A simple, practical, inexpensive process for producing novel inorganic catalysts, nanocatalysts, and other nanophase materials possessing unique chemical and physical properties is described. A microbial reagent is incubated in a liquid medium to synthesize an extracellular precipitate. This extracellular precipitate may then be further processed by any of a variety of techniques to alter or improve its chemical and physical properties. The various factors that can affect and control the properties of the nanophase materials, such as the selection and preparation of the microbial reagent, the nature of the incubation conditions, and the utilization of post-incubation treatments, and the types of nanophase materials that can be prepared by this invention, are described.
