Spin‐State Modulation of Atomic Iron Sites Enables Efficient CO2 Electroreduction in Acid Medium

Angewandte Chemie, EarlyView.
An axial oxygen ligand was added to shift the spin state of the single‐atom Fe site from low to medium spin. This change reduces the interfacial interaction with H3O+ and decreases the *CO desorption energy, thus enhancing CO2RR in acidic media.

Characterization of gold nanoparticle layer deposited on gold electrode by various techniques for improved sensing abilities [PDF]

, 2016
The deposition of gold nanoparticles (AuNPs) on the surface of gold electrode is believed to enhance the electrochemical characteristics of the surface. According to the existing literature, this could be performed in various ways.

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

Advanced Energy Materials, EarlyView.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...

A simple method for detection of manganese in marine sediments [PDF]

, 1998
Microparticles of sediment are mechanically transferred to the graphite electrode surface and the presence of manganese oxyhydroxides is detected by square-wave voltammetry in 0.1 M oxalic acid. After preelectrolysis at -2 V vs. Ag/AgCl, a characteristic

Carboxylated Carbon Nanotube‐Supported Copper‐Indium Bimetallic Catalysts for Electroreduction of CO2 to Dimethyl Carbonate via Membrane‐Free Cascade Electrosynthesis

Carbon and Hydrogen, EarlyView.
A membrane‐free cascade electrocatalytic system with Cu100In50‐(COOH)CNTs converts CO2 to CO and then couples with alcohols to yield DMC (52.3% FE) and DEC (27.8% FE) via carboxyl‐Cu‐In synergistic regulation of intermediate adsorption. ABSTRACT Under the background of the dual carbon strategy, upgrading CO2 electroreduction from C1 products to high ...
