- •
TiO2 promotes melon to form at 400 °C, whereas it forms at 500 °C for only melamine.
- •
The highest photocatalytic activity was achieved when calcination was performed at 400 °C.
- •
Coordinated N
TiN bonds were formed in MA/TiO2 (400) and disappeared at high temperature.- •
The surface area decreased and the pore size increased with increasing of temperature.
- •
Only MA/TiO2 (400) has a narrower band gap than pure g-C3N4.
