In this work, a novel route is discussed to produce in one step ZnO/Burkeite powders by the\nmodified solution combustion method. The ZnO particles enhance the photocatalytic activity in the\ndegradation of Rhodamine B, in which Burkeite mineral acts as a support due to the pH-dependent\nmorphology of the particle aggregates of the as-synthesized powders. The X-ray diffraction (XRD)\ncharacterization shows the presence of a heterostructure: ZnO/Burkeite. The Scanning Electron\nMicroscopy (SEM) image shows a morphological dependence with the pH of the solution used for\nthe synthesis. The results show that the system with the highest degradation (92.4%) corresponds to\nthe case in which ZnO/Burkeite heterostructure was synthesized with a pH 11.
