Question
What is nano material? Write the reaction involved in sol-gel process during hydrolysis.
✓
Answer
Nanomaterials are particles that have their size in the 1-100 nm range at least in one dimension.
We cannot see particles of nano materials from the naked eye.
The example of nanomaterials includes nano zymes, titanium dioxide, nanoparticles, graphene, etc. In the sol-gel process during hydrolysis, a metal alkoxide reacts with water to form a hydroxide and alcohol. A simplified generic reaction is : $MOR + H _2 O \longrightarrow MOH + ROH$ - M represents a metal atom (such as Si, Ti, etc.), - OROR is an alkoxide group, and - ROHROH is the resulting alcohol.
