Eco-Friendly Battery Performance Enhanced Using Catalysts with Unusual Phase Nanostructures catalysts nanostructures nanocatalysts nanotechnology nano
The study presents a unique design of catalysts for a new class of meta-gas batteries that can benefit carbon-neutral goals.
Nevertheless, metal-CO2 batteries still experience slow reaction kinetics. This results in large over-potential , poor reversibility, low energy efficiency, and inadequate cycling stability. Related Stories“But we found preparing novel catalysts with unconventional phases to be a feasible and promising strategy to boost the energy efficiency and performance of metal-gas batteries, especially since traditional modification strategies for catalysts have encountered long-term technical hurdles,” Dr. Fan Zhanxi added.
Dr Fan Zhanxi, Study Lead and Assistant Professor, Department of Chemistry, City University of Hong Kong Outstanding Performance of Unconventional Phase Metal Nanomaterials The combination of theoretical calculations and experiments carried out by the researchers exposed that 4H/fcc Ir nanostructures formed through phase engineering are more promising for the reversible development of amorphous/low-crystalline discharge items, thereby minimizing the overpotential and boosting the cycling steadiness of electrochemical redox reactions.

Research finds that two out of five adults who use cigarettes smoke mentholMenthol use has increased over the past decade among U.S. adults who smoke cigarettes, according to a study released by Columbia University Mailman School of Public Health and The City University of New York. Menthol use is much more common among adult smokers who are younger, from racial/ethnic minoritized groups and with mental health problems. The results are published in the journal Nicotine and Tobacco Research.
