In recent years, electrochemical reduction of carbon dioxide (CO 2 ) has received a great deal of attention due to the potential that this process can mitigate the atmospheric CO 2 concentration and produce valuable organic compounds. In particular, Cu and Cu-based catalysts have exhibited the capability of converting CO 2 into multicarbon fuels and chemicals in significant quantities. Here, we report a facile and cheap fabrication method for the development of an Ag-incorporated cuprous oxide (

Electrocatalytic conversion of carbon dioxide (CO2) has recently received considerable attention as one of the most feasible CO2 utilization techniques. In particular, copper and copper-derived catalysts have exhibited the ability to produce a number of organic molecules from CO2. Herein, we report a chloride (Cl)-induced bi-phasic cuprous oxide (Cu2O) and metallic copper (Cu) electrode (Cu2OCl) as an efficient catalyst for the formation of high-carbon organic molecules by CO2 conversion, and id

The first method for achieving Hiyama couplings of unactivated alkyl bromides and iodides is reported. The desired carbon-carbon bond formation proceeds under mild conditions (room temperature) with good functional-group tolerance.

A basic understanding of electrode structure and the characteristics of its components can be powerfully utilized in fuel cell applications such as direct formic acid fuel cell (DFAFC) system integration and HCOOH concentration controlled systems. There have been, thus, tremendous efforts made to elucidate theoretical aspects of electrochemical processes involving new anode catalysts and put them into practical effect on formic acid fuel cells. Herein, we highlight recent studies for better unde

Abstract Electrocatalytic conversion of carbon dioxide (CO 2 ) has recently received considerable attention as one of the most feasible CO 2 utilization techniques. In particular, copper and copper‐derived catalysts have exhibited the ability to produce a number of organic molecules from CO 2 . Herein, we report a chloride (Cl)‐induced bi‐phasic cuprous oxide (Cu 2 O) and metallic copper (Cu) electrode (Cu 2 O Cl ) as an efficient catalyst for the formation of high‐carbon organic molecules by CO

Electrolyte pH is an important parameter in determining the equilibrium concentrations of the carbon dioxide–bicarbonate–carbonate system as well as in mapping out the thermodynamically stable phases of tin dioxide (SnO 2 ) in an aqueous electrochemical system. Thus, we explored an optimized region in the combined potential–pH ( E –pH) diagram of the two systems where there is a simultaneously high catalytic activity for carbon dioxide (CO 2 ) electrolysis and good phase stability for the SnO 2

Here, we first report an octahedral Co2+-rich Co oxide with inactive Sb5+ ion as an oxygen evolution reaction (OER) electrocatalyst for efficient H2 production by lowering the cell voltage in anion exchange membrane water splitting (AEMS). To enhance the OER activity of Co-based oxides, it is crucial to increase the amount of Co4+ at OER potential, known as the fast OER active site. Using in situ X-ray absorption spectroscopy, we observed most of the octahedral Co2+ in trirutile CoSb2O6 oxidized
