摘要: The invention provides a TiZrO2 carrier and a precious metal/TIZrO2 catalyst and preparation and application of the TiZrO2 carrier and the precious metal/TIZrO2 catalyst, and belongs to the field of water processing technology and environment function materials. The ZrO2 is stable in chemical property, and not only is not soluble in alkaline solution, but also can exist in acid solution stably. However, the specific surface area of the ZrO2 is small, and generally is only about 20m2/g to 50m2/g, and due to the fact that when the ZrO2 is calcined, the ZrO2 can generate martensite transformation, the fact that molded products have no intensity is caused. The precious metal/TIZrO2 catalyst is a catalytic wet air oxidation catalyst which is corrosion resisting, high-temperature resisting, high in strength, and big in specific surface area, and uses zirconium oxide stabilized by titanium oxide as a carrier to support precious metal Ru and Pt with high activity and difficult to run off, and prepares the excellent catalytic wet air oxidation catalyst. The prepared catalyst maintains good form after the prepared catalyst runs for 242 h under a high-temperature high-pressure acid environment with the temperature of 260 DEG C, the pressure of 5.7 MPa and the potential of hydrogen (PH) value of about 3, and the performance is beneficial to the popularization of a zirconium oxide supported catalyst in the industrialized application of catalytic wet air oxidation. | TiZrO2载体和贵金属/TiZrO2催化剂及其制备与应用,属于水处理技术和环境功能材料领域。ZrO2化学性能稳定,不仅不溶于碱性溶液,而且可以在酸性溶液中稳定存在;但其比表面积较小,通常只有20~50m2/g左右,且由于煅烧时会发生马氏体转变,导致成型产品没有强度。本发明公开了一种耐腐蚀、耐高温、高强度、大比表面积的催化湿式氧化催化剂,以氧化钛稳定的氧化锆为载体,负载高活性且不易流失的贵金属Ru、Pt,制备出优良的催化湿式氧化催化剂;所制催化剂在260℃、5.7MPa、pH≈3高温高压酸性环境中运行242h后形态完好,这有利于氧化锆负载型催化剂在催化湿式氧化工业化应用中进行推广。
