Graphitized carbon nitride (g-C3N4), as a simple and green photocatalytic material, has been widely used in photocatalytic degradation. However, the photocatalytic activity of g-C3N4 was inhibited by poor visible light absorption and high photocarrier recombination rate. Metal quantum dots (Qds)/g-C3N4 nanosheets coupled catalysts have attracted more and more attention in the Fenton advanced oxidation process due to their high charge mobility and more active sites. In this work, heterogeneous photocatalysts of Fe-Cu bimetallic oxide quantum coupled with g-C3N4 nanosheets were prepared. It shows high activity in Fenton and photocatalytic system. Under the optimal conditions, the removal efficiency of 50 ppm phenol reached 99% after 60 min. The removal efficiency of the catalyst for phenol did not decrease significantly after four cycles of experiments, and the catalyst had good stability. The experimental results show that the synergy between g-C3N4 semiconductor photocatalytic oxidation technology and heterogeneous Fenton advanced oxidation technology has great practical significance.

Synthesis and Characterization of Novel Inorganic MicroporousBeryllophosphates.-Hydrothermal syntheses at 150 • C under autogeneous pressure, starting from BeO, P2O5, MCl (MCl2) (M: Na+, NH+ 4 + K+, Ba2+, Sr2+, or Ca2+) and the templates cyclohexylamine, pyrrolidine, 1-butylamine or triethylamine result in the five microporous beryllophosphates (I)-( V). The homogeneous products, which do not contain any other phase than beryllophosphates, crystallize in a novel unique structure composed of tetrahedral BeO4 and PO4 basic building units. Their structures are stable up to 376-476, 408-570, 324, 429 and 720 • C for I, II, III, IV, and V, respectively. The materials show zeolite-like adsorption and ion-exchange properties (XRD, IR spectra, adsorption isotherms, DTA/TGA). -(YU, L.; PANG, W.; Collect.
