Novel [Ni(2,20-bipy)3]Cl2 activated sepiolite clay composites have been successfully synthesized by ahydrothermal reaction method. The activated clays are endowed with much higher photocatalyticabilities than the raw one. Degradation ratios of rhodamine B and methyl orange under UV light werefound up to 99.8% and 95.4% within 120 min. Beside efficient dye degradations, a high H2 evolution rate of12.5 umol/g/h was reached by using the [Ni(2,20-bipy)3]Cl2/sepiolite composite as the catalyst. Coatingthe as-synthesized material on surfaces leads to extraordinary superhydrophobic and superoleophilicproperties. The cheap materials can be widely used in photocatalytic water purification and/or oil-watermixture separations.

Functional Sb2WO6 samples were prepared by a solvothermal method. XRD and XPS spectroscopy wereused to demonstrate structures of the as-prepared Sb2WO6 samples. And the morphologies werecharacterized via SEM and TEM. Different morphologies of the Sb2WO6 samples can be convenientlyachieved by simply changing the pH value. The Sb2WO6microspheres were obtained when the pH = 2. Apossible formation process of Sb2WO6 microspheres was proposed. The Sb2WO6 microspheres have highphotocatalytic activity and stability for the degradation of Rhodamine B. Moreover, the wettability ofSb2WO6 microspheres was also investigated. Results suggest that Sb2WO6 surface has highsuperhydrophobicity.

Construction of heterojunctions is conventionally regarded as the prevailing technique to enhance solardrivenphotocatalytic water splitting and photodegradation of pollutants. Herein, we report a noveldesign of a ternary Bi2O3/Bi/ZnIn2S4 system, which was facilely synthesized to satisfy these stringent criteriafor sunlight photocatalytic removal of organic and ionic pollutants and hydrogen evolution. Bi2O3/Bi/ZnIn2S4 could degrade 2,4-dinitrophenol (94.6%), tetracycline (96.5%), and Cr6+ (96.3%) effectivelyunder visible light and give a hydrogen production rate of 482.5 lmolg1h1 under visible light. Based on first-principles calculations and electrochemical results, our system could be identified as aZ-scheme. Photocorrosion of the sulfide is prohibited while the catalytic capabilities are simultaneouslybenefited due to lowered bandgap in light harvesting, internal electric fields in charge separations, andsurface plasmonic resonance enhanced electron boost.
