Catalysts: Poisoned and very much alive at the same time

A surprising discovery: A catalyst seems to contradict usual laws and can exhibit completely different activity states at the same time

17-Nov-2021

Sometimes chemical reactions in the lab work the way you imagine them to, and sometimes they don't. Neither is unusual. What is highly unusual, however, is what a research team at TU Wien has now observed when studying hydrogen oxidation on a rhodium catalyst: The surface of a rhodium foil can be ...

Less is more: 'Reduction' allows for cleaner and more efficient catalytic reactions

17-Aug-2021

In an ongoing effort to accelerate catalytic reactions, oxidation of metal complexes using light has emerged as a standard method to synthesize aromatic compounds. Now, researchers at Tokyo Institute of Technology have demonstrated a high-yield synthesis pathway through reduction of rhodium ...

Using ultra-low temperatures to understand high-temperature superconductivity

A surprising discovery could help solve the riddle of high-temperature superconductivity

23-Jul-2021

At low temperatures, certain materials lose their electrical resistance and conduct electricity without any loss - this phenomenon of superconductivity has been known since 1911, but it is still not fully understood. And that is a pity, because finding a material that would still have ...

Nanoparticles: The Complex Rhythm of Chemistry

Nanoparticles are often used as catalysts. The chemical reactions on their surface are more complex than previously thought

26-May-2021

Most of commercial chemicals are produced using catalysts. Usually, these catalysts consist of tiny metal nanoparticles that are placed on an oxidic support. Similar to a cut diamond, whose surface consists of different facets oriented in different directions, a catalytic nanoparticle also ...

Methane to syngas catalyst: two for the price of one

10-Sep-2018

Hokkaido University researchers have created an improved catalyst for the conversion of methane gas into syngas, a precursor for liquid fuels and fundamental chemicals. Syngas, also known as synthesis gas, is a mixture made primarily of carbon monoxide and hydrogen and is used to manufacture ...

Hybrid catalyst with high enantiomer selectivity

10-Aug-2018

A group of Japanese researchers has developed a technology to create a hybrid catalyst from simple-structured, commercially available rhodium and organic catalysts, which reduces chemical waste and produces molecules with high selectivity of an enantiomer, a pair of molecular structures that are ...

New world record for direct solar water-splitting efficiency

06-Jul-2018

Hydrogen will play a central role as a storage medium in sustainable energy systems. An international team of researchers has now succeeded in raising the efficiency of producing hydrogen from direct solar water-splitting to a record 19 per cent. They did so by combining a tandem solar cell of ...

Modern alchemists are making chemistry greener

18-Jun-2018

Ancient alchemists tried to turn lead and other common metals into gold and platinum. Modern chemists in Paul Chirik's lab at Princeton are transforming reactions that have depended on environmentally unfriendly precious metals, finding cheaper and greener alternatives to replace platinum, ...

Edges and corners increase efficiency of catalytic converters

X-rays reveal oxide islands on noble metal nanoparticles

28-Mar-2018

Catalytic converters for cleaning exhaust emissions are more efficient when they use nanoparticles with many edges. This is one of the findings of a study carried out at DESY’s X-ray source PETRA III. A team of scientists from the DESY NanoLab watched live as noxious carbon monoxide (CO) was ...

Breakthrough process for directly converting methane to methanol

04-Dec-2017

The direct oxidation of methane--found in natural gas--into methanol at low temperatures has long been a holy grail. Now, researchers at Tufts have found a breakthrough way to accomplish the feat using a heterogeneous catalyst and cheap molecular oxygen, according to a paper published by a team ...
