The paper reviewed for research progress in controllable preparation nanomaterials. We also discussed the principle of controllable preparation nanomaterials by template method and formation mechanism of highly ordered aligned Al2O3 nanoporous. The theory and technique of template method of controllable preparation nanomaterials was described, which include Al2O3 nanoporous template methods, polymer template method and biology template method. Additionally, the Al2O3 nanoporous template methods can be divided into the eleetrochemieal-Al2O3 nanoporous template method, ＆ Sol-Gel synthesis method. According to the physical-chemical properties of material, the controllable nanomaterials with various structures can be prepared so long as electing a fit template and adopting a reasonable process.
