The molecular self-assembled nanohybrids CdS QDs-POM-Au NPs can be synthesized by a convenient, efficient and environmentally friendly strategy. The POMs, which function as the reducing, encapsulating molecules and bridging molecules, not only successfully realize the strong coupling of the different nanoparticles, but also enhance the electron transfer among the components of the nanohybrids. More importantly, the present nanohybrids can effectively harvest visible light and show synergistic photocatalytic activity both in photoproduction of hydrogen and degradation of organic pollutants. This synthesis method is versatile and promising for the design and development of other new solar energy hybrid systems.

The tri-component hybrid CdS nanorods (NRs)/Au nanoparticles (NPs)@polyoxometalate (POM) was successfully prepared by a facile, efficient and green method. The structural properties and component analysis were studied by Transmission electron microscopy (TEM), X-ray Diffraction (XRD) and UV-Vis spectra. The POMs sever as not only reductant and bridge molecules, but also as co-catalyst to play an important role in the photocatalytic process. The as-prepared nanohybrid shows obviously enhanced photocatalytic activity toward photocatalytic evolution of hydrogen.

Liquid−liquid equilibria of the aqueous twophase systems of the ionic liquid (IL) 1-butyl-3-methylimidazolium tetrafluoroborate and sodium dihydrogen phosphate/ disodium hydrogen phosphate or their mixtures have been determined at 298.15 K, 303.15 K, and 308.15 K. The nonlinear equation developed by Merchuk was used to correlate the experimental binodal data. The two-phase regions gradually expand with the increase of the percentage of Na 2 HPO 4 in the salt mixtures. It was also shown that the two-phase region decreases along with the temperature increases. The tie-line data were correlated by Othmer−Tobias and Bancraft equations. It was found that these equations fit the experimental data well. The temperature dependence on tie lines has been discussed. The effect of the concentration of the salt mixtures on binodal curves and tie-line data has also been discussed.
