Hydrothermal preparation of Nb-doped NaTaO3 with enhanced photocatalytic activity for removal of organic dye

doi:10.1016/j.cjche.2021.05.037

摘要/Abstract

摘要： The construction of efficient photocatalysts has received much attention in wastewater treatment. In this study, Nb-doped NaTaO₃ was prepared with different doping ratio by a facile hydrothermal method. The prepared catalysts were analyzed by X-ray diffraction, scanning electron microscopy, Brunauer-Emmett-Teller (BET) theory, ultraviolet–visible diffuse reflectance spectroscopy. Then the synthesized catalysts were employed to degrade a model pollutant, methylene blue (MB), under a 250 W mercury lamp. The characterization tests confirm that Nb was successfully doped into the crystal structure of NaTaO₃ and the modified NaNb_xTa_1-xO₃ (x is the doping ratio; x = 0.25, 0.5, 0.75) samples were formed, which were in regular cubic shapes just like pure NaTaO₃. The synthesized NaNb_xTa_1-xO₃ (x = 0.25, 0.5, 0.75) had improved specific surface area and narrowed band gaps compared with pure NaTaO₃. In photocatalytic degradation experiments, NaNb_0.75Ta_0.25O₃ presented the best photocatalytic activity ascribed to the narrow band gap and the high surface area, degradating 95.7% of MB after 180 min of reaction, which was even twice the ability of pure NaTaO₃. Besides, the effects of possible inorganic anions and cations in wastewater on photocatalytic degradation were investigated. Electron spin resonance (ESR) tests and capture experiments were also conducted and a possible photocatalytic mechanism was proposed. This work provides a direction for constructing superior NaTaO₃-based photocatalysts to be widely utilized in environmental protection.
