What are Ionic Nanomaterials?
Ionic nanomaterials are a class of nanomaterials that possess ionic properties at the nanoscale. These materials often consist of metal oxides, metal sulfides, or other compounds containing ionic bonds. At the nanoscale, these materials exhibit unique properties compared to their bulk counterparts, making them particularly interesting for various applications.
Sol-gel method: This involves the transition of a system from a liquid "sol" (mostly colloidal) into a solid "gel" phase.
Precipitation method: In this method, soluble precursors react to form an insoluble product, which precipitates out of the solution.
Hydrothermal synthesis: This technique involves using high-pressure and high-temperature aqueous solutions to grow crystals.
Electrochemical deposition: This process uses an electrical current to reduce metal ions from a solution and deposit them as a thin film or nanoparticles.
High surface area: The nanoscale dimension provides a large surface area to volume ratio, enhancing reactivity.
Enhanced optical properties: These materials can exhibit unique optical characteristics, such as quantum confinement effects.
Electrical conductivity: Some ionic nanomaterials can show improved electrical conductivity.
