Electrochemical Hydrogen Generation by Biomass Electrolysis with Pt_mos2 Electrode

Abstract

Here we report the performance in lignocellulosic material oxidation of Pt_MoS₂-based electrode. The prepared nanocomposite, synthesized according to a “wet chemistry” approach, was broadly characterized: SEM-EDS images and XRD spectrum indicate the formation of nanoparticles with a few nanometers size dispersed on MoS₂ nanosheets. The sample was tested for the oxidation of lignocellulosic biomass in alkaline solutions. A very small overpotential is demonstrated (0.17 V) showing that such process could significantly reduce the cost of generating hydrogen reducing the energy required for the anodic oxidation process.
