Role of cadmium gallate nanoparticles on the cathode of microbial fuel cells for enhanced bioelectricity production

Bringing microbial fuel cells (MFCs) to market requires the use of non-precious metal catalysts. Therefore, we replaced the platinum (Pt) cathode with more cost-effective cadmium gallate (CdGa2O4) nanoparticles in the present research. The synthesis and characterization of cadmium gallate (CdGa2O4),...
