aminobenzoic acid; the application comprises the following steps: introducing CO2 into a solution containing o-phenylenediamine compounds, carrying out carbonylation reaction and cyclization with o-phenylenediamine compounds under the action of the urchin-shaped cobalt-based catalyst to generate the benzoazacycle compounds. The sea urchin-shaped microsphere structure cobalt-based catalyst formed by the obtained nano needle-shaped complex crystal has a very large specific surface area and high photocatalytic efficiency; when the photocatalyst is adopted to catalyze and activate CO2, the reaction for synthesizing the benzoazacycle by converting CO2 can be carried out at room temperature, so that the energy consumption is greatly reduced, and the cost is reduced.
