Inorganic nanomaterial is a kind of nanomaterial which is separated from the class of nanomaterials, referring to the composition of the main body is inorganic substances.
Inorganic nanomaterials include: nano-oxides, nanocomposite oxides, nanometallic and alloys, and other inorganic nanomaterials.
Inorganic nanomaterials have been widely used in various fields because of their excellent mechanical properties, optical properties, magnetic properties, electrical properties, catalytic properties, thermal properties and sensitive properties.

For example, BN nanotubes have been shown to chemisorb hydrogen. Fluorescent silica nanotubes are suggested to be useful in gene delivery. Protein biosensors based on biofunctionalized conical gold nanotubes have been fabricated. Ferroelectric phase transitions in template-synthesized BaTiO3 nanotubes and nanofibres have been examined. Ferroelectric and piezoelectric properties of biferroic BiFeO3 nanotube arrays have been studied. Highly efficient a-Fe2O3 nanotube chemical sensors based on chemiluminescence have been fabricated to detect H2S gas, using carbon nanotubes as templates. The a-Fe2O3 nanotubes have a high specific area and exhibit excellent sensitivity to reductive vapors and gases such as alcohol and hydrogen and superior electrochemical activity of 1415 mAhg-1 at 100 mAg-1(293K). LiCoO2, LiMn2O4 and LiNi0.8Co0.2O2 nanotubes, synthesized by the thermal decomposition of sol–gel precursors inside porous alumina templates have been examined as cathode materials for lithium ion batteries. Inorganic nanotubes have been integrated into metal-oxide-solution field-effect transistors which exhibit rapid field effect modulation of ionic conductance. Halloysite nanotubes can be employed as hollow enzymatic nanoreactors.
