Title
Molybdenum phosphide-graphite nanomaterials for efficient electrocatalytic hydrogen production
Abstract

•We prepared a new composite nanomaterial containing MoP and graphite.•We reduced particle sizes via ball milling which increased the HER activity.•Characterization confirmed nanomaterial morphology, size, and improvement in surface area.•The new materials provide synergistic, stable, and efficient catalysis for HER.

Clean hydrogen energy technology is an alternative to a fossil fuel-based energy economy. Efficient and economical catalysts are necessary for large-scale hydrogen generation. We report MoP and MoP-graphite nanosheets prepared by ball milling commercial compounds as efficient electrocatalytic materials for hydrogen generation via the hydrogen reduction mechanism. The hydrogen generated through electrochemical catalysis was evaluated using gas chromatography. The effects of ball milling time and proportions of MoP-graphite nanosheets on electrocatalytic activity were investigated. The new nanomaterials were characterized using powder XRD, SEM and BET surface area measurements. The results suggest superior electrocatalytic performance with a balance of ball-milled MoP and graphite. A Tafel slope of 63 mV/dec was obtained for this new material.
