Gold Alloyed With Nickel Studied For Hydrogen Production
August 23, 2023 | Leave a Comment
Chiba University researchers show the hydrogen evolution reaction activity of a GoldNickel/Gold electrocatalyst increases due to surface defects formed via Nickel dealloying. Gold (Au)-based electrocatalysts used for hydrogen production via water electrolysis exhibit high chemical stability but low hydrogen evolution reaction (HER) activity. Alloying them with nickel (Ni) can improve their HER activity. Now, a […]

A research team led by Kazuhiko Maeda at the Tokyo Institute of Technology has developed a new photocatalyst. They have developed a hybrid material constructed from a metal oxide nanosheet and a light-absorbing molecule for splitting water molecules (H2O) to obtain dihydrogen (H2) under sunlight. Since H2 can be used as carbon-free fuel, this study […]

Rice University researchers have integrated high-efficiency perovskite solar cells and electrode catalysts into an efficient, low-cost device that splits water to produce hydrogen fuel. The platform developed by the Brown School of Engineering lab of Rice materials scientist Jun Lou integrates catalytic electrodes and perovskite solar cells that, when triggered by sunlight, produce electricity. The […]

On the Hunt For the Green Bullet Catalyst
November 21, 2019 | 1 Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Trinity College Dublin researchers have made a major discovery that will make it immeasurably easier for people (or super-computers) to search for an elusive ‘green bullet’ catalyst that could ultimately provide entirely renewable energy. The press release asserts this is a giant stride towards solving a riddle that would provide the world with entirely […]

Progress Made In Using Iron Rust to Split Water
November 13, 2019 | 1 Comment
Yale University researchers say rust has long been seen as a potentially attractive material for solar water splitting, a key process that plants employ in photosynthesis. The search for sustainable approaches to generating new fuels has brought scientists back to one of the most abundant materials on Earth – reddish iron oxide in the form […]
