Mashup Score: 0Coupling nitrate capture with ammonia production through bifunctional redox-electrodes - Nature Communications - 1 year(s) ago
Coupling nitrate capture with conversion to ammonium is attractive because it combines pollutant remediation and chemical production. Here, the authors design a bifunctional redox-electrode to achieve the reactive separation of nitrate to ammonium in a single electrochemical cell.

The development of a nitrogen fixation process that relies on the renewable energy, such as visible light, is an important goal in sustainable chemistry. Here, authors establish an iridium and molybdenum-catalysed ammonia formation from dinitrogen driven by visible light under ambient reaction conditions.

Mashup Score: 7Boosting electrocatalytic CO2–to–ethanol production via asymmetric C–C coupling - Nature Communications - 2 year(s) ago
It is of high interest to convert CO2 into valuable ethanol product. Here the authors demonstrate the asymmetric C-C coupling triggered on Ag-modified oxide-derived Cu sites can accelerate and steer the reaction pathway for ethanol production with high faradaic efficiency and current density.

Mashup Score: 1Hydroxyl radicals dominate reoxidation of oxide-derived Cu in electrochemical CO2 reduction - Nature Communications - 2 year(s) ago
The Cuδ+ species has been frequently detected during CO2 reduction and plays a key role in C-C coupling for C2+ products. Here the authors uncover that the HCO3- solution can activate hydroxyl radicals that oxidize metallic Cu to surface Cuδ+ species.

Mashup Score: 1
Single-atom catalysts (SACs) are widespread in academic literature. From synthesis to applications, the development and growth of research on SACs has been exponential in the last decade. However, determining the major issues of the field and the milestones for SACs to become a major player in industry or to reach decarbonization goals are still not easily realized. There is a “turning point” in…

Mashup Score: 2Electrochemical oxygen reduction to hydrogen peroxide at practical rates in strong acidic media - Nature Communications - 2 year(s) ago
Electrochemical oxygen reduction to H2O2 in acidic media suffers from low selectivity, especially at high current densities. Here, the authors report a cation-regulated “shielding effect” to promote the H2O2 selectivity under industrial-relevant current in strong acid.

Mashup Score: 2Pseudo-adsorption and long-range redox coupling during oxygen reduction reaction on single atom electrocatalyst - Nature Communications - 2 year(s) ago
The reaction region is commonly considered to be the direct catalyst surface. Here, the authors challenge this view and use molecular dynamics simulations to reveal a solvated hydroxide species dynamically confined in a pseudo-adsorption state at a few water layers away from the active site during oxygen reduction reaction on single atom electrocatalyst.

Mashup Score: 2
Metal-organic frameworks are promising catalysts for CO2 electroreduction, yet limited by their poor conductivity and stability. Here, Au nanoneedles are inserted into the metalloporphyrin framework to activate C-C coupling and stabilize the structure for much enhanced ethylene production.
