Example:

Dehydration

By removing water and/or hydroxide groups from a compound, you can often perform redox chemistry and maintain a structural framework not accessible using conventional synthesis approaches

Examples :

Ti ₄ O₇ (OH)₂* nH₂O --------→ TiO₂ (B) (500 ° C)

2KTi ₄ O₈ (OH) * nH₂O--------→ K₂ Ti ₈ O₁₇ (500° C)
