Catalysis

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 design of nanostructured catalysts plays a key role in the electrocatalytic redox reaction performances. Here, authors prepared uniform and small-sized high-entropy alloy PtNiFeCoCu nanoparticles that showed improved activities for H2 evolution methanol oxidation reactions.

    The spatial segregation of distinct catalytic functionalities within the same material holds great promise for cascade or antagonistic reactions, but it remains challenging. Here, the authors report the successful realization of this approach for an efficient hierarchical porous silica catalyst featuring spatially separated sulfated zirconia and magnesium oxide.

    Synthetic methods aiming at minimizing reaction steps while increasing molecular complexity are highly sought after by organic chemists. Here, the authors report two cascade procedures combining nucleophilic substitution, palladium-catalyzed Heck and C–H activation reactions for the synthesis of spiro-fused heterocycles.

    Chiral aldehyde catalysis is a useful strategy in the catalytic asymmetric α-functionalization of amino methyl compounds but these reaction types are limited. Here, the authors report two chiral aldehyde-catalysed diastereodivergent reactions, namely, a 1,6-conjugate addition and a bio-inspired Mannich reaction.
