We report an efficient molybdenum disulfide (MoS2) supported by thermally reduced graphite oxide (TRGO) for hydrogen evolution reaction (HER). The TRGO-MoS2 composite exhibits excellent catalytic activity with a low overpotential of -0.23 V, which is almost three and seven times lower than those of precursor MoS2 and GO-MoS2. The high performance of HER attributes to TRGO, providing a conducting network for fast electron transport from MoS2 to electrodes. The composite also shows high stability in which the overpotential remains constant after 1000 cycles and strong durability after 48 h, demonstrating a synergistic effect of MoS2 and TRGO for efficient HER.
