[Display omitted] • ZnS superhydrophobic coating was prepared on Zinc Substrate. • solvothermal method is environmentally friendly and controllable in appearance. • This coating exhibited excellent physical self-cleaning performance. • This coating displayed outstanding chemical self-cleaning performance. The superhydrophobic photocatalytic self-cleaning coating has both physical and chemical self-cleaning properties, which has attracted wide attention of researchers in recent years. In this paper, ZnS superhydrophobic coating was prepared on the surface of zinc substrate by economic and environmental friendly solvothermal method and chemical modification method. By means of EDS, X-ray diffraction and X-ray photoelectron spectroscopy (XPS), it was proved that ZnS superhydrophobic coating was successfully formed on the surface of zinc substrate after solvothermal reaction and chemical modification. Moreover, the morphology of the coating surface was observed to be nanobeam by scanning electron microscopy, and the Cassie contact state was formed when water droplets contacted with the superhydrophobic coating surface containing ZnS nanobeam. In addition, the physical and chemical self-cleaning properties of ZnS superhydrophobic coatings were tested and their principles were explored. The results show that the nanobundle ZnS superhydrophobic coating has excellent physical and chemical self-cleaning properties. [ABSTRACT FROM AUTHOR]

• Morphology transition contributes to a perfect synergistic effect. • RGO enhances conductivity, rate capacity and cycling stability of composite. • Novel-innovative synthetic route decreases the energy consumption. • FeCO 3 and Fe 3 O 4 -RGO perform LIBs anodes improving product utilization. • Fe 3 O 4 -RGO exhibits a satisfied capacity of 925.3 mAh g−1 and 68.8% retention. In this paper, broccoli-like multichannel FeCO 3 microspheres were synthesized via one-pot hydrothermal process at low temperature. Then, a successful phase and morphology transformation from FeCO 3 to Fe 3 O 4 was realized to form the Fe 3 O 4 -RGO composites via a low temperature hydrolysis reaction in the presence of graphene and hydrazine. The multichannel structure of FeCO 3 microspheres benefits for the permeation of alkaline solution, improves the dispersion of Fe2+ and further makes Fe 3 O 4 homogeneously anchored on RGO sheets. Therefore, the Fe 3 O 4 -RGO composites show a satisfied property of 925.3 mAh g−1 at 100 mA g−1. Moreover, this anode material still delivers capacity of 636.1 mAh g−1 after 1000 cycles at 500 mA g−1. This work provides a new route for synthesizing metal oxide and their composites, which will find potential application in the field of energy storage. [ABSTRACT FROM AUTHOR]
