“…3a-c, the ZnO/rectorite sample has strong adsorption band in the visible region around 400-800 nm in contrast single ZnO. Importantly, the band gap absorption edge of the ZR-400 sample shows a markedly red-shift to the visible light region as compared to that of the ZnO, which could be interpreted in ZnO particles embedded on rectorite matrices, similar phenomenon had been reported by Li et al [20]. From the Fig.…”

In this work, zinc oxide/rectorite composites were synthesized by a sol-gel method. The methanol as sacrificial organics could be enhance the adsorption capability and photocatalytic reduction activity of U(VI) onto the zinc oxide/rectorite composites. In addition, the composite still showed the high photoreduction activity after four reaction cycles under visible light irradiation. On the basis of the experimental results and photoluminescence, the enhanced photoreduction activity could be attributed to charge-transfer-complex and the coupling effect of ZnO and rectorite in the composite.

The perforated ZnO nanoflakes with high degree of crystallinity and uniformity were synthesized via the hydrothermal-assisted sol-gel technique without any template. ZnCl 2 was used as a Zn-containing precursor, causing the oriented growth of particles. The observation of a hole on the facet of the as-synthesized particles was discussed in this work. XRD, TEM, and DRS were used to investigate the prepared powder and a simple mechanism was suggested to explain the hole formation on the surface of nanoflakes. As a result, the synthesized powder included pure ZnO with direct band gap energy of 3.24 eV. The range of particle size was within 1 lm in diameter and \50 nm in thickness. A circle hole with 300-500 nm in diameter was observed on the facet of the as-synthesized particles.
