Activating bulk nickel foam for the electrochemical oxidization of ethanol by anchoring MnO₂@Au nanorods

Abstract

Direct ethanol fuel cells (DEFCs) using the biomass-derived fuel is a promising sustainable energy conversion system for enabling a carbon-neutral society. Such an imperative task is impeded by the stability-deficiency...

Activating biomass carbon with metallurgical slag by pyrolysis in molten salt for high-performance supercapacitors

“…The density-functional-theory (DFT) calculations were performed by using the Vienna Ab initio Simulation Package (VASP) with Projector Augmented Wave (PAW) method. 1,2 The Perdew–Burke–Ernzerhof (PBE) functional for the exchange–correlation term was used with the projector-augmented wave method, with the kinetic energy cutoff of the electron wavefunctions being set as 450 eV. The convergence of energy and forces were set to be 1 × 10 −4 eV and 0.05 eV Å −1 , respectively.…”

“…Both the nonrenewable feature and greenhouse gas emissions of the traditional fossil fuels are pressurizing the society to develop sustainable energy supplies worldwide. 1–4 However, the most promising sustainable energies such as solar, wind, and hydro energy are highly intermittent, which means that storing the generated electricity from these fluctuating energies is in great need for promising a steady energy supply. 5–7 …”

Size-Optimized Silver Nanowires with Graphene Oxide for High-Performance Transparent Electrodes

“…Transparent electrode is one of the critical components for the modern electronic manufacture industry, being found in various electronic products such as touch panels, solar cells, light-emitting diodes and sensors et al [1][2][3][4] However, the functionality explosion of electronic products in recent year sets higher requirements for the transparent electrode. For example, the flexible and elastic transparent electrodes are being developed, [5][6][7][8] making the traditional fragile indium tin oxide film (ITO) to be replaced in urgent need.…”

Extending Silver Nanowire Modified Electrodes to Industrial Zinc Electrolyte for Copper Ion Detection

“…15,16 Electrode modification has become an essential step to improve the sensing performance of solid-state electrodes. 17,18 Chemically modified electrodes based on metallic nanowires have been used to improve the performance of electrochemical sensors. 19 The AgNWs on the electrodes introduce a rough, highly conductive, high-surface area surface, which can highly improve the catalytic activity of the electrodes.…”
