Shear‐strained Pd Single‐atom Electrocatalysts for Nitrate Reduction to Ammonia

Angewandte Chemie, Год журнала: 2024, Номер 136(43)

Опубликована: Июль 16, 2024

Abstract Electrochemical nitrate reduction method (NitRR) is a low‐carbon, environmentally friendly, and efficient for synthesizing ammonia, which has received widespread attention in recent years. Copper‐based catalysts have leading edge due to their good adsorption of *NO 3 . However, the formation active hydrogen (*H) on Cu surfaces difficult insufficient, resulting large amount by‐product NO 2 − In this work, Pd single atoms suspended interlayer unsaturated bonds CuO formed dislocations (Pd−CuO) were prepared by low temperature treatment, located subjected shear stress dynamic effect support promote conversion into ammonia. The catalysis had an ammonia yield 4.2 mol. g cat −1 h , Faraday efficiency 90 % production at −0.5 V vs. RHE. situ characterization theoretical calculations indicate that effects carriers under obviously hydrogen, reduce reaction energy barrier decision‐making step further generation.

Siderophore-Mediated Cooperation in Anammox Consortia

Environmental Science & Technology, Год журнала: 2025, Номер unknown

Опубликована: Фев. 17, 2025

It has been widely accepted that iron plays an important role in stimulating the activity of anammox bacteria, which contain many clusters for electron transport cells. However, whether bacteria could directly use and how to uptake Fe(III) have long-time ignored. Here, we found micrometer-scale magnetite with size 10–20 μm significantly promoted bacterial by core uptake. Anammox cannot utilize as they are unable secrete siderophore extracellular transfer intracellular. In anaerobic consortia at presence magnetite, synthesis belonging Alphaproteobacteria, Candidate phylum, Chloroflexi secreted abundant siderophores, combined ionized from form siderophore-Fe(III) complexes. These complexes were then used via a specific outer membrane receptor transported transporter protein periplasm, further releasing Fe(III). Cytochrome c was formed complex reduction, assimilation Fe–S heme B increase capability. This study reveals siderophore-mediated cooperation implies driving nitrogen conversion artificial or natural system.
