¨ An innovative method to
improve catalysts used for water splitting has been developed by Scientists at
the Centre for Nano and Soft Matter Sciences (CeNS) in Bengaluru.
¨
Water splitting is a key process in generating
clean hydrogen.
¨
This development deals with challenge in the oxygen
evolution reaction (OER).
¨
Oxygen evolution reaction (OER) is slower and more
energy-intensive than the hydrogen evolution reaction (HER).
¨
The focus of scientists was on improving
coordination polymers.
¨
Coordination polymers are a class of materials
formed by metal ions and organic molecules that are used in electrolysis.
¨
They often show limited activity because solvent
molecules block many of their active sites available for reactions.
¨
Scientists at CeNS used argon plasma to activate
the COPs by producing coordinatively unsaturated metal sites.
¨
Analyses confirmed that Ni- and Co-based polymers
were more active without altering their bulk framework.
¨
The study was published in '"ACS Applied Nano
Materials".
¨ This method has the
potential to speed up the development of affordable hydrogen energy solutions.
