Special Issue Information

Dear Colleagues,

The rapid consumption of fossil fuels has caused increasing instances of climatic issues and energy crises, which leads to the urgent demand for developing sustainable and clean energies. The development of electrochemical energy conversion and storage devices offers opportunities to address global energy challenges. The development of advanced electrocatalyst technology is based on the exploration of many scientific problems, including in-depth understanding of electrocatalytic mechanisms, design and synthesis of advanced catalysts, design of electrolytic cells, exploration of catalytic reaction possibilities, and advanced characterization techniques. The scope of this Special Issue, entitled “Nanomaterials towards Electrocatalysis”, is to offer latest cutting-edge research and developments of electrocatalysis for energy conversion. In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Electrocatalysts for fuel cells and water electrolysis;
  • Electrochemical conversion of CO2, N2, CH4 and other small molecules;
  • Electrocatalysis mechanistic studies;
  • Electrolyzer reactor design;
  • Advanced characterization techniques for electrocatalysis.

Transition metal sulphide electrocatalytic materials possess the bright overall water-splitting performance of practical electrocatalytic technologies. In this study, an amethyst-like MoS2@Ni9S8/Co3S4 rod electrocatalyst was constructed via a one-step hydrothermal method with in-situ-grown ZIF-67 nanoparticles on nickel foam (NF) as a precursor. The rational design and synthesis of MoS2@Ni9S8/Co3S4 endow the catalyst with neat nanorods morphology and high conductivity. The MoS2@Ni9S8/Co3S4/NF with the amethyst-like rod structure exposes abundant active sites and displays fast electron-transfer capability. The resultant MoS2@Ni9S8/Co3S4/NF exhibits outstanding hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) electrocatalytic activities, with low overpotentials of 81.24 mV (HER) at 10 mA cm−2 and 159.67 mV (OER) at 50 mA cm−2 in 1.0 M KOH solution. The full-cell voltage of overall water splitting only achieves 1.45 V at 10 mA cm−2. The successful preparation of the amethyst-like MoS2@Ni9S8/Co3S4 rod electrocatalyst provides a reliable reference for obtaining efficient electrocatalysts for overall water splitting. Full article
