Flower-like open-structured polycrystalline copper with synergistic multi-crystal plane for efficient electrocatalytic reduction of nitrate to ammonia

Oxygen vacancies in Co3O4nanoarrays promote nitrate electroreduction for ammonia synthesis

“…[13][14][15] Nitrate (NO 3 À ), a NO x species harmful to the ecosystem and organisms, widely exists in industrial/domestic sewage and groundwater. [16][17][18] Unlike N 2 , it has a N]O bond with a relatively low cleavage energy of 204 kJ mol À1 , 17 revealing its active chemical properties. In addition, NO 3…”

Co Nanoparticles Decorated Corncob-Derived Biomass Carbon as an Efficient Electrocatalyst for Nitrate Reduction to Ammonia

“…Nitrate (NO 3 – ) is one of the most harmful contaminants in aqueous systems, and it has become a global problem due to its high solubility and mobility. , Given that NO 3 – is highly water-soluble and more easily activated than N 2 , the preparation of NH 3 by electrochemical NO 3 – reduction reaction (NO 3 RR) can serve as a more potential substitute to the HBP than to the NRR. − Furthermore, the NO 3 RR can not only synthesize highly value-added NH 3 to help alleviate the energy crisis but also purify polluted water. However, NH 3 production by electrocatalytic NO 3 RR is a very complex process involving various intermediates and byproducts. − Thus, it is urgent to exploit highly active and selective NO 3 RR electrocatalysts for sustainable NH 3 production.…”

High-Efficiency Electrosynthesis of Ammonia with Selective Reduction of Nitrate in Neutral Media Enabled by Self-Supported Mn2CoO4 Nanoarray

“…However, since the eNO 3 RR to NH 3 is very complex, many reaction pathways and various intermediates (NO 2 H, OH, NOH 3 , NH 3 , NO 2 – , N, NOH 2 , NO, N 2 O, etc.) are involved. − It is thus urgent to develop highly efficient and active electrocatalysts for the selective reduction of NO 3 – to NH 3 .…”
