Abstract
Synthesis is the base of experimental chemistry. Herein, monodisperse K₃PMo₁₂O₄₀▪nH₂O polyoxometalates with different morphologies have been reachedby tuning synthetic conditions of the K/POM ratio, stirring speed and time, and reaction temperatures. Among these factors, the K/POM ratio is identified mostcritical in morphological controls of the K₃PMo₁₂O₄₀▪nH₂O particles, altering them from cubes to spheres. Additionally, morphological transformations were identified through a self assembly and Ostwald ripening process, setting a generic synthetic strategy for the POM systems. Such synthetic strategies have substantial applications in catalytic or surface demanding fields requiring POM materials with controlled morphology.
