Influences of Aeration and pH on Activities of HZSM-5 Supported TiO₂

Abstract:

Aeration and pH of methyl orange solution were adjusted to investigate the influences on photocatalytic degradation activities of TiO₂/HZSM-5. Degradation rate was enhanced when applying air into the solution. When air flow rate increased from 0 to 150 ml/l, methyl orange degradation rate increased from 47% to 55%. Further increase of air flow rate had nearly no influence on degradation rate. Degradation rate performed strong dependence on pH value of methyl orange solution. Acidic situation was favorable for methyl orange degradation, whereas methyl orange degradation in basic situation was comparatively weak. Photocatalytic degradation of methyl orange decreased with increasing of pH value.
