The optical functionalized YVO4: Eu3+/MCM-41 mesoporous composites were prepared by hydrothermal method. The structure, morphology, luminescence properties and fluorescence dynamics were studied systemically. The compared studies of the luminescence properties of YVO4: Eu3+/MCM-41 with YVO4: Eu3+ nanocrystal were performed. The results show that the YVO4: Eu3+/MCM-41 retains high ordered mesoporous structure of MCM-41. In YVO4: Eu3+/MCM-41, the intrinsic excitation bands of Eu3+ disappears and the lifetimes of Eu3+ become short. The luminescent efficiency of YVO4: Eu3+/MCM-41 is higher than ones of the YVO4: Eu3+ nanocrystal.

The reactive red 3 was degraded by catalytic wet oxidation process over Fe-RH-MCM-41 prepared by Direct Hydrothermal Technique (DHT) at Si/Fe molar ratio of 10 using silica from rice husk. The extended reaction conditions were studied as a function of reaction temperatures, initial H2O2 concentrations and initial pH of solutions designed by Box-Behnken design (BBD) based on Response Surface Methodology (RSM) to achieve the optimal condition and interaction of independent variables. The characterizations of catalyst were studied by XRD, BET surface area and TEM to explain the morphology of surface and to confirm the hexagonal structure. The results showed the 2theta peak can be indexed to hexagonal lattice that also confirmed by TEM result and surface area about 650 m2/g. All of independent variables showed significant on the degradation of reactive red 3 except for initial H2O2 concentration.
