Abstract

ZnTa2O6, ZnNb2O6, MgTa2O6 and MgNb2O6 pseudo-binary oxide nanomaterials were synthesized through the hydrothermal method at 250 °C. Obtained materials were characterized by X-ray diffraction, UV-VIS measurements, field emission-scanning electron microscopy and atomic force microscopy techniques. XRD results show that the single phases of ZnTa2O6, ZnNb2O6, MgTa2O6 and MgNb2O6 pseudo-binary oxides nanomaterials were obtained, no thermal treatment being required. The values for the optical band gap of each material are settled in the range 3.60–3.80 eV. The anticorrosion characteristics of the obtained compounds were also evaluated after deposition on carbon steel in 0.5 M Na2SO4 media by open circuit potential measurements and potentiodynamic polarization technique with Tafel representation. The inhibition efficiency of pseudo-binary oxides deposited on carbon steel electrode was in the range 37–59.17%, promising for improvement of the anticorrosion properties.

水热合成具有防腐性能的ZnTa2O6、ZnNb2O6、MgTa2O6和MgNb2O6伪二元氧化物纳米材料

采用水热法在250℃下合成了ZnTa2O6、ZnNb2O6、MgTa2O6和MgNb2O6伪二元氧化物纳米材料。通过x射线衍射、紫外-可见测量、场发射扫描电子显微镜和原子力显微镜技术对所得材料进行了表征。XRD结果表明，制备得到了单相ZnTa2O6、ZnNb2O6、MgTa2O6和MgNb2O6伪二元氧化物纳米材料，无需进行热处理。每种材料的光学带隙的取值范围为3.60-3.80 eV。在0.5 M Na2SO4介质中，通过开路电位测量和Tafel表示的动电位极化技术，对所得化合物沉积在碳钢上的防腐性能进行了评价。在碳钢电极上沉积的伪二元氧化物的缓蚀效率在37 ~ 59.17%之间，有望提高碳钢电极的防腐性能。
