Achieving high electrochemical conversion of carbon dioxide (CO2) into valuable fuels and chemicals is one the most promising directions to address environmental energy challenges. Although several single-crystal based studies simulation results have reported that rich in steps on Cu (100) surfaces are favorable convert toward C2 alcohol products, still stuck low-index facets or surface defect-derived low density step-sites. In present work, we report production ethanol by synthesizing a...
Although the electroconversion of carbon dioxide (CO2 ) into ethanol is considered to be one most promising ways using CO2 , selectivity less than 50% because difficulties in designing an optimal catalyst that arise from complicated pathways for electroreduction ethanol. Several approaches including fabrication oxide-derived structures, atomic surface control, and Cu+ /Cu interfaces have been primarily used produce . Here, a combined structure with high-facets as electrocatalysts constructed...
Abstract Uniform lithium deposition is essential to hinder dendritic growth. Achieving this demands even seed material distribution across the electrode, posing challenges in correlating electrode's surface structure with uniformity of distribution. In study, effect periodic and facet orientation on investigated using a model system consisting wrinkled copper (Cu)/graphene [100] orientation. A new methodology developed for uniformly distributed silver (Ag) nanoparticles over large area by...
We demonstrate the relationship between work function of current collector and electrolyte decomposition. This can give an insight into how to design electronic structure for advanced anode-free LMBs.
Spatial control of lithium deposition is the most important issue in lithium‐metal batteries because considerable dendrite suppression via uniform distribution Li + flux. Although seed materials are crucial for behavior deposition, in‐depth studies on their physical and chemical have not been conducted. Here, we describe a new design structure comprising wrinkled Cu/graphene substrate surrounded by copper(I) oxide (Cu 2 O) graphene grain boundary over large area, which fabricated oxidation...
