Electrochemistry of outer-sphere redox molecules involves an essentially intact primary coordination sphere with minimal secondary adjustments, resulting in very fast electron transfer events even without a noble metal-based electrocatalyst. Departing from conventional electrocatalytic paradigms, we incorporate these reaction coordinate adjustments species to stimulate the electrocatalysis energetically challenging inner-sphere substrates. Through this approach, are able show intricate 8e

Abstract The efficiency of nitrate reduction reaction (NO 3 RR) at low concentration is predominantly hindered by the poor affinity ions and competitive hydrogen evolution (HER), particularly in neutral acidic media. Here, an innovative strategy to leverage interfacial electric field (IEF) introduced boost NO RR performance. By situ constructing tannic acid‐metal ion (TA‐M 2+ ) crosslinked structure on electrode surface, TA‐M ‐CuO NW/Cu foam sample exhibits exceptional Faraday 99.4% −0.2 V versus reversible (RHE) 83.9% 0.0 RHE under conditions, respectively. computational studies unveil that TA‐Cu complex CuO (111) plane induces increasing interface, accelerating kinetics over HER via IEF effect. This modulation also contributes enhanced ammonia production performance when it employed commercial materials flow reactors, exhibiting great potential practical application. Overall, combined results illustrated multiple merits effect, paving way for future commercialization industry.

Abstract In this work we describe the use of bimetallic silver‐copper macroporous foams for electrochemical nitrate reduction in acidic conditions (pH 2, 0.1 M NaClO 4 ). By carefully selecting composition electrodeposition bath, have successfully prepared with atomic percentage varying from Ag dominant to Cu dominant. Also, succeeded obtain morphologies that vary between one specific pure foam foam. We shown these contain a silver phase and also alloy. The active surface area depends both on morphology as well composition. These materials were used first time catalysts reaction (NO 3 RR). Both liquid gaseous products quantified several analytical techniques. It was present superior faradaic efficiency (FE) towards comparisons copper foams, suggesting synergetic contribution metals. 94 6 (AgCu10) shows FE high 92 % lowest (3 %) undesired product, i. e. nitrous acid. material better stability than presence conditions.
