We have developed a simple, green synthetic method for producing metal and mixed-metal oxide nanoparticles. Over 50 different nanomaterials have been synthesized using this two-step, solvent deficient process in which (1) a solid metal salt or mixture of salts is ground with a solid base to produce a solid precursor that is (2) calcined at relatively low temperatures. Several of the method's products, including mesoporous Al2O3 and La-doped Al2O3, are being used as catalyst supports. These supports have been characterized using TEM, XAFS, and XRD (both Rietveld and PDF) methods. The XAFS and XRD data were obtained at high-energy accelerator facilities. The results of these structural analyses will be presented along with the postulated mechanism behind this extremely versatile synthetic method.
