Catalytic Kinetics Regulation for Enhanced Electrochemical Nitrogen Oxidation by Ru-Nanoclusters-Coupled Mn3O4 Catalysts Decorated with Atomically Dispersed Ru Atoms

Zhongfen Nie et al.

Summary: In this study, Ru-nanoclusters-coupled Mn3O4 catalysts were designed and explored for ambient N-2 oxidation, showing excellent catalytic performance. Both experiments and theoretical calculations reveal that the presence of Ru clusters and single-atom Ru is the reason for the outstanding activity, which effectively activates the chemically inert N-2 in synergy with Mn3O4.

Electrosynthesis of Nitrate via the Oxidation of Nitrogen on Tensile-Strained Palladium Porous Nanosheets

Shuhe Han et al.

Summary: Nitrate is an essential raw material in agriculture and industry, but the electrochemical nitrogen oxidation reaction (NOR) shows potential to replace traditional nitrate synthesis with high energy consumption and greenhouse gas emissions. Tensile-strained palladium porous nanosheets (Pd-s PNSs) were found to have enhanced activity for electrochemical NOR, outperforming Pd nanosheets. Experiments with N-15 isotope labeling confirmed that nitrate originates from nitrogen oxidation.

Tip-Enhanced Electric Field: A New Mechanism Promoting Mass Transfer in Oxygen Evolution Reactions

Peng Liu et al.

Summary: In this study, NiFe alloy nanocone arrays were used to enhance the oxygen evolution reaction (OER) rate and outperform state-of-the-art OER electrocatalysts. The high-curvature tips on the nanocones induce a local electric field that significantly increases the concentration of hydroxide ions near the active sites, promoting OER activity. This local field enhanced OER kinetics is suggested to be a generic effect applicable to other OER catalysts.

Ru-Doped Pd Nanoparticles for Nitrogen Electrooxidation to Nitrate

Tieliang Li et al.

Summary: In this study, Ru-doped Pd materials were prepared for electrocatalytic nitrogen oxidation, with the optimized Pd0.9Ru0.1 sample showing superior performance over pure Pd and Ru. Experimental and theoretical simulations indicate that Ru doping promotes the formation of more active species and changes the potential-limiting step with a lower energy barrier.

Constructing the Support as a Microreactor and Regenerator for Highly Active and In Situ Regenerative Hydrogenation Catalyst

Guoqiang Zhao et al.

Summary: This study introduces a hierarchically ordered porous poly(2,6-diaminopyridine) (PDAP) as a Pd nanoparticle support for hydrogenation removal of recalcitrant pollutants in water purification. The PDAP support acts as a sorbent and microreactor to enhance the proximity of targeted water pollutants and reactive hydrogen atom species, achieving unprecedently high water purification efficiency. The high activity and in situ regenerativity achieved by rational construction of the support structure sheds light on a new approach for designing efficient and robust heterogeneous hydrogenation catalysts.
