UCSC team develops high-performance nanostructured composite catalyst for water-splitting to produce hydrogen

By mmillikin A low-cost, nanostructured composite material developed by researchers at UC Santa Cruz has shown performance comparable to Pt/C as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.

Researchers led by Shaowei Chen, professor of chemistry and biochemistry at UC Santa Cruz, incorporated ruthenium ions into graphitic carbon nitride/reduced graphene oxide (rGO) hybrids to form Ru−C3N4/rGO composites. They found that the incorporation of Ru ions, at a loading of 1.93 at. %, leads to electron redistribution within the materials and significantly enhanced the
