ChemInform Abstract: Preparation of Yolk‐Shell and Filled Co9S8 Microspheres and Comparison of Their Electrochemical Properties. Issue 19 (13th May 2014) - Ko, You Na
Abstract Phase‐pure Co9S8 yolk‐shell microspheres are prepared by ultrasonic spray‐pyrolysis of solutions containing Co(NO3)2 and sucrose at 800 °C (leading to the formation of Co3O4 yolk‐shell microspheres) followed by sulfidation with thiourea as the sulfur source (10% H2/N2, 350 °C, 6 h).
