Treading on eggshells: WO 3 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.
