  • Converting CS2 and COS pollutants into benign products is critical in eliminating waste exhaust fumes. Now, a series of air-stable palladium complexes mediate hydrolysis of both CS2 carbon–sulfur bonds at 25 °C to produce CO2. Oxidation of the resulting complexes regenerates the starting complexes with SO2 and NO2 release.

  • Methane borylation allows for the functionalization of an otherwise unreactive compound, enabling its use as a one-carbon building block; however, competing diborylation presents a selectivity issue. Now, a metal–organic-framework-based catalyst highly selective for monoborylation is reported. The selectivity is due to the reaction taking place within the catalyst pores, which excludes the formation of the larger diborlyated product.

  • Selective pyridine dearomatization processes traditionally use precious metal catalysts with reagents in stoichiometric excess, and are not well-understood mechanistically. Now, efficient 1,2-regioselective pyridine dearomatization is achieved using equimolar pinacolborane and an earth-abundant lanthanide catalyst. Mechanistic and theoretical studies elucidate the reaction mechanism and explain observed reactivity trends.

  • The cleavage of C–C bonds in hydrocarbons is traditionally entrusted to precious metal catalysts, whereas common non-reducible oxides are considered unreactive. Now, the authors report nanostructured silica-embedded zirconia nanoparticles that are competent for the hydrogenolysis of polyethylene with remarkable performance.

  • Achieving plastic deconstruction with high selectivity is crucial for upcycling schemes, but remains challenging. Here, a processive approach for the selective hydrogenolysis of high-density polyethylene into narrow alkane fractions is introduced relying on a Pt/SiO2 catalyst encapsulated in a mesoporous silica shell.

  • TiO2 and other metal oxides were interfaced with molecular boron clusters to form a hybrid material. This modifies the electrochemical and photocatalytic properties, enabling fast electron transfer and dye degradation under red light.
