Dyes Degradation

Sodium niobate catalysts with different morphologies of nanowires and microcubes have been prepared by hydrothermal method. The photocatalytic performance of NaNbO3 nanowires and microcubes was evaluated by degradation of rhodamine B (RhB) and cationic red X-GRL (CRX). The photodegradation reaction of organic dyes is shown to be kinetically first-order. The as-prepared NaNbO3 nanowires exhibit higher photo-catalytic activity for organic dyes degradation than NaNbO3 microcubes, which is attributed to the larger specific surface area and ferroelectric phase structure.

Crystal Growth Condition

It is known that cracking occurs in Barium-Sodium Niobate, Ba 4 Na 2 Nb 10O30 (BNN), during Czochralski (cz) growth. This is due mainly to lattice distortions associated with the ferroelectric phase transition. We have studied the cz crystal growth condition for BNN without cracking, and found that high quality single crystals of BNN without cracking can be grown by using Gd-doped starting melt, i.e., Ba 4 Na 2 Nb 10O30-Ba3NaGdNb10O30 solid solution. In order to confirm the effect of Gd doping on the crystalline quality, Gd concentrations were measured by ICP for both the cz single crystal sample and the starting powder material. Gadlinium concentration in the as-grown crystal was about 0.195 mol %, nearly the same as that (2.0 mol %) in the starting material. Dielectric constant along c-axis, ε33, was measured at temperatures from 300 K to 870 K. The experimental result revealed that ε33 of the single crystal is about two times larger than that of BNN single crystal without Gd impurity in the temperature range from 300 K to 650 K.
