Study of a Novel Electrochemical Method for Copper Recovery from Waste Printed Circuit Boards

Chemical Engineering Transactions, 2017
This study was carried out to recover copper from printed circuit boards of waste computers through an electrochemical process. To simplify the overall recovery process, large pieces of printed circuit boards were used instead of pulverized samples.

Biomass Electrorefining: Electrical‐to‐Chemical Energy Relay Systems for Hydrogen‐Chemical Coproduction via Multi‐Reaction Electrocatalytic Cascades

Carbon Neutralization, Volume 5, Issue 1, January 2026.
This graphical abstract illustrates an integrated electrocatalytic refining system designed for sustainable chemical and fuel production. At its core, the Biomass Oxidation Reaction (BOR) replaces conventional water oxidation at the anode. It is coupled with various cathodic reactions, such as the Hydrogen Evolution Reaction (HER), CO2 Reduction (CO2RR)

Closing the Loop From Waste to Resource: A Comprehensive Review on Recycling Current Collectors in Lithium‐Ion Batteries

cMat, Volume 2, Issue 4, December 2025.
ABSTRACT Aluminium and copper foils constitute essential current collectors in lithium‐ion batteries (LIBs), critically influencing both battery performance and manufacturing costs. As LIB adoption grows exponentially, the sustainability and cost‐effectiveness of these current collectors have emerged as pivotal factors to establish circular economies ...

Investigations on Anode Quality in Copper Electrorefining

BHM Berg- und Hüttenmännische Monatshefte, 2008
Copper anodes have to have a certain quality in order to meet the requirements of subsequent electrorefining. The anode casting process is decisive for anode quality, which determines anodic dissolution behaviour during electrorefining. In order to determine the influences of the casting process and cooling conditions on chemical and physical anode ...

Electroplating of Wear‐ and Corrosion‐Resistant CrCoNi Medium‐Entropy Alloys beyond Hard Chromium Coatings

Advanced Functional Materials, Volume 35, Issue 22, May 29, 2025.
The electroplating of a CrCoNi medium‐entropy alloy is achieved using a mixture of an ionic liquid and an aqueous solution containing metal salts. The CrCoNi medium‐entropy alloy thin film exhibits high wear and corrosion resistance superior to conventional hard chromium coatings. Abstract High‐entropy alloys (HEAs) and medium‐entropy alloys (MEAs) are
