Redox flow batteries, which have been developed over the last 40 years, are used to store energy on medium large scale, particularly in applications such as load levelling, power quality control and facilitating renewable deployment. Various electrode materials cell chemistries proposed; some of successful systems demonstrated a large-scale range 10 kW–10 MW. Enhanced performance is attributable improvements electrodes, separator an increasing awareness design. This comprehensive review...

The two-electron water oxidation reaction (2e– WOR) is progressively gaining traction as a sustainable approach for in situ electrosynthesis of hydrogen peroxide (H2O2). State-of-the-art 2e– WOR electrocatalysts have shown great promise at low electrical currents yet exhibit diminished electrocatalytic capabilities larger current densities. Herein, by tailoring the boron doping level boron-doped diamond (BDD) microfilms, we fabricated an active, selective, and stable electrocatalyst WOR....

Electrochemical production of hydrogen peroxide (H2O2) has recently gained traction as a green alternative to the unsustainable anthraquinone auto-oxidation process and high-risk direct synthesis route. While two-electron oxygen reduction reaction (2e– ORR) toward H2O2 been covered extensively in literature, unorthodox water oxidation WOR) remains far less popular, due thermodynamic unfavorability pathway. Nonetheless, 2e– WOR constitutes coveted procedure it enables electro-generation...

Redox flow battery (RFB) is a promising technology to store large amounts of energies in liquid electrolytes attributable their unique architectures. In recent years, various new chemistries have been introduced both aqueous and non-aqueous as pathways lower-cost systems, eventually meeting the long-term cost target USD$ < 100 (kW h)−1 for board market penetration. Since there lack capital data available batteries under same criteria assumptions, fact-based techno-economic analysis evaluated...

Abstract Thin films of cobalt, prepared in ultra-high-vacuum at 4 K and examined situ by scanning electron diffraction, are shown to be amorphous with a radial distribution function similar that obtained theoretically serial deposition atoms the computer-simulated model developed Bennett. The effects removal lossy electrons (by velocity filtering), subtraction substrate background, multiple scattering on diffraction profile investigated discussed.

CO2 reduction processes continue to be developed for electrosynthesis, energy storage applications, and environmental remediation. A number of promising materials have shown high activity selectivity target products. However, the progress has been mainly at a small laboratory scale, technical challenges large scale not considered adequately. This review covers recent advancements in catalyst cell designs. The leading useful products are presented with their corresponding reactor latest...
