Metal-ceramic composites for photocatalytic oxidation of diclofenac in aqueous solution

Photocatalytic activity of metal‐ceramic composites synthesized by self‐propagating high‐temperature synthesis (SHS) is investigated in the processes of degradation of diclofenac (DCF). Optical properties of the composites were studied, and the band gaps of ceramic matrix semiconducting components were calculated from the absorbance spectra. The effect of the phase composition, UV irradiation duration, the nature and quantity of the activator (H2C2O4 and H2O2) on the degree of oxidation destruction was investigated. The best catalytic performance (98–99 % DCF degradation) was achieved with the combination of heterogeneous boron nitride and SiAlON based composites and a homogeneous photo‐Fenton system. However, DCF decomposition with a minimum number of intermediates was achieved using boron nitride‐based composites. Effective degradation of diclofenac in water! Iron‐containing composites capable of absorbing UV radiation and creating conditions in the presence of hydrogen peroxide and oxalic acid for homogeneous photocatalysis are proposed. Deep degradation occurs with simultaneous oxidative destruction processes of diclofenac according to the principle of heterogeneous and homogeneous photocatalysis

Challenges in the Greener Production of Formates/Formic Acid, Methanol, and DME by Heterogeneously Catalyzed CO2 Hydrogenation Processes

The recent advances in the development of heterogeneous catalysts and processes for the direct hydrogenation of CO2 to formate/formic acid, methanol, and dimethyl ether are thoroughly reviewed, with special emphasis on thermodynamics and catalyst design considerations. After introducing the main motivation for the development of such processes, we first summarize the most important aspects of CO2 capture and green routes to produce H2. Once the scene in terms of feedstocks is introduced, we carefully summarize the state of the art in the development of heterogeneous catalysts for these important hydrogenation reactions. Finally, in an attempt to give an order of magnitude regarding CO2 valorization, we critically assess economical aspects of the production of methanol and DME and outline future research and development directions

Cover picture: Shaping covalent triazine frameworks for the hydrogenation of Carbon Dioxide to Formic Acid (ChemCatChem 13/2016)

The Front Cover shows a formation of covalent triazine framework (CTF) based spheres using commercially available polyimide as a binder. In their Full Paper, A. V. Bavykina et al. present a facile one‐step method to shape CTFs into composite spheres with accessible porosity, high mechanical, and thermal stability. They used the fabricated spheres to host organometallic IrIII complex and obtained a catalyst, which is active and fully recyclable in the direct hydrogenation of carbon dioxide into formic acid.

Turning a Methanation Catalyst into a Methanol Producer: In-Co Catalysts for the Direct Hydrogenation of CO2 to Methanol

The direct hydrogenation of CO2 to methanol using green hydrogen is regarded as a potential technology to reduce greenhouse gas emissions and the dependence on fossil fuels. For this technology to become feasible, highly selective and productive catalysts that can operate under a wide range of reaction conditions near thermodynamic conversion are required. Here, we demonstrate that indium in close contact with cobalt catalyses the formation of methanol from CO2 with high selectivity (>80%) and productivity (0.86 gCH3OH.gcatalyst-1.h-1) at conversion levels close to thermodynamic equilibrium, even at temperatures as high as 300 °C and at moderate pressures (50 bar). The studied In@Co system, obtained via co- precipitation, undergoes in situ transformation under the reaction conditions to form the active phase. Extensive characterization demonstrates that the active catalyst is composed of a mixed metal carbide (Co3InC0.75), indium oxide (In2O3) and metallic Co. </div

Oxidative Coupling of Methane over MOF-Mediated La₂O₃

Due to the recent increase in natural gas reservoir discoveries, where methane is the main constituent, research into the upgrading of methane is gaining more attention. Among the techniques being explored, Oxidative Coupling of Methane (OCM) is one of the most promising routes for on-purpose ethylene production. OCM requires an efficient catalyst to achieve high C2+ selectivity, and lanthanum oxide has long been known to be a promising catalyst for this reaction. However, it is well-known that the synthesis method for OCM catalysts plays an important role in the performance of materials like La2O3 for this reaction. Herein, we report the catalytic performance of La2O3 prepared through the use of an inexpensive La-based-Metal Organic Framework (La-MOF) and compare its activity to a conventionally prepared La2O3 via sol–gel (La-SG) and an off-the-shelf commercial La2O3 (La-C). All three catalysts exhibit the hexagonal crystal structure of La2O3. The catalytic tests were carried out between 600 and 800 °C using different feed ratios (methane to oxygen) ranging between 3.5 and 13. Among these three catalysts, La-MOF exhibits the smallest particle size of 220 nm versus 350 and 1140 nm for La-SG and La-C, respectively. XPS results suggest the formation of different surface species on the catalyst’s surface which can influence the selectivity and catalytic results at 800 °C for a methane to oxygen ratio of 3.5 showing that the C2+ yield for La-MOF was approximately 15.8%–higher than 11.75% and 9.5% for La-SG and La-C, respectively
