Abstract Mother nature accomplishes efficient ammonia synthesis via cascade N 2 oxidation by lightning strikes followed with enzyme‐catalyzed nitrogen oxyanion (NO x − , = 2,3) reduction. The protein environment of enzymatic centers for NO ‐to‐NH 4 + process greatly inspires the design glutathione‐capped (GSH) quantum dots (QDs) under visible light (440 nm) in tandem plasma‐enabled oxidation. Mechanistic studies reveal that GSH induces positive shift surface charge to strengthen interaction between and QDs. Upon irradiation QDs, balanced rapid hole electron transfer furnish GS·radicals 2e /2H alcohol H·for 8e /10H 3 reduction simultaneously. For first time, mmol‐scale is realized apparent yields 5.45% ± 0.64%, gram‐scale value‐added acetophenone NH Cl proceeds 1:4 stoichiometry stability, demonstrating promising multielectron multiproton efficiency sustainability nature‐inspired artificial photocatalysts.

Natural nitrogen cycle has been severely disrupted by anthropogenic activities. The overuse of N-containing fertilizers induces the increase nitrate level in surface and ground waters, substantial emission oxides causes heavy air pollution. Nitrogen gas, as main component air, used for mass ammonia production over a century, providing enough nutrition agriculture to support world population increase. In last decade, researchers have made great efforts develop processes under ambient conditions combat intensive energy consumption high carbon associated with Haber-Bosch process.

Electrochemical nitrate reduction reaction (NO 3 RR) to ammonia has been regarded as a promising strategy balance the global nitrogen cycle. However, it still suffers from poor Faradaic efficiency (FE) and limited yield rate for production on heterogeneous electrocatalysts, especially in neutral solutions. Herein, we report one-pot synthesis of ultrathin nanosheet-assembled RuFe nanoflowers with low-coordinated Ru sites enhance NO RR performances electrolyte. Significantly, exhibit outstanding FE 92.9% 38.68 mg h −1 cat (64.47 ) at −0.30 −0.65 V (vs. reversible hydrogen electrode), respectively. Experimental studies theoretical calculations reveal that are highly electroactive an increased d-band center guarantee efficient electron transfer, leading low energy barriers reduction. The demonstration rechargeable zinc-nitrate batteries large-specific capacity using indicates their great potential next-generation electrochemical systems.

Abstract The controlled synthesis of metal nanomaterials with unconventional phases is significant importance to develop high‐performance catalysts for various applications. However, it remains challenging modulate the atomic arrangements nanomaterials, especially alloy nanostructures that involve different metals distinct redox potentials. Here we report general one‐pot IrNi, IrRhNi and IrFeNi nanobranches hexagonal close‐packed (hcp) phase. Notably, as‐synthesized hcp IrNi demonstrate excellent catalytic performance towards electrochemical nitrite reduction reaction (NO 2 RR), superior NH 3 Faradaic efficiency yield rate 98.2 % 34.6 mg h −1 cat (75.5 Ir ) at 0 −0.1 V (vs reversible hydrogen electrode), respectively. Ex/in situ characterizations theoretical calculations reveal Ir−Ni interactions within improve electron transfer benefit both activation active generation, leading a stronger trend NO RR by greatly reducing energy barriers rate‐determining step.
