A simple, facile in situ reduction approach is reported for the synthesis of Pd- nanoparticle-decorated phosphotungstic acid （PTA）-MIL-100（Fe） nanocomposites （Pd-H3PW12040-MIL-100（Fe）, denoted Pd-PTA-MIL-100（Fe））. During the in situ synthesis, PTA is encapsulated into the matrix of MIL-100（Fe） and serves as a UV-switchable reducing agent, resulting in highly dispersed Pd NPs. Using the photocatalytic degradation of pharmaceuticals and personal care products as model reactions, the ternary Pd-PTA-MIL-100（Fe） hybrids exhibited enhanced photocatalytic activity compared with their foundation matrices, the binary PTA-MIL-100（Fe） nanocomposite. Based on photoelectrochemical analyses, the improved photocatalytic performance can be attributed to the well-known electronic conductivity of the Pd NPs, the fast electron transport of PTA, the intense visible-light absorption of MIL-100（Fe）, and the matched energy levels of the three components： MIL-100（Fe）, PTA, and Pd NPs. Importantly, almost no Fe and W ions were leached from the samples during the reaction, demonstrating the photostability of the Pd-PTA-MIL-100（Fe） composite. In addition, possible photocatalytic reactions mechanisms have also been investigated.

The strontium modified waste FCC catalyst was prepared by magnetic stirring method and characterized by Xray diffractometry(XRD),UV-Vis diffuse reflectance spectrometry(DRS),X-ray photoelectron spectroscopy(XPS)and scanning electron microscopy(SEM).Meanwhile,its photocatalytic denitrogenation performance was evaluated in terms of its ability to degrade the N-containing simulation oil under visible light.A mixture of strontium nitrate solution(with a concentration of 0.5 mol/L)and waste FCC catalyst was calcined at 400℃for 5 h prior to taking part in the photocatalytic denitrogenation *** test results showed that the photocatalytic degradation rate of pyridine contained in simulation oil in the presence of the strontium modified FCC catalyst could reach 92.0% under visible light irradiation for 2.5 h.

Ca3R2–xWO9：xEu^3＋（R=Y, Gd） red-emitting phosphors were prepared by solid state reactions. These samples were characterized by differential scanning calorimetry and thermogravimetry analysis（DSC-TGA）, X-ray diffraction（XRD）, Fourier transform infrared spectroscopy（FTIR）, photoluminescence（PL） and field emission scanning electron microscopy（FE-SEM） analyses. The optimum sintering temperature for these phosphors was 1100 ℃, and the optimum sintering time was 2 h. The optimum doped concentration of Eu^3＋ in Ca3Y2–xWO9：xEu^3＋ and Ca3Gd2–xWO9：xEu^3＋ were x=1.5 and x=1.1, respectively. These phosphors could be excited by near-UV light of 394 nm and blue light of 465 nm, and showed strong red emission line at 612 nm（^5D0→^7F2）, which indicated that Ca3R2–xWO9：xEu^3＋（R=Y, Gd） were promising red candidates for white LED.
