Hydrogen evolution reaction (HER) through electrocatalytic water splitting is regarded as a promising route to produce hydrogen in a large scale. Molybdenum disulfide (MoS2) has been reported as a transition metal electrocatalysts, but generally with a poor activity, e.g. 540 mV overpotential at 10 mA cm−2 and Tafel slope value of 84 mV dec−1. A 3D MoS2-rGO@Mo nanohybrids, a three-dimensional MoS2...
A facile refluxing strategy in aqueous solution was engaged to synthesize ultrashort rice-like CuO nanorods/reduced graphene oxide (CuO-NRs/rGO) composite. The result of the high-resolution transmission electron microscopy shows that the as-synthesized rice-like CuO nanorods have a uniform size of about 8 nm in width and 28 nm in length and are homogenously dispersed on rGO nanosheets. The CuO nanorods...
