Scientists have looked into using gold and gold-platinum nanoparticle electrocatalysts

Scientists at the University of New York have
looked into using gold and gold-platinum nanoparticle electrocatalysts for
fuel cell reaction at the cathode.

The research was conducted in response to the growing demand for high conversion
technology, with scientists and companies looking to improve power sources
and make modern-day vehicles more environmentally friendly.

Electrocatalytic oxygen reduction reaction (ORR) activity was characterised
using voltammetric and rotating disk electrode techniques, according to the
team from the university’s department of chemistry.

In addition, current catalysts were also compared under the same measurement
conditions, according to Fuel Cell Today.

Catalysts were prepared using a two-phase protocol and were thermally activated
using calcination temperatures

The scientists claimed that results showed that gold and gold-platinum nanoparticle
catalysts are potentially viable candidates for fuel cell catalysts under
a number of conditions.

However the electrocatalytic properties are significantly changed depending
on the gold-platinum composition.

Experts claim the research provides important information on the electrocatalytic
activity of catalysts and will also help in the design of highly active fuel
cell catalysts.
