Constructing active sites with specific designs is highly desired and challenging to achieve with high activity and selectivity of photoreduction. Herein, our studies find that a series of Bi-based materials with different compositions, …Development of heterogeneous catalysts for alcohol transformation into nitriles under oxidant-free conditions is a challenge. Considering the C–H activation on α-carbon of primary alcohols is the rate-determining step, decreasing the activation energy of C–H activation is critical in order to enhance the catalytic activity. Several NiM/Al2O3 …Transaminases show potential for the industrial synthesis of important pharmaceutical ingredients.

Glycosyltransferases (GTs) catalyze the formation of glycosidic bonds in carbohydrates and glycoconjugates, with various outcomes depending not only on the acceptor molecules they bind but also on the type of glycosidic bond they form (C–O, C–N, C–S, or C–C). Here we show that the glucosyltransferase UGT1 from the indigo plant …Fischer–Tropsch synthesis (FTS) is a significant catalytic process for the production of liquid fuel and fine chemicals from natural gas-, coal-, and biomass-derived syngas.
