New material for efficient separation of Deuterium at elevated Temperatures

21-Mar-2025 - A novel porous material capable of separating deuterium (D2) from hydrogen (H2) at a temperature of 120 K has been introduced. Notably, this temperature exceeds the liquefaction point of natural gas, thus facilitating large-scale industrial applications. This advancement presents an attractive ...

A new catalyst can turn methane into something useful

MIT chemical engineers have devised a way to capture methane, a potent greenhouse gas, and convert it into polymers

09-Dec-2024 - Although it is less abundant than carbon dioxide, methane gas contributes disproportionately to global warming because it traps more heat in the atmosphere than carbon dioxide, due to its molecular structure. MIT chemical engineers have now designed a new catalyst that can convert methane into ...

How catalysts remove dangerous nitrogen oxides

”If we know exactly where the reaction takes place, the production of catalysts can be controlled accordingly”

11-Oct-2024 - Catalysts belonging to the zeolite family help to remove toxic nitrogen oxides from industrial emissions. Researchers at the Paul Scherrer Institute PSI have now discovered that their complex nano porous structure is crucial. Specifically, individual iron atoms sitting in certain neighbouring ...

Synergistic roles of platinum nanoparticles and sodium ions within beta zeolites in n-alkylation of amines with aromatic alcohols

N-alkylamines synthesis through N-alkylation of amines with alcohols catalyzed by Beta zeolites encapsulated Pt nanoparticles

27-Oct-2023 - Organic N-alkyl amines are important chemical products and intermediate with wide applications in the fields of daily chemicals, pesticides, pharmaceuticals, surfactants, and life sciences.

A new way to decontaminate water and gas with a new 3D extra-large pore zeolite

An extra-large pore silica zeolite from a silicate chain developed

24-Jan-2023 - An international team of researchers with the participation of the Spanish National Research Council (CSIC) has created the most porous stable zeolite known to date, a new pure silica zeolite called ZEO-3. This zeolite was formed by an unprecedented topotactic condensation of a 1D silicate chain ...

New method for the technological use of 2D nanomaterials

02-Jun-2022 - Nanosheets are finely structured two-dimensional materials and have great potential for innovation. They are fixed on top of each other in layered crystals, and must first be separated from each other so that they can be used, for example, to filter gas mixtures or for efficient gas barriers. A ...

Recycling CO2 to fuel a carbon-neutral future

The conversion of captured CO2 into fuels and other valuable hydrocarbons could enable a sustainable nonfossil-fuel-based economy

16-Nov-2021 - Multifunctional catalysts that transform captured carbon dioxide (CO2) into fuels and other valuable petrochemicals have been developed at KAUST and are set to enable a sustainable greener economy independent of conventional fossil fuels. The catalysts could help reverse the ever-increasing ...

Thermal storage for the energy transition

The energy is not stored in the form of increased heat but in the form of a chemical state

05-Oct-2021 - In Germany, 55 percent of final energy consumption goes towards heating and cooling. However, a lot of heat dissipates unused because it is not generated as and when required. Thermal storage using zeolite material allows heat to be stored for long periods of time without losing any. Fraunhofer ...
