Chemists used crab shells to improve palladium catalysts
A new type of palladium catalysts based on chitin can be reused over 10 times
17-Dec-2020
Chemists from RUDN University synthesized soluble biopolymers based on chitin from crab shells. Together with palladium, they form effective catalysts for organic reactions, and their nanoparticles can be re-used over ten times. Palladium-based catalysts are used to speed up cross-coupling ...
Disproving the universal nature of the mercury test
Mercury test of catalysts that has been considered universal for 100 years seems to be ambiguous
26-Oct-2018
The mercury test of catalysts that has been used and considered universal for 100 years, turned out to be ambiguous. This conclusion was made by a group of scientists including a RUDN chemist. The group confirmed that the test required additional control experiments to verify its results. 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 ...
Nanoreactors to synthesize organic substances under visible light
A new type of photocatalysts -- nanostructures from titanium dioxide
11-Oct-2018
A RUDN chemist developed a new type of photocatalysts - nanostructures from titanium dioxide. Hollow nanocubes with ultra-thin walls act like nanoreactors and provide for 28 fold more effective organic reactions at room temperature under the influence of visible light. Traditional methods of ...
Diels-Alder reaction changes direction completely
29-Jun-2018
The Diels-Alder reaction is widely used in organic synthesis. Chemists appreciate its simplicity, reliability, and the ability to influence its course and change the conditions of the process. Several products of these transformations are used to create graphene-like materials, product vitamins, ...
