Chul Min Sim, Young Jun Hong and Prof. Yun Chan Kang Electrochemical Properties of Yolk-Shell, Hollow, and Dense WO3 Particles Prepared by using Spray Pyrolysis ChemSusChem 6
Treading on eggshells: WO3 powders are prepared by using a one-step spray pyrolysis process. Different spray solutions are used (with or without sucrose), and particles with various morphologies (yolk-shell, hollow, and dense-structured) are achieved. The yolk-shell composite demonstrates electrochemical properties that are superior to the particles with dense and hollow structures at a high current density.
