Carbon recycling instead of plastic trash

Iron electrocatalysis breaks down polystyrene and delivers green hydrogen

14-Nov-2024 - Plastics are inescapable in our daily lives. The vast amounts of plastic garbage heaped in landfills and in the environment, however, are as problematic as the plastics are useful. In the journal Angewandte Chemie, a German research team has now introduced a new method for recycling polystyrene ...

Metal-free organic framework for electrocatalytic production of ethylene from carbon dioxide

24-May-2024 - Use of the greenhouse gas CO2 as a chemical raw material would not only reduce emissions, but also the consumption of fossil feedstocks. A novel metal-free organic framework could make it possible to electrocatalytically produce ethylene, a primary chemical raw material, from CO2. As a team has ...

Primordial Photoredox Catalyst

Nitrogen-Doped Graphite Catalyzes Reactions to Give Early Biomolecules

13-Jul-2023 - The sun as a source of energy, and catalysts to accelerate chemical reactions, were of critical importance in the emergence of the first biochemical molecules on Earth. A research team has now shown that a solid deposited from ammonia and methane plasma is capable of using light energy for ...

The Evolution of a Catalyst

Using a genetic algorithm to uncover new catalyst molecules for organic synthesis

24-Mar-2023 - A team of researchers have used a computational method inspired by evolution to discover an organic catalyst with better performance than known catalysts. As the team reports in the journal Angewandte Chemie, a genetic algorithm suggested new, catalytically active molecular structures for a ...

Nanocrystals Store Light Energy and Drive Chemical Reactions

Low toxicity, high efficiency: ZnSe/ZnS quantum dots as photocatalysts

15-Nov-2022 - Chemistry is increasingly making use of the trick plants can do with photosynthesis: driving chemical reactions that run poorly or do not occur spontaneously at all with light energy. This requires suitable photocatalysts that capture light energy and make it available for the reaction. In the ...

Fuel from a Greenhouse Gas

Single gold atoms catalyze the selective methanization of carbon dioxide

15-Sep-2022 - One step toward carbon dioxide (CO2) neutrality and the mitigation of both the greenhouse effect and the energy crisis would be to convert CO2 into hydrocarbon-based fuels like methane using light. In the journal Angewandte Chemie, a Chinese research team has introduced a highly effective ...

Economical PEF Production

Efficient titanium-based catalyst used to produce PEF, the biobased alternative to PET

30-Aug-2022 - One possible replacement for drink containers made from PET is polyethylene furandicarboxylate (PEF), made from renewable resources. However, the production of the raw material for PEF from biomass is still rather inefficient. A new titanium-based photocatalyst could be about to change this, ...

Step toward a Circular Economy?

Catalytic deconstruction of PET with zirconium metal–organic framework

11-May-2022 - Polyethylene terephthalate (PET) is one of the most common plastics. Discarded PET most often ends up in landfills or in the environment because the rate of recycling remains low. In the journal Angewandte Chemie, a research team has now reported a zirconium-based metal–organic framework material ...

Methane from Carbon Dioxide

Efficient catalyst for the light-driven methanation of CO2

19-Nov-2021 - Recycling carbon dioxide (CO2), especially through conversion to methane (CH4), is compelling while anthropogenic CO2 emissions are still rising. A useful process for this transformation is photothermal methanation, in which CO2 and hydrogen are catalytically converted into CH4 and water upon ...

Liquid Fuels from Carbon Dioxide

Electrocatalyst converts CO2 into multicarbon products

18-Nov-2021 - A new electrocatalyst called a-CuTi@Cu converts carbon dioxide (CO2 ) into liquid fuels. As reported by a team of Chinese researchers in the journal Angewandte Chemie, active copper centered on an amorphous copper/titanium alloy produces ethanol, acetone, and n-butanol with high efficiency. Most ...
