Substrate crystallinity governs the binding-activity trade-off in cellulases The enzymatic deconstruction of plant biomass might become vital to the sustainable production of fuels and materials, and cellulases are the most important enzymes for this purpose. The current work uses a large kinetic dataset to explore the nature of the transition state (TS) of cellulases. We report that the activation barrier reflects changes in non-covalent interactions during the association and dissociation steps and sketch the approximate structures of the associated TSs. These TSs depend strongly on substrate crystallinity.

Early transition metal Cu-based single-atom alloys for selective propane dehydrogenation to propylene This work reveals that incorporating early transition metals into Cu(111) forms highly promising catalysts for selective propane dehydrogenation. Not only are they more selective, but they are also more active than the conventional Pt catalysts. This superior reactivity stems from the depletion of anti-bonding orbitals between the active atom and the rate-limiting transition state, weakening unfavorable interactions. This unique electronic effect, combined with the inherent geometric constraints that inhibit undesired side reactions, makes them an excellent alternative for this reaction.

Substrate-induced redox reconstruction of nickel sites in organic oxidation #electrocatalysis We present Ni12P5 nanostructures as an efficient (pre)catalyst in alkaline media. They transform into Ni(III/IV) oxyhydroxides under OER conditions but revert to Ni(II) active states in the presence of HMF or AmTET. Quasi in situ XAS, along with in situ Raman, confirms this reversible redox shift, highlighting their robustness and adaptability.

#catalytic strategies and mechanisms for enhancing MgH2 solid-state hydrogen storage MgH2 offers high hydrogen capacity but suffers from sluggish, surface-controlled dehydrogenation. This perspective highlights the “burst effect,” where the first surface dehydrogenation step is the main kinetic bottleneck, and uses it as a unifying framework to reinterpret #catalytic strategies, atomistic mechanisms, and theory-guided design. By linking surface chemistry to macroscopic kinetics, it outlines practical directions for catalyst development, descriptor discovery, and data-driven inverse design in solid-state hydrogen storage.

Molecular trick to reverse SN2 step in a haloalkane dehalogenase Haloalkane dehalogenases catalyze an SN2 nucleophilic substitution to erase halogen substituents in organohalogen compounds. The acid-base-nucleophile triad secures irreversible SN2 displacement of the halogen for the hydroxyl derived from the water. In this report, we elucidate a molecular basis for how this originally irreversible SN2 process becomes fully reversible in a histidine-to-phenylalanine mutant, favoring a transhalogenation chemistry. This offers a greener alternative for industrial transhalogenation processes, applicable in the recycling of environmentally harmful halogenated compounds.

Bayesian optimization guides the discovery of high-performance catalysts for direct CO2-to-jet-fuel conversion Bayesian optimization was used to guide the discovery of an unconventional CO2 Fischer-Tropsch catalyst selective to jet-fuel-range hydrocarbons. The Fe1Cu1.8K0.01 catalyst achieved the highest C5+ yield reported for CO2-FT, with more than 70% of the liquid product in the jet-fuel range and stable composition over extended operation. After upgrading, the CO2-derived liquid shows strong potential for blending into conventional jet fuel.

Electricity-driven plasma-thermocatalytic cascade for direct nitrogen fertilizer production from air and water To address the environmental challenges of conventional nitrogen fertilizer production, a fully electricity-driven plasma-thermal #catalytic cascade is proposed for NH4NO3 synthesis from air and water. N2 (from air) and water vapor are activated in a plasma discharge to generate NOx and H2, with a portion of NO converted to NH3 via thermocatalytic hydrogenation. The remaining NOx and the generated NH3 are co-absorbed in the presence of O2 to form an aqueous NH4NO3 solution, enabling nitrogen fertilizer production without fossil fuels.

Spin effects in CO methanation over promoted Ni catalysts Magnetism can directly influence how catalysts work. In CO methanation on Ni catalysts, promoter metals enhance activity by suppressing the surface magnetic moment, strengthening key intermediate binding and lowering bond-breaking barriers. The binding enhancement scales with spin reduction, and new reaction pathways become accessible. This study introduces spin-state engineering as a practical strategy for tuning the activity and mechanism in magnetic metal catalysts.
