Heterogeneous catalysis articles from across Nature Portfolio

The dynamic transformation of Cu ions during the selective catalytic reduction of NO_x on Cu zeolites is well documented, although the function of the zeolite framework has not been fully understood. Here the authors unravel the role of anionic Al sites in the zeolite framework in regulating the mobility and reactivity of Cu cations during catalysis.

The reaction efficiency of reactants near plasmonic nanostructures can be enhanced under illumination. Here, the authors show that the activity of a Co porphyrin molecular catalyst bound to Au nanoparticles is enhanced by plasmonic effects, yielding a high photocatalytic hydrogen generation rate.

The working temperature of boron-based catalysts reduces their thermodynamic advantages in the oxidative dehydrogenation of propane (ODHP). Here the authors demonstrate encapsulated Ni nanoparticles as effective subsurface promoters to enhance the low temperature activity and selectivity of the boron oxide overlayer in ODHP.

The development of heterogeneous metallaphotocatalysis is of great interest for sustainable organic synthesis. Herein, the authors demonstrate the incorporation of privileged homogeneous bipyridyl-based Ni-catalysts into highly ordered and crystalline potassium poly(heptazine imide) (K-PHI).

To overcome mass transport limitations in zeolite-catalysed reactions, scientists must often resort to hierarchical or nanosized zeolites; however, the synthesis of such materials remains challenging. Here the authors disclose a one-pot method for the preparation of Si-zoned MFI-type catalysts with improved diffusion properties for the methanol-to hydrocarbon reaction.

Polar functional groups can improve the polymer properties of polyolefins but also poison the metal catalyst used during the polymerization reaction. Here, the authors show that functionalized bimodal polyolefins in which the high-molecular-weight fraction bears few functional groups and possesses high mechanical and melt properties can be used to implement both polarity and processability
