Abstract Electrocatalytic nitrate reduction reaction (NO 3 RR) toward ammonia synthesis is recognized as a sustainable strategy to balance the global nitrogen cycle. However, it still remains great challenge achieve highly efficient production due complex proton‐coupled electron transfer process in NO RR. Here, controlled of RuMo alloy nanoflowers (NFs) with unconventional face‐centered cubic (fcc) phase and hexagonal close‐packed/fcc heterophase for RR reported. Significantly, fcc NFs demonstrate high Faradaic efficiency 95.2% large yield rate 32.7 mg h −1 cat at 0 −0.1 V (vs reversible hydrogen electrode), respectively. In situ characterizations theoretical calculations have unraveled that possess highest d‐band center superior electroactivity, which originates from strong Ru─Mo interactions intrinsic activity phase. The optimal electronic structures supply adsorption key intermediates suppression competitive evolution, further determines remarkable performance. successful demonstration high‐performance zinc‐nitrate batteries suggests their substantial application potential electrochemical energy systems.

Photoelectrochemical Nitrate and Nitrite Reduction Using Cu₂O Photocathodes

ACS Energy Letters, Год журнала: 2024, Номер 9(5), С. 1993 - 1999

Опубликована: Апрель 4, 2024

Nitrate in wastewater streams causes eutrophication, and nitrate removal is of great importance for environmental protection. Electrochemical reduction has the advantage directly converting to benign or useful chemicals, but it typically requires a considerable overpotential. In this study, photoelectrochemical investigated using Cu2O photocathode, where photoexcited electrons conduction band inherently have an overpotential >1.6 V reduction. The photocathode found reduce nitrite selectively with high Faradaic efficiency (>85%). More importantly, as surface particularly catalytic reduction, on kinetically suppresses photocorrosion without need additional catalyst protection layers. addition examined compare effects kinetics photocurrent generation photocathodes.
