By heating a simple system only composed of zinc acetate, hexamethylenetetramine (HMT) and water at 50 degrees C, layered basic zinc salt (LBZS) nanobelts were fabricated. The nanobelts could form a self-standing film by vacuum filtration, and then the film was transformed into a porous ZnO self-standing film by calcining at 200 degrees C. If the LBZS precursor was heated at 90 degrees C or 500 degrees C directly, ZnO microtubes or bottle like microstructures were obtained, respectively. By taking advantage of formaldehyde and ammonium, two products of HMT hydrolysis, Ag nanoparticles were deposited on the nanobelts to form an LBZS/Ag composite film. In the following calcination at 200 degrees C, a ZnO/Ag nanocomposite self-standing film was produced. The ZnO/Ag nanocomposite film exhibited a much higher photocatalytical ability than the pure ZnO film and other ZnO microstructures.
