Copper-based materials are been consistently studied in the field of electrochemical cells, due to its superior electrocatalytic properties, low toxicity, and cost effectiveness. Its unique capabilities to enhance mass transport and sensing performance with high effective surface area have spurred advances in synthesizing various copper metal nanostructures for various uses. In this project, various copper-based nanostructures are developed in search for their application in photoelectrochemical (PEC) water splitting and glucose sensing reaction. Synthesis is conducted by disproportionation of copper and addition of gold to enhance copper nanostructures’ catalytic properties. Results showed that copper-gold bimetallic metals perform better than pristine copper and its oxides, for both photoelectrochemical cell and glucose sensing applications.
