CSMCRI developed photocatalyst that can completely degrade three industrial dyes in the presence of sunlight.

Researchers from the Central Salt & Marine Chemicals Research Institute (CSMCRI), Bhavanagar, Gujarat have developed photo catalyst that can completely degrade three industrial dyes in the presence of sunlight. 
•    This photo catalyst is able to completely degrade three industrial dyes — methyl orange, methylene blue and reactive black-5. 
•    The photo catalyst was developed using titanium dioxide doped with red seaweed polymer carrageen an (a substance extracted from purple and red seaweeds). 
•    So the researchers from CSMCRI doped titanium dioxide nano particles with sulphur and carbon by treating it with carrageen an.
•    The nano composite was found to behave as an excellent photo catalyst that degraded the industrial dyes quickly in a single-step process. 
•    The nano composite photo catalyst is thermally stable. It can be reused up to 6 times with the degradation efficiency remaining at over 97%.
