Chemical recycling makes useful product from waste bioplastic

Chemical process can be used to break down real consumer plastics and produce green solvent

25-May-2020

A faster, more efficient way of recycling plant-based "bioplastics" has been developed by a team of scientists at the Universities of Birmingham and Bath. The team has shown how their chemical recycling method not only speeds up the process, it can also be converted into a new product - a ...

Noble Metal Aerogels Enabled by Freezing

Multi-Scale Structured Materials for Electrocataly­sis and Photoelectro­catalysis

14-May-2020

TU Dresden chemists developed a freeze-thaw method, capable of synthesising various noble metal aerogels (NMAs) with clean surfaces and multiscale structure. In virtue of their hierarchical structures and unique optical properties, outstanding performance for electro-oxidation of ethanol is ...

Superatoms as catalysts

Prof. Roland Fischer awarded Reinhard Koselleck Project funding from the DFG

05-May-2020

Precious metals like platinum are good catalysts – but they are expensive. While the chemical industry is trying to solve this cost issue by developing ever-smaller catalyst particles, a team from the Technical University of Munich (TUM) is taking an entirely new approach: the targeted ...

Visible light-photocatalytic water-splitting for hydrogenation of aryl chlorides

Sustainable H-donors instead of flammable hydrogen gas

29-Apr-2020

Activation of inert C-Cl bonds has attracted significant interest due to the inherent fundamental challenge. Conventional dechlorination generally use flammable hydrogen gas (H2), metal hydrides, or organic donors (amines, alcohols, and Hantzsch ester) as hydrogenation reagents. Despite high ...

New catalyst opens door to more efficient, environmentally friendly ethylene production

Discovery could drastically reduce ethylene production costs

28-Apr-2020

A research team led by North Carolina State University has engineered a new catalyst that can more efficiently convert ethane into ethylene, which is used in a variety of manufacturing processes. The discovery could be used in a conversion process to drastically reduce ethylene production costs ...

Titanium catalyst enables reactions with the help of green light

Cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far

23-Apr-2020

For the first time, chemists at the University of Bonn and Lehigh University in Bethlehem (USA) have developed a titanium catalyst that makes light usable for selective chemical reactions. It provides a cost-effective and non-toxic alternative to the ruthenium and iridium catalysts used so far, ...

Manipulating ligands

A new dimension for promoting electrocatalysis performance by noble metal aerogels

27-Mar-2020

Noble metal aerogels (NMAs) are an emerging class of porous materials embracing nano-sized highly-active noble metals and porous structures, displaying unprecedented performance in diverse electrocatalytic processes. However, various impurities, particularly organic ligands, are often involved in ...
