A facile route for the synthesis of nickel foam modified WSe2:CdS nanohybrid as an efficient catalyst for hydrogen evolution reaction (HER)

Abstract

Nickel foam was synthesized via a easy and time consuming method with the help of microwave, the nickel foam was then modified with very impressive rod shaped nanoparticle WSe2-CdS. The pores of the nickel foam are very clear and uniform in size with the nanoparticle attached in the surface of the foam. The prepared nanohybrid foam (Nifoam@WSe2-CdS) shows good performance towards hydrogen evolution reaction with small onset potential of-0.30 V and very low tafel slope that is 44 mV/dec. The electrocatalyst was prepared with earth abundant material with low cost of synthesis. Prepared electrocatlyst shows high durability over acidic medium for several time periods with unchanged electrochemical behavior.
