Presentation Transcript

  1. Graphene-based nanocompositephotocatalyst

  2. Conference review Benzyl alcohol assisted sol-gel (Markus Niederberger, ETH Zurich) First discover(2002): Metal chloride-benzyl alcohol reaction ← Highly crystalline anatase TiO2 nanoparticles at low-temperaure of 40ºC Surfactant-free process has futher advantage on low-temperature processing 40ºC TiO2 Mechanism proposed later Hydrolysis of metal precursors in non-aqueous condition 120ºC VO5 100ºC WO6

  3. Conference review 2. PEO assisted sol-gel (H Cui) Combination of benzyl alcohol solvent & PEO epoxide ← LiFe5O8 nanoparticle After gelation of LiCl and FeCl3 at RT, NPs are obtained by thermal annealing Crystalline spinel structure at just 150ºC Mechanism of epoxide-assisted sol-gel ※ Produced chloropropanol acts as dispersion agent
