A team of scientists led by researchers from the Indian Institute of Technology (IIT)
Gandhinagar, Gujarat, has developed a nano-composite that selectively converts carbon monoxide in the environment into less toxic carbon dioxide.
Carbon monoxide (CO)
It is the main air pollutant that poses a serious threat to health.
This new composite is an alloy made of graphene and platinum and palladium in the form of nanoparticles.
In the project, graphene was used as a substrate and then \"decorated\" alloy nanoparticles made of platinum and palladium \".
This new catalytic structure is then used for the selective oxidation of CO to co2.
The use of metal particles with a certain orientation to absorb or interact with CO at a lower energy contributes to conversion.
\"Once integrated, what controls the catalytic efficiency of the mixed material is the size and shape of the nanoparticles.
The efficiency of any catalyst depends on the availability of the active site and the surface area of the nanoparticles.
Therefore, it is essential to design the morphology of alloy nanoparticles and their combination with graphene for catalytic performance . \"
Secretary-General: Tiwary, member of the Gandhi Nagar research group for personal income tax.
\"Although platinum and palladium are active catalysts themselves, it is really amazing to get them alloy with graphene.
Due to the synergy between the three, the mixture showed high adsorption and reaction, \"Professor
Sudhanshu Sharma, also said from Gandhi Nagar of IIT.
The catalytic behavior of nano-composite materials for CO oxidation was studied using different morphology.
The conversion rate varies with CO flow and temperature, showing a complete conversion rate at 75 ° to 125 °.
\"These are the initial results that are exciting.
We are trying to build a 3D porous building using this hybrid material in practical applications and at room temperature, \"Dr. Tiwary said.
The researchers say this new material has potential uses in the chemical industry and environmental cleaning.
Experts, however, expressed caution.
\"While the concepts used are new and important because CO is a major environmental issue, it may take a while for this science to translate into technology because of experimental devices-
Up looks complicated and may not be commercially feasible . \"
Ramavatar Meena, a scientist at the Central Institute of salt and marine chemistry in Bhavnagar, Gujarat, has nothing to do with this study.
The study was conducted in collaboration with scientists from IIT Kanpur and the University of Campinas in Brazil.
The team includes S. Sreehala, R. S.
Kumar Mishra, Sudhanshu Sharma and C. S. Tiwary (
Gandhi Nagar for all personal income tax); M.
Manolata Devi, N.
Dolai of Krishanu Biswas (From IIT Kanpur); and Y. M.
Jerks and DouglasGalvao (
University of Campinas).
The results were published in the journal Nano scale of the Royal Society of Chemistry. —
