Abstract Nanomaterials, especially inorganic nanomaterials such as metal, metal oxide, metal sulfate, quantum dots, et al. With the basic properties of quantum dots significantly in the development of biomedical, catalytic, fuel cells, sensors and magnetic data storage were attracted. The term nano-crystal can be designed and synthesized nano-crystal morphology and composition to the understanding and extraction of nucleation and growth processes to be defined. The process of nano-materials in biomedical applications, catalysis, fuel cells and solar and magnetic data storage is key. This paper presents a comprehensive review of inorganic nanomaterials with controlled of germination and growth through the theory of controlled laboratory conditions, provide a brief account of the control of nano-iron oxide minerals during the synthesis process provides more chemistry. Moreover, similar mechanisms for control of nano-minerals are also clearly described. Spherical and rod iron oxide nanoparticles synthesized by co-precipitation and hydrothermal processes were examined. Then the FT-IR and SEM techniques were studied.
