When comparing chemical vapor deposition (CVD) and spray pyrolysis for the deposition of aluminum nanoparticles, several aspects should be considered, particularly concerning the size of nanoparticles produced using these methods. Here’s a detailed comparison:
### 1. **Mechanism of Deposition:**
- **CVD (Chemical Vapor Deposition):**
- CVD involves the chemical reaction of gaseous precursors which decompose on a substrate to form a solid
