New Nanocomposite can help in Cleaning Air

Carbon monoxide is a major air pollutant posing threat to human health. A team of scientists led by the researcher at the Indian Institute of Technology (IIT) Gandhinagar has developed a nanocomposite material that can selectively convert environmental carbon monoxide into less toxic carbon dioxide.

About the new material:

The new composite material is made of graphene and an alloy of platinum and palladium in the form of nanoparticles. Graphene was used as a substrate and then “decorated” with alloy nanoparticles made of platinum and palladium. The material was then used for selective oxidation of CO into CO2.

The catalytic behavior of the nanocomposite was studied using different morphologies for the oxidation of CO. The conversion rate varied along with the flow rate of CO as well as temperature, showing full conversion at temperatures ranging from 75° to 125°.

The new material could find potential use in chemical industries as well as environmental cleaning.

Graphene has been touted in the global electronics industry as a “miracle material” given its strength, electrical conductivity, and elasticity, and has been seen as an alternative to lithium-ion batteries since its discovery in 2004. It is a form of carbon that can be used to develop smaller, slimmer batteries but with higher capacity.

Graphene is a carbon material that is one atom thick. Its thin composition and high conductivity mean it is used in applications ranging from miniaturized electronics to biomedical devices. These properties also enable thinner wire connections; providing extensive benefits for computers, solar panels, batteries, sensors and other devices.

The potential applications of graphene include water filtration and purification, renewable energy, sensors, personalized healthcare, and medicine, to name a few.

Graphene has excellent electronic, mechanical, thermal and optical properties as well. Its uses range from improving battery performance in energy devices to cheaper solar panels.
