Carbon nanodots (CDots), a new class of nanosturctured carbons, display the strong catalytic behaviour. Combined with their other some advantages such as chemical stability, aqueous dispersibility, biocompatibility, intrinsic low toxicity, and amenability of low-cost and large-scale production. Platinium and palladium nanoparticles (Pt/PdNPs) dispersed of carbon dots (CDs) was prepared as a microbial fuel cell (MFC) electrode. The Pt/PdNPs involved CDs sponges (Pt/PdNPs/CDs) were characterized by optic, microscopic, spectroscopic and electrochemical techniques. Pt/PdNPs/CDs enabled the catalytic reduction of oxygen at the cathode and the electron transfer to the anode. Pt/PdNPs/CDs electrode showed high OCP, current density and power density. Pt/PdNPs/CDs can be used as an alternative electrode for MFCs.
