Intensive research in electrochemical CO2 reduction reaction has resulted the discovery of numerous high-performance catalysts selective to multi-carbon products, with most these still being purely transition metal based. Herein, we present high and stable products selectivity up 76.6% across a wide potential range 1 V on histidine-functionalised Cu. In-situ Raman density functional theory calculations revealed alternative pathways that involve direct interactions between adsorbed histidine...
The electroreduction of CO2 (CO2RR) using renewable electricity is an appealing route to synthesize methanol (CH3OH), a valuable C1 feedstock and fuel. Unfortunately, there are still no workhorse electrocatalysts with suitable activity selectivity for this reaction. Currently, formic acid (HCOOH), CO, methane the most common products. Since multielectron electrocatalytic reactions can be severely affected by adsorption-energy scaling relations, tandem process likely offers higher efficiency....
Abstract Cationic ammonium surfactants can be used together with a suitable catalyst to enhance the electroreduction of carbon dioxide (CO 2 RR). However, underlying reasons for improvements are not yet well understood. In this study, it is shown that didodecyldimethylammonium bromide (DDAB; [(C 12 H 25 ) N(CH 3 ]Br), when added catholyte, increase rate CO reduction on silver electrodes by 12‐fold at −0.9 V versus reversible hydrogen electrode. More importantly, electrochemical impedance...
A crucial task towards creating a sustainable chemical industry is the electrification of processes that produce value-added molecules. One such molecule 1,3-butadiene (1,3-BD), feedstock used for manufacturing synthetic rubber. 1,3-BD traditionally derived, as by-product, during energy-intensive steam cracking naphtha to ethylene. Here we introduce an alternative approach selectively from electroreduction acetylene (e-C2H2R). By using potassium iodide electrolyte, created Cuδ+–Cu0 sites on...
Conjugated polymers are promising materials for thermoelectrics as they offer good performances at near ambient temperatures. The current focus on polymer thermoelectric research mainly targets a higher power factor (PF; product of the conductivity and square Seebeck coefficient) through improving charge mobility. This is usually accomplished via structural modification in conjugated using different processing techniques doping. As result, structure-charge transport relationship generally...
