The electrochemical nitrate reduction reaction (NO3RR) is an attractive green alternative to the conventional Haber-Bosch method for synthesis of NH3. However, this a tandem process that involves multiple steps electrons and protons, posing significant challenge efficient Herein, we report high-rate NO3RR electrocatalyst Fe Cu double-doped Co3O4 nanorod (Fe1/Cu2-Co3O4) with abundant oxygen vacancies, where preferentially catalyzes rapid conversion NO3- NO2- vacancy in substrate can accelerate In addition, introduction efficiently capture atomic H* promotes dynamics NH3, improving Faradaic efficiency produced Controlled experimental results show optimal Fe1/Cu2-Co3O4 exhibits good performance high (93.39%), (98.15%), ammonia selectivity (98.19%), which significantly better than other Co-based materials. This work provides guidance rational design high-performance catalysts.

Ru-Doped Ultrasmall Cu Nanoparticles Decorated with Carbon for Electroreduction of Nitrate to Ammonia

Inorganic Chemistry, Год журнала: 2024, Номер 63(8), С. 3955 - 3961

Опубликована: Фев. 9, 2024

Electrocatalytic nitrate reduction reaction offers a sustainable approach to treating wastewater and synthesizing high-value ammonia under ambient conditions. However, electrocatalysts with low faradaic efficiency selectivity severely hinder the development of nitrate-to-ammonia conversion. Herein, Ru-doped ultrasmall copper nanoparticles loaded on carbon substrate (Cu-Ru@C) were fabricated by pyrolysis Cu-BTC metal-organic frameworks (MOFs). The [email protected] catalyst exhibits high (FE) 90.4% at -0.6 V (vs RHE) an yield rate 1700.36 μg h

The construction of photocatalysts with a surface plasmon resonance effect (SPR) has been demonstrated as highly effective strategy for enhancing photocatalytic efficiency. In this paper, we synthesized catalyst bismuth metal loaded on ZnCdS nanospheres an efficient nitrogen reduction reaction (PNRR). SPR induced by Bi nanoparticles under light excitation significantly promoted the ammonia production efficiency photocatalyst. Under air ambient conditions lactic acid sacrificial agent, NH4+ yield 3% Bi@ZnCdS was 58.93 μmol·g–1·h–1, which exhibited approximately 7.7 times that pure phase ZnCdS. experimental characterization results demonstrate incorporation metallic enhances absorption capacity and improves separation photogenerated carriers. Theoretical calculations proved NPs provide more electrons to convert N2 NH3 solid-solution This work presents novel concept development advanced plasma nanomaterials enhance fixation reaction.
