Electrochemical sensing of tyrosine and removal of toxic dye using self-assembled three-dimensional CuBi2O4/rGO microsphere composite

In this work, a novel low-cost electrochemical sensor involving copper bismuthate (CuBi2O4) microspheres embedded in reduced graphene oxide (rGO) is described for electrochemical determination of L-Tyrosine (L-Tyr) and photocatalytic degradation of methylene blue (MB) in Parkinson's disease treatment and industrial waste treatment, respectively. The rGO improves the electrocatalytic behaviours of CuBi2O4 and enhances the sensing performance of...
