Platinum group metal-free (PGM-free) catalyst with different loadings was investigated in air breathing electrodes microbial fuel cells (MFCs). Firstly, the electrocatalytic activity towards oxygen reduction reaction (ORR) of the catalyst was investigated by rotating ring disk electrode (RRDE) setup with different catalyst loadings. The results showed that higher loading led to an increased in the half wave potential and the limiting current and to a further decrease in the peroxide production.

Iron aminoantipyrine (Fe-AAPyr), graphene nanosheets (GNSs) derived catalysts and their physical mixture Fe-AAPyr-GNS were synthesized and investigated as cathode catalysts for oxygen reduction reaction (ORR) with the activated carbon (AC) as a baseline. Fe-AAPyr catalyst was prepared by Sacrificial Support Method (SSM) with silica as a template and aminoantipyrine (AAPyr) as the organic precursor. 3D-GNS was prepared using modified Hummers method technique.

Article Synopsis
- - The study synthesized bimetallic catalysts using iron (Fe), cobalt (Co), nickel (Ni), and manganese (Mn) to improve the oxygen reduction reaction (ORR) performance for energy applications, with the specific method involving silica templates and an organic precursor (AAPyr).
- - Among the catalysts tested, the Fe-Mn-AAPyr variant showed the best results, outperforming others in half-wave potential and achieving a maximum power density of 221.8 ± 6.6 μWcm, while Co-based catalysts also improved with added metals.
- - In contrast, activated carbon (AC) served as a control and demonstrated the lowest performance in tests, achieving only 95.6 ± 5.
