Synthesis of composite WO3/TiO2 nanoparticles by flame-assisted spray pyrolysis and their photocatalytic activity

Highlights
- We synthesize composite WO3/TiO2 nanoparticles using spray pyrolysis method.
- We varied the concentration of AMT and TTIP in wide range ratio (0-100 wt%).
- Photodegradation drastically improvement when the ratio of AMT below than 25 wt%.
- When the ratio of AMT of above 25 wt%, the photodegradation slightly improvement.
- The changes of photodegradation rate are influenced by band gap energy and surface area.
