Heterointerface-Enhanced Active Hydrogen Generation in Ru/RuOx/CNTs for Nitrate Reduction to Ammonia at Low Overpotentials.

Ru/RuOx/CNTs heterostructured materials are synthesized using an in situ method. The Ru─RuOx heterostructure facilitates active hydrogen dissociation, leading to excellent catalytic performance in nitrate reduction, with ammonia as the primary product at low overpotentials. The process achieves Faradaic efficiencies of ammonia exceeding 90% and a production rate of 1.

Electrochemical Reversible Reforming between Ethylamine and Acetonitrile on Heterostructured Pd-Ni(OH) Nanosheets.

Rational design of electrocatalysts is essential to achieve desirable performance of electrochemical synthesis process. Heterostructured catalysts have thus attracted widespread attention due to their multifunctional intrinsic properties, and diverse catalytic applications with corresponding outstanding activities. Here, we report an in situ restoration strategy for the synthesis of ultrathin Pd-Ni(OH) nanosheets.

Ammonia-assisted synthesis of low-crystalline FeCo hydroxides for efficient electrochemical overall water splitting.

Low-crystalline FeCo hydroxides were synthesized on a gram scale with the aid of ammonia, and they exhibited impressive catalytic activity for both the HER and OER. We utilized these catalysts to assemble a water splitting cell, which functions efficiently. The electrolytic cell can produce a consistent current density of 200 mA cm for over 20 hours while operating at a voltage of 1.

Mesoporous PtPb Nanosheets as Efficient Electrocatalysts for Hydrogen Evolution and Ethanol Oxidation.

Using a one-pot hydrothermal method with ethylenediamine, we have synthesized mesoporous PtPb nanosheets that exhibit exceptional activity in both hydrogen evolution and ethanol oxidation. The resulting PtPb nanosheets have a Pt-enriched structure with up to 80 % atomic content of Pt. The synthetic method generated a significant mesoporous structure, formed through the dissolution of Pb species.

Heterostructured Ru/Ni(OH) Nanomaterials as Multifunctional Electrocatalysts for Selective Reforming of Ethanol.

The electrochemical reforming of ethanol into hydrogen and hydrocarbons can reduce the electric potential energy barrier of hydrogen production from electrochemical water splitting, obtaining high value-added anode products. In this work, Ru/Ni(OH) heterostructured nanomaterials were synthesized successfully by an reduction strategy with remarkable multifunctional catalytic properties. In the hydrogen evolution reaction, Ru/Ni(OH) exhibits a smaller overpotential of 31 mV to obtain a current density of 10 mA/cm, which is better than that of commercial Pt/C.
