A unique electrocatalytic oxidative dehydrogenation of aldehydes and its facile kinetics on a Cu-based porous electrode enables an ultra-low voltage bipolar H 2 production system with industrial-relevant current densities.
The electrochemical oxidation of furfural and down-pathway intermediate product species (furoic acid, 2(5H)-furanone, 5-hydroxy-2(5H)-furanone, maleic acid) is investigated on platinum electrodes via attenuated total reflectance surface-enhanced infrared absorption spectroscopy (ATR-SEIRAS) with modulation excitation (MES). Density functional theory (DFT) calculations are performed to further illuminate the elementary reaction mechanism surface orientations key intermediates. Evidence from...
Electrocatalytic Cu is key to the development of processes that can convert CO and CO2 hydrocarbons, nitrate ammonia. The hydrogen evolution reaction (HER) often competes with these processes. Few studies studied this on under alkaline conditions. Herein, we examined HER electrodes conditions in Na+- Cs+-containing electrolytes. We found 0.1 M solutions NaOH CsOH highest commercially available purity grades, trace impurities iron deposit electrode during electrolysis. As a result, rate...
Density functional theory (DFT) modeling has been useful to electrocatalyst research, yet simulating the complexities of electrode–electrolyte interface hinders progress in understanding reaction mechanisms and underlying kinetics. Though many approaches incorporating electrochemical double layer (EDL) features DFT calculations have developed, uncertainty interfacial solvent properties distribution ions leave impact EDL on electrocatalytic kinetics unclear. Elucidating sensitivity...
Partial oxidation of multifunctional oxygenates is interest for the production high-value chemicals, but understanding mechanism on Pt catalysts lacking. To probe effects oxygen in reaction furanics Pt(111), temperature-programmed desorption (TPD), high-resolution electron energy loss spectroscopy (HREELS), electrochemical catalytic experiments, and density functional theory (DFT) calculations were conducted. The presence Pt(111) surface significantly altered paths furan furfuryl alcohol...
Water electrolysis has been considered a green process for hydrogen production. Conventional is limited by the sluggish anodic oxygen evolution reaction (OER), leading to high energy input. In addition, temporal spatial coupling of production H 2 and O can cause issues associated with safety, economic feasibility, system flexibility. Herein, we reported our work on replacing OER an electrocatalytic oxidative dehydrogenation (EOD) biomass-derived furfural bipolar (from both cathode anode) at...

It is critical to fight against global warming and confine it a manageable level of +1.5°C by curbing CO 2 emissions, eventually achieving zero net emissions 2050. This target will involve significant efforts from all industry sectors require renewable energy storage conversion, most which are heavily rely on clean hydrogen production. Water electrolysis, producing oxygen water electricity, promising route the decarbonization transportation. The main source loss in electrolysis unfavorable...
