Abstract Cobalt sulfide, a class of metal chalcogenide with tunable electronic structure and component distribution, has attracted considerable interest in renewable energy conversion utilization. In this work, we report facile, efficient scalable method to synthesize Co 9 S 8 supported on nitrogen sulfur co doped porous carbon (Co /N,S‐PC) hybrid from the annealing treatment coordination compound assembled by 2‐mercaptobenzimidazole, 4,4‐bipyridine cobalt salt. The heteroatom organic ligand could efficiently tune properties nanoparticles well‐designed carbon. Meanwhile interaction ligands provides platform for high dispersion . Owing synergetic effect, /N,S‐PC catalyst shows an admirable oxygen reduction reaction (ORR) activity E 1/2 0.804 V vs RHE, together good durability, tolerance methanol poisoning alkaline media.

Graphene-based materials have been widely studied in the field of supercapacitors. However, their electrochemical properties and applications are still restricted by susceptibility graphene-based to curling agglomeration during production. This study introduces a facile method for synthesizing reduced graphene oxide (rGO) nanosheets activated carbon based on olive stones (OS) with polyaniline (PAni) surface decoration development Several advanced techniques were used examine structural samples. The obtained PAni@OS−rGO (1:1) electrode exhibits high capacity 582.6 F·g−1 at current density 0.1 A·g−1, an energy 26.82 Wh·kg−1; thus, it demonstrates potential efficacious storage. In addition, this material remarkable cycling stability, retaining over 90.07% capacitance loss after 3000 cycles, indicating promising long cycle life. Overall, research highlights biomass-derived OS presence PAni rGO advance high-performance
