Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
The copper exchanged CuZSM-5 was used as support for TiO2 through solid state dispersion. Photocatalytic activity and adsorption ability of TiO2, and the function of CuZSM-5 to the photocatalytic properties of TiO2 were investigated. The photocatalytic degradation process was conducted after adsorption equilibrium was reached. As TiO2 concentration increased from 50 mg/1 to 250 mg/1, photocatalytic methyl orange degradation rate also increased from 28.6% to 54.6%. The concentration of TiO2 in the experiments was set as 250 mg/1. TiO2-CuZSM-5 composite prepared by solid state dispersion was mixed at different TiO2 and CuZSM-5 ratios. The TiO2-CuZSM 5 composite had low photocatalytic activity compared with pure TiO2. The introduction of copper ion into TiO2 photocatalyst might have negative effect on the performance of TiO2.
