Soaking up CO₂ emissions

See on - Technology Futures

CSIRO scientists have created a ‘solar sponge’ that captures and then releases carbon dioxide using the power of natural sunlight – as published in the scientific journal Angewandte Chemie.

The breakthrough presents a new way to recycle CO2 emissions using renewable energy. The ‘sponge’ which is made from a new smart material called a MOF (metal organic framework) adsorbs carbon dioxide, but when exposed to sunlight, instantaneously releases it.

Known as dynamic photo-switching, this capture-and-release method is extremely energy efficient and only requires UV light to trigger the release of CO2 after it has been captured from the mixture of exhaust gases.
