Hydrothermal technology for nanotechnology

Review on the criteria anticipated for the fabrication of highly efficient ZnO-based visible-light-driven photocatalysts

The hydrothermal technique provides an excellent possibility for processing of advanced materials whether it is bulk single crystals, or fine particles, or nanoparticles. The advantages of hydrothermal technology have been discussed in comparison with the conventional methods of materials processing. The current trends in hydrothermal materials processing has been described in relation to the concept of soft solution processing, as a single-step low energy consuming fabrication technique. Also some recent developments in multi-energy processing of materials such as microwave-hydrothermal, mechanochemical-hydrothermal, electrochemical-hydrothermal, sonar-hydrothermal, etc. have been discussed. An overview of the past, present and future perspective of hydrothermal technology as a tool to fabricate advanced materials has been given with appropriate examples.

Hydrothermal processing of materials: past, present and future

Hydrothermal conversion of calcite crystals to hydroxyapatite

TiO 2 /ZSM-5 composites were prepared from SiO 2 of rice husk ash and TiO 2 sol from hydrolyzed TiOSO 4 salt. The combined effect of these two materials greatly enhanced the photocatalytic decolorization of methylene blue dye solution. The instant decolorization of the dye solution in the dark by the composite, TiO 2 /ZSM-5 (wt ratio 1:1), resulted from the combination of the adsorption by ZSM-5 zeolite and TiO 2 nano-particles, and of Na 2 SO 4 salt adhering to the composite surface. As a strong flocculating agent, the SO 4 2− ion caused the precipitation of the dye onto the composite surface which consequently enhanced the photocatalytic decolorization of the dye under UV irradiation. The composite, TiO 2 /ZSM-5 (wt ratio 1:5), completely decolorized the methylene blue dye in 2.5 h, giving an equivalent performance to that of TiO 2 , P-25 powder.
