Catalysis

Definition

Catalysis is the increase in the rate of a chemical reaction by the addition of a reagent — the catalyst — that is not itself consumed. The catalyst works by opening up a route between starting material and product with a lower activation barrier than the uncatalyzed process.

    The efficiencies of materials-based catalysts are determined by the surface atomic and electronic structures, but harnessing this relationship can be challenging. Here, by engineering strain into cobalt oxide, the authors transform a once poor hydrogen evolution catalyst into one that is competitive with the state of the art.

    Within natural product biosynthetic pathways, nature has evolved highly selective catalysts capable of complexity generating reactions. Leveraging these tools, a suite of catalysts with complementary site- and stereoselectivity have been applied to the oxidative dearomatization of phenolic compounds, enabling one-pot transformations of phenols into various natural products.

    Hydrogen is mainly produced industrially via steam methane reforming, a multistage process carried out in large plants to minimize energy losses and costs. Here, by exploiting thermal integration in a protonic membrane reformer, the authors produce compressed hydrogen in a single step with high efficiency.

    Photochemical synthesis is a popular approach to fabricate metallic nanoparticles, however stabilizing individually-dispersed atoms by this method remains challenging. Here, the authors freeze their precursor solution prior to UV irradiation to obtain atomically-dispersed platinum catalysts with high electrocatalytic performance.

    Investigating unusual organometallic pathways may help to efficiently control product selectivity in homogeneous catalysis. Here, the authors report the hydroarylation of aromatic amides with norbornene derivatives and propose the formation of a rhodium-carbene intermediate leading to rarely observed endo-products.
