The influence of non-ionic surfactants on electrosynthesis in extended channel, narrow gap electrolysis cells [PDF]

, 2019
It is demonstrated that the addition of a non-ionic surfactant (Triton X-100 or Brij L23) to the electrolyte medium leads to a significant improvement to the current efficiency for the methoxylation of N-formylpyrrolidine in a flow electrolysis cell with

Assessing the Oxidative Stability of Anion Exchange Membranes in Oxygen Saturated Aqueous Alkaline Solutions

Frontiers in Energy Research, 2022
While anion exchange membrane water electrolyzers show promise as a source of green hydrogen using low-temperatures and non-platinum group metal catalysts, many concerns must be addressed. A primary challenge for the development of high-performance anion

Methods for Enhancing Electrolysis for Hydrogen Production: The Benefits of Applying Magnetic Fields

Energies
The electrolysis of water is one of the most promising ways of producing green hydrogen. This produces hydrogen using electricity and does not generate additional carbon dioxide like the more conventional reforming of fossil fuels.

Development of Recycling Process for Copper-Gallium Target

Journal of MMIJ, 2018
Gallium is used as a raw material for a CIGS solar cell. In the manufacturing process of CIGS solar cells, only 30% of the target material is used, and the rest is not used and becomes a spent target scrap.
