Newly discovered enzyme breaks down PET plastic in record time

Research finding could help make biological recycling more commercially viable

18-May-2022

Plastic bottles, punnets, wrap – such lightweight packaging made of PET plastic becomes a problem if it is not recycled. Scientists at Leipzig University have now discovered a highly efficient enzyme that degrades PET in record time. The enzyme PHL7, which the researchers found in a compost heap ...

Converting excess atmospheric CO₂ into energy-rich chemicals

Lights, catalyst, reaction! Converting CO₂ to formic acid using an alumina-supported, iron-based compound

17-May-2022

Photoreduction of CO2 into transportable fuel like formic acid (HCOOH) is a great way of dealing with CO2’s rising levels in the atmosphere. To aid in this mission, a research team from Tokyo Tech chose an easily available iron-based mineral and loaded it onto an alumina support to develop a ...

Energy researchers invent chameleon metal that acts like many others

Research could improve efficiency for storing renewable energy, making carbon-free fuels, and manufacturing sustainable materials

12-May-2022

A team of energy researchers led by the University of Minnesota Twin Cities have invented a groundbreaking device that electronically converts one metal into behaving like another to use as a catalyst for speeding chemical reactions. The fabricated device, called a “catalytic condenser,” is the ...

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 ...

Scientists solve mystery about catalysis for green production of methanol from carbon dioxide

Live view into methanol synthesis

10-May-2022

An international research team led by researchers of Stockholm University has for the first time been able to study the surface of a copper-zinc catalyst when carbon dioxide is reduced to methanol. The results – obtained at DESY´s brilliant light source PETRAIII – are published in the scientific ...

New organocatalysts can compete with enzymes

Particular interest to the chemical and pharmaceutical industries

09-May-2022

Organocatalysis not only provides an imaginable alternative to classical catalytic processes, but is even more efficient in many cases - and thus of particular interest to the chemical and pharmaceutical industries. More than 20 years ago, Ben List and his Scottish colleague David MacMillan found ...
