Mixed Matrix Pt-Carbon Nanofiber Polyethersulfone Catalytic Membranes for Glucose Dehydrogenation.

The advancement of technologies for producing chemicals and materials from non-fossil resources is of critical importance. An illustrative example is the dehydrogenation of glucose, to yield gluconic acid, a specialty chemical. In this study, we propose an innovative production route for gluconic acid while generating H as a co-product.

Cinnamaldehyde hydrogenation over carbon supported molybdenum and tungsten carbide catalysts.

The potential of carbon supported Mo and W carbides to replace Pt is shown for the hydrogenation of cinnamaldehyde. Although the carbide catalysts are 4-6 times less active, both the carbides and Pt are selective towards CC hydrogenation. Unlike Pt, the carbides additionally form β-methylstyrene.

Shedding Light on Solid Sorbents: Evaluation of Supported Potassium Carbonate Particle Size and Its Effect on CO Capture from Air.

Solid sorbents are essential for developing technologies that directly capture CO from air. In solid sorbents, metal oxides and/or alkali metal carbonates such as potassium carbonate (KCO) are promising active components owing to their high thermal stability, low cost, and ability to chemisorb the CO present at low concentrations in air. However, this chemisorption process is likely limited by internal diffusion of CO into the bulk of KCO.
