A New Synthesis of Highly Dispersed MoS 2 Nanoparticles on Ketjenblack Carbon for Sustainable Oxygen Reduction Reaction

In this paper, we describe a facile new synthetic method for making highly dispersed molybdenum disulfide nanoparticles (~ 3 nm) on Ketjenblack carbon (MoS2/KC) via particle incorporation and sequential sulfidation. The MoS2/KC nanocatalyst obtained showed a good onset potential value (0.83 V), high durability, and excellent methanol tolerance for the oxygen reduction reaction. We report a simple method for making highly dispersed molybdenum disulfide nanoparticles (~ 3 nm) on Ketjenblack carbon support for sustainable oxygen reduction reactions with good onset potential, high durability, and excellent methanol tolerance.
