Novel Microporous Nanoalloy Graphene Composite for Electrocatalytic Water Splitting

The functional materials group at the Center for Materials Science (CMS) at Zewail City of Science and Technology, led by Prof. Mohamed Alkordi, director of the Materials Science program and co-director of CMS has synthesized a novel composite of Ni/Fe nanoalloy atop graphene nanosheets (NiFe@G).

The new composite was synthesized from non-precious metal salts and organic ligands to produce the hybrid ultramicroporous SIFSIX-3-NiFe homogeneously deposited atop graphene nanosheets followed by an annealing process to attain the true active catalyst.

The developed NiFe@G displayed good mechanical strength, thermal and electrical conductivity with exceptional performance towards electrocatalytic OER.

The reported methodology opens more doors for designing novel multifunctional heterogeneous electrocatalysts.
