Pore structure, interface properties and photocatalytic efficiency of hydration/dehydration derived TiO2/CNT composites

- Intimate contact between TiO2 and CNT is crucial in photocatalysis.
- CNTs remain tangled in self-standing bundles through strong van der Waals forces.
- Liquid N2 porosimetry as a tool to assess the mixing quality and catalytic efficiency.
- Caffeine photocatalytic degradation is correlated with TiO2/CNT mixing quality.
- Caffeine removal is improved in materials with wide micropores.
