Researchers provide new method to boost clean energy research

Electrochemical energy systems—processes by which electrical energy is converted to chemical energy—are at the heart of establishing more efficient generation and storage of intermittent energy from renewable sources ...

Metallic nanocatalysts imitate the structure of enzymes

An international team of researchers has transferred certain structural characteristics of natural enzymes, which ensure particularly high catalytic activity, to metallic nanoparticles. The desired chemical reaction thus ...

Tuning the electrocatalytic performance of bifunctional catalysts

In the search for highly active and inexpensive electrocatalysts, two reactions pose a particular challenge: the oxygen reduction reaction (ORR) and the oxygen evolution reaction (OER). Both are important for the development ...

New electrocatalyst developed for oxygen reduction reaction

Recent research published in a paper in NANO by a team of researchers from Beihang University have fabricated a new type of VNQD-NG as nonprecious metal-based electrocatalyst for oxygen reduction reaction (ORR). The unique ...

Study reveals exactly how low-cost fuel cell catalysts work

In order to reduce the cost of next-generation polymer electrolyte fuel cells for vehicles, researchers have been developing alternatives to the prohibitively expensive platinum and platinum-group metal (PGM) catalysts currently ...
