Heat treatment can significantly impact the properties of nanomaterials in various ways:
1. Structural Changes: Heat treatment can induce phase transitions and grain growth, leading to changes in the material's structure and morphology. 2. Chemical Composition: By controlling the atmosphere during heat treatment, it is possible to induce oxidation, reduction, or other chemical reactions, thereby altering the material's composition. 3. Surface Properties: Heat treatment can modify the surface characteristics of nanomaterials, such as surface energy and reactivity, which are critical for applications in catalysis and sensing.
