Going Beyond Silver in Ethylene Epoxidation with First‐Principles Catalyst Screening
Angewandte Chemie, Volume 135, Issue 31, August 1, 2023., 2023 Using computational screening of the periodic table for ethylene epoxidation catalysts, Ag/CuPb, Ag/CuCd, and Ag/CuTl were identified as superior catalysts. The inclusion of surface oxidation, side reactions and epoxide decomposition is shown to be paramount to avoid erroneous predictions.

Statistical analysis of the distribution of impurities during copper electrorefining
Izvestiya Vuzov. Tsvetnaya Metallurgiya (Universities' Proceedings Non-Ferrous Metallurgy), 2021 Electrolytic copper refining makes it possible to obtain high purity metal, so the analysis of the main ways of impurity transition into electrolysis products is an actual problem. If it is solved, the process can be controlled when changing the composition of raw materials and, as a result, the content of impurities in the anodes.
