Shape-controlled synthesis of SrNb2O6 crystallites by an electrochemical process assisted with surfactants

The combination of electrochemical process with a soft-template can be successfully used in preparing SrNb₂O₆ crystallites with different particle size and morphology. In the absence of organic additives, SrNb₂O₆ powders are irregular-shaped aggregates. The introduction of hexadecyl trimethyl ammonium bromide (CTAB) in electrolytic solution will guide SrNb₂O₆ primary grains to form homogeneous microspheres, but the presence of polyvinylpyrrolidone will weaken the aggregation effect of CTAB spherical micelles and tend to promote the formation of bunched SrNb₂O₆ microrods.
