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 ...

Building-Kit Catalyst

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 ...

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 ...

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 ...

Anionic Nickel

Nickel-catalyzed cross-coupling of aromatic ethers proceeds via a nickelate anion

26-Oct-2021 - Metal catalysts are widely used in the production of drugs, dyes, adhesives, and plastics. Researchers have now discovered an intriguing property of nickel as a catalyst: it is able to catalyze the coupling of aromatic hydrocarbons in its anionic form, the nickelate ion. In this form, the two ...
