Enhanced Activity and Stability for Electrocatalytic Nitrate Reduction to Ammonia over Low‐Coordinated Cobalt

Small, Год журнала: 2025, Номер unknown

Опубликована: Янв. 31, 2025

It is still challenging to develop an effective strategy simultaneously enhance the activity and stability of electrocatalysts for electrocatalytic nitrate reduction reaction (eNO3RR). Herein, taking metallic cobalt as example, it demonstrated that construction low-coordinated nanosheets (L-Co NSs) by H2 plasma etching electrodeposited (Co can greatly eNO3RR. Compared with Co NSs, at -0.4 V versus RHE, removal rate, ammonia partial current density, yield are increased L-Co NSs from 82.14% 98.57%, 476 683 mA cm-2, 2.11 2.54 mmol h-1 respectively. In addition, demonstrate negligible decay after 30 cycles test, while show significant decline. situ electrochemical characterizations theoretical calculations verify abundance vacancies in not only contribute optimized electronic structure enhanced desorption key intermediate boost but also facilitate transformation Co(OH)2 Co0 promote stability. Furthermore, exhibit favorable performance removing simulated wastewater air discharge-electrocatalytic cascade system produce ammonia.

Integrating biocatalysis with nanophotocatalysis provides a promising pathway to address the knotty environmental and energy problems. However, loss during transfer of extracellular electrons across nano-bio interface seriously limits efficiency whole-cell-based photobiocatalytic systems. Herein, we demonstrate an integrated multienergy codriven reaction platform containing BaTiO3 nanoparticles (BTO) for harvesting mechanical from flowing water elevate interfacial electric field, BiVO4 quantum dots (BQD) light generate photocarriers, Geobacter sulfurreducens (GS) accepting photoelectrons accomplish biocatalytic reactions. The synergism between piezoelectric photoelectric fields significantly promotes cross-membrane transport photoelectrons, contributing enhanced acetate metabolism, electron transfer, synthesis GS microbes. Such well-designed BQD/BTO-GS hybrids result in simultaneous degradation organic contaminants detoxification heavy metals approximately 100% treatment efficiency. rates tetracycline (TC) oxidation Cr(VI) reduction are determined be 32.8 9.58 times higher than that biocatalysis, respectively. Our exhibits exceptional apparent yield 15.54% at 400 nm, exceeding those most reported abiotic–biotic Further investigation verifies extensibility our strategy other enhancing efficiencies (such as methanogenesis, CO2 fixation, denitrification), thus offering inspiring applications. This work not only presents crucial insights into mechanism water-energy nexus but also paradigm construction sustainable systems via harnessing.
