Synthesis Of Immobilized Nano-Tio2 For
Photocatalytic Degradation Of
Phenol.
Masters thesis, Universiti Sains Malaysia.
Abstract
The presence of phenol in wastewater represents a significant environmental
problem. Due to some drawbacks in conventional wastewater treatment,
photocatalysis provides an interesting alternative. Immobilized nano-TiO2
photocatalyst was successfully synthesized using modified sol gel method and was
investigated for photocatalytic degradation of phenol in a batch reactor. The
synthesized photocatalyst composition was developed using nano-TiO2 as
photoactive sites and zeolite as adsorbent, all immobilized onto support using binder.
A series of experiments were conducted to investigate the influence of
Degussa P25 in alkoxide sol and the suitable type of each component for the role of
immobilized nano-TiO2 catalyst components. TiO2 based adsorbent photocatalyst
which using the concept adsorbent concentrate target compound near TiO2 was
applied to overcome the drawback of the high energy needed of TiO2 application.
The purpose of using immobilized catalyst is to prevent the need of costly separation
after treatment and due to the ability of reused catalyst.
