Fish gills used to develop low-cost electrocatalyst for energy conversion devices

New Delhi (NVI): Scientists at the Institute of Nano Science and Technology (INST), Mohali, have recently come up with an efficient, low-cost electro-catalyst from fish gills that can help develop environmentally friendly energy conversion devices.

INST, Mohali is an autonomous institute under the Department of Science and Technology.

An electrocatalyst participates in electrochemical reactions. The role of catalyst materials is to modify and increase the rate of chemical reactions without being consumed in the process. Electrocatalysts are a specific form of catalysts that function at electrode surfaces or may be the electrode surface itself.

The bio-inspired carbon nanostructure used by scientists at INST can help overcome the bottleneck in the realization of several renewable energy conversion and storage technologies such as fuel cell, biofuel cell, and metal−air battery, Ministry of Science and Technology said.

The present strategy enriches a route to synthesize low-cost, highly efficient bioinspired electrocatalyst that is better than commercial Platinum on carbon (Pt/C) catalyst and could be utilized as next-generation nonprecious carbon-based electrocatalyst for energy conversion and storage applications, it said.

The results have been recently published in the journal Inorganic Chemistry published by the American Chemical Society, 2020.

The researchers have suggested that the careful selection of transition metals and heteroatoms together with engineering the synthesis protocol can pave a new way for exploring highly active low-cost electrocatalyst for efficient and environmentally friendly energy conversion devices, the Ministry said.
