Highly Dispersed

Ultrathin monolayer HNbWO6 nanosheets were rapidly synthesised with triethanolamine as a stripping agent in just a few minutes. These obtained highly dispersed nanosheets suspensions exhibit an efficient photocatalytic H2 evolution performance under simulated sunlight irradiation.

Interfacial Separation

The addition of CeO2 can increase the activity of rutile for CO2 photoreduction under simulated sunlight irradiation because of the presence of Ti defects at the CeO2–rutile interfaces, and this is beneficial to the interfacial separation of photogenerated charge carriers.

Spr Effect

Water pollution caused by intensive use of organic dyes has become an increasingly serious problem recently. Green and efficient processes are desperately needed to remove persistent organic pollutants from waste waters. Herein, Ag nanoparticles loaded ZnO hollow microspheres were synthesized through a simple solvothermal method and used as a photocatalyst for dye degradation. The calculated band gap of Ag/ZnO — 5% (2.97[Formula: see text]eV) is much narrower than that of pure ZnO (3.37[Formula: see text]eV). The obtained Ag/ZnO samples show a remarkable photocatalytic activity in photodegradation of Rhodamine B (RhB) under simulated sunlight irradiation. The degradation efficiency of RhB for Ag/ZnO — 5% is 98.8% after 100[Formula: see text]min irradiation while only 52.8% degradation rate is obtained over pure ZnO. The enhancement is attributed to the exposed active ZnO (001) plane and the surface plasmon resonance (SPR) effect of Ag nanoparticles that promote the separation of photogeneated electrons and holes.
