Preparation of Au-sensitized 3D hollow SnO2 microspheres with an enhanced sensing performance

A controlled synthesis of three-dimensional Au-sensitized SnO2 hollow microspheres that composed of numerous nanorod subunits has been realized via a facile one-pot hydrothermal method without employing any templates or capping agents. The structural and morphological characteristics of the pure and Au-loaded SnO2 microspheres are revealed by X-ray diffraction, field-emission scanning electron microscope, and high resolution transmission...
