Pulsed laser ablation in liquid (PLAL) is one of the main techniques for synthesizing nanoparticle materials. The carbon target was dissolved in ultrapure water (UPW) and exposed to a Q-switched Nd: YAG laser (1064 nm) with a 6 ns pulse duration to produce carbon nanoparticles. In this sequence, the Nd: YAG laser beam was focused on the carbon surface. In the investigation of nanoparticles prepared by laser irradiation, the effect of different incident laser pulse energies (500, 1000 mJ) on particle sizes (52.09, 26.49 nm) was observed by atomic force microscopy (AFM), pH test, and lightning energy conductivity (EC) test of nanosolution was used to characterize the nanoparticles. Particle size was generated using (1000 mJ) laser pulse energy. The performance of the H-shaped microbial fuel cell (MFC) was also tested, using nanocolloids in a salt bridge. This work shows that (Co) NPs synthesized with an energy of (1000 mJ) pulsed laser can act as salt bridge catalysts to improve MFC power output.
