|Title:||Phase controllable fabrication of zinc cobalt sulfide hollow polyhedra as high-performance electrocatalysts for the hydrogen evolution reaction||Authors:||Zhang, Bowei
|Keywords:||Engineering::Materials||Issue Date:||2017||Source:||Zhang, B., Yang, G., Li, C., Huang, K., Wu, J., Hao, S., . . . Huang, Y. (2018). Phase controllable fabrication of zinc cobalt sulfide hollow polyhedra as high-performance electrocatalysts for the hydrogen evolution reaction. Nanoscale, 10(4), 1774-1778. doi:10.1039/c7nr08097b||Journal:||Nanoscale||Abstract:||Structure and phase modulations allow the development of highly active, cost-effective and stable electrocatalysts for the hydrogen evolution reaction (HER) but are rather challenging. In this paper, Zn–Co–S hollow/porous polyhedra with controllable phases were fabricated via solvent-based sulfidation at room temperature followed by thermal annealing. The obtained hollow structure Zn–Co–S-300 with an amorphous phase exhibits excellent electrocatalytic HER activity, which is higher than crystalline Zn–Co sulfides annealed at a higher temperature. Zn–Co–S-300 also shows a long-term working stability (91.7% current density retention over 10 hours) in alkaline media. This work provides a feasible approach for the fabrication of homogeneous ternary transition metal sulfide (TMS) electrocatalysts via the Kirkendall effect towards high-efficiency HER applications.||URI:||https://hdl.handle.net/10356/141061||ISSN:||2040-3364||DOI:||10.1039/c7nr08097b||Rights:||© 2018 The Royal Society of Chemistry.
