A Review on Modification of Zeolite for Photocatalytic Applications

Abstract

Zeolites are microporous crystalline alumina-silicate materials, widely used as catalysts, ion exchangers and adsorbents due to their chemical structure and surface properties. The unique properties of zeolite such as high adsorption capacity and cation exchange make it interesting to be used as a support material. This review article presents the details of various researches of zeolite used as photocatalyst in photocatalytic application. The modifications of zeolite using several methods are described in details for photocatalytic enhancement. The effect of zeolite nanoparticles in membrane fabrication also provided in this article. Furthermore, the efficiency of zeolite used as adsorbents and photocatalyst in the photocatalytic application also presented.

Mechanism of Membrane Fouling in Hybrid Membrane Photocatalytic Reactor for Palm Oil Mill Secondary Effluent Treatment

“…The treated palm oil mill effluent (POME) through biological treatment results in what is termed palm oil mill secondary effluent (POMSE). POMSE, a secondary effluent treated from the raw POME, exhibits high turbidity, color intensity, and an organic load of biochemical oxygen demand (BOD) that still fails to meet the environmental department's discharge requirements, emitting an unpleasant odor due to its elevated phosphate and nitrogen content [11][12][13][14][15]. As a consequence, it…”
