Rice lab advances water-splitting catalysts
Engineers develop stable devices that don’t require expensive iridium
26-Oct-2022
Creating ahydrogen economyis no small task, but Rice University engineers have discovered a method that could makeoxygen evolutioncatalysis in acids, one of the most challenging topics in water electrolysis forproducing clean hydrogen fuels, more economical and practical. The lab of chemical ...
Artificial Enzyme Splits Water
Progress has been made on the path to sunlight-driven production of hydrogen
05-Oct-2022
Chemists from Würzburg present a new enzyme-like molecular catalyst for water oxidation. Mankind is facing a central challenge: it must manage the transition to a sustainable and carbon dioxide-neutral energy economy. Hydrogen is considered a promising alternative to fossil fuels. It can be ...
Plastic upcycling: From waste to fuel for less
Problem plastics could be diverted from landfills and converted into fuel sources with new technology
25-Aug-2022
A plastics recycling innovation that does more with less, presented at the American Chemical Society fall meeting in Chicago, simultaneously increases conversion to useful products while using less of the precious metal ruthenium. “The key discovery we report is the very low metal load,” said ...
Rice process aims to strip ammonia from wastewater
Ruthenium and copper catalyze a more environmentally friendly way to produce essential chemical
04-May-2022
A dash ofrutheniumatoms on a mesh of copper nanowires could be one step toward a revolution in the global ammonia industry that also helps the environment. Collaborators at Rice University’sGeorge R. Brown School of Engineering,Arizona State Universityand Pacific Northwest National ...
Catalyst transforms plastic waste to valuable ingredients at low temperature
07-Jan-2021
For the first time, researchers have used a novel catalyst process to recycle a type of plastic found in everything from grocery bags and food packaging to toys and electronics into liquid fuels and wax. "Plastics are essential materials for our life because they bring safety and hygiene to our ...
Photocatalysts show promise in creating self-cleaning surfaces and disinfecting agents
New active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots
07-Sep-2020
A joint paper by Kazan Federal University, Boreskov Institute of Catalysis, and Russian Oil and Gas University was published in Chemistry - A European Journal. The team produced and studied new active photocatalysts based on natural aluminosilicate nanotubes with cadmium sulfide quantum dots ...
Chemicals for pharmaceuticals could be made cheaper and greener by new catalysts
04-Oct-2019
High value chemicals used to make pharmaceuticals could be made much cheaper and quicker thanks to a series of new catalysts made by scientists at the University of Warwick in collaboration with GoldenKeys High-Tech Co., Ltd. in China. The process of making high-value chemicals for uses such as ...
New process discovered: Mere sunlight can be used to eradicate pollutants in water
27-Nov-2018
Advances in environmental technology: You don’t need complex filters and laser systems to destroy persistent pollutants in water. Chemists at Martin Luther University Halle-Wittenberg (MLU) have developed a new process that works using mere sunlight. The process is so simple that it can even be ...
Phenyl addition made a poison useful for a chemical reaction in catalysis
20-Nov-2018
Scientists from Tokyo University of Agriculture and Technology (TUAT), Japan, have discovered that a catalyst poison, which deactivates homogeneous catalysts, can be "reborn" as an efficient ligand by introduction of a substituent, in chemical reactions. This finding is of service to expand the ...
A new nanocatalyst for obtaining hydrogen
19-Oct-2018
A chemist from RUDN was the first to use catalysts with ruthenium nanoparticles to obtain hydrogen under the influence of visible light and UV radiation. In the future, such catalysts may be used for large-scale production of hydrogen fuel under the influence of sunlight.Photochemical reactions ...
