Activating palladium catalysis by light: teaching an old transition metal new tricks
Chemists develop method to produce π-allylpalladium complexes by radical chemistry
26-Mar-2020
In the production of compounds, chemists have the fundamental goal of finding strategies that are most selective and avoid waste products. Breakthroughs in this area serve, among other things, to drive industrial innovation and drug development. In this context, allylic substitution reactions ...
Closing the carbon cycle to stop climate change
Defects in nanosilica can save planet earth from global warming
20-Mar-2020
An excessive amount of carbon dioxide is the main cause of climate change. One of the best approaches is to capture and convert carbon dioxide (CO2) into fuel such as methane. On the other hand, a sustainable way to solve the energy problem is to generate alternative energy source, however, ...
Novel approach to enhance performance of graphitic carbon nitride
19-Mar-2020
In a report published in NANO, scientists from the Jiangxi University of Science and Technology, Guangdong University of Petrochemical technology, Gannan Medical University and Nanchang Hangkong University in China underline the importance of defect engineering to promote catalytic performance by ...
New catalyst provides boost to next-generation EV batteries
17-Mar-2020
Metal-Air Batteries (MABs), which use oxygen from ambient air as recourses to store and convert energy, have received considerable attention for their potential use in electric vehicles (EVs) owing to their large storage capacity, lightweight, and affordability. A research team, affiliated with ...
3D Hierarchically Porous Nanostructured Catalyst Helps Efficiently Reduce CO2
17-Mar-2020
KAIST researchers developed a three-dimensional (3D) hierarchically porous nanostructured catalyst with carbon dioxide (CO2) to carbon monoxide (CO) conversion rate up to 3.96 times higher than that of conventional nanoporous gold catalysts. This new catalyst helps overcome the existing ...
Novel Technique to Produce Cheaper and More Efficient Chlorine
12-Mar-2020
Chlorine (Cl₂) is one of the most widely used industrial chemicals in the world today, with75 million tons produced annually.A team of researchers, affiliated with UNIST has recentlyfound a way to make the manufacture of chlorine more efficient andaffordable. This is expected to be of great ...
Research uncovers a new way of making chiral catalysts
11-Mar-2020
Scientists at the University of Southampton have discovered a new way to create one hand of a chiral molecule by using a mechanical bond as a catalyst. Chiral molecules are two molecules that are mirror images of each other but not identical - much like the left and right human hands. When such ...
Water splitting observed on the nanometer scale
New method provides fundamental insights into electrocatalytic water splitting under operating conditions
06-Mar-2020
Whether as a fuel or in energy storage: hydrogen is being traded as the energy carrier of the future. To date, existing methodologies have not been able to elucidate how exactly the electrochemical process of water splitting into hydrogen and oxygen takes place at the molecular scale on a ...
Shaping the rings of molecules
Boon for the making of pharmaceuticals and electronics
25-Feb-2020
Macrocycles are molecules made of large rings of atoms. Despite being relatively big and flexible, the molecules don't always stay "floppy" -- they can actually lock themselves into specific shapes and geometries. In manufacturing, controlling the three-dimensional shapes of macrocycles is ...
Effective way to obtain fuel for hydrogen engines
24-Feb-2020
One of the most promising alternative energy sources is hydrogen, which can be extracted from water and air. A catalyst is needed for a chemical process that releases hydrogen from an H2O molecule. It can be made, for example, from platinum, or from molybdenum. But these are quite expensive ...
