IISER Pune team synthesises photo-catalyst to degrade organic pollutants
Why is it in news?
- Researchers at the Indian Institute of Science Education and Research (IISER) Pune have successfully converted the highly unstable perovskite into a highly stable photo-catalyst capable of decomposing toxic organic pollutants commonly present in water
More in news
- The catalyst that becomes active when exposed to sunlight was synthesised by encapsulating nanocrystals of organic-inorganic perovskite inside a metal-organic framework (MOF).
- The team from the Department of Chemistry at IISER Pune utilised the hydrophobic nature of the MOF material to render greater chemical stability to perovskitenanocrystals that form inside the MOF cavities.
- The perovskite-MOF composites displayed “outstanding” stability when immersed inside water and alcoholic solvents for as long as 90 days.
- What are pervoksites?
(1) A perovskite is any material with the same type of crystal structure as calcium titanium oxide (CaTiO3), known as the perovskite structure, with the oxygen in the edge centers.
(2) Perovskites take their name from the mineral, which was first discovered in the Ural mountains of Russia by
(3) Gustav Rose in 1839 and is named after Russian mineralogist L. A. Perovski (1792–1856)
