Preparation method and application of three-dimensional macroporous oxide material
The invention discloses a preparation method and application of a three-dimensional macroporous oxide material. Comprising the following steps: dipping a template in a solution containing an oxide precursor, drying I, and roasting I to obtain a three-dimensional macroporous oxide material; the template is obtained by self-assembling phenolic resin particles. The three-dimensional macroporous oxide material is at least one of silicon dioxide, cerium dioxide, titanium dioxide, cobaltosic oxide, copper oxide, zinc oxide or ferric oxide; the morphology is regular, the aperture is uniform, and the structure is diversified. According to the method disclosed by the invention, the three-dimensional ordered macroporous oxide material with adjustable pore size, oxide type, metal crystallinity and material microstructure is controllably synthesized by utilizing the structural diversity and flexibility of the phenolic resin, so that the three-dimensional ordered macroporous oxide material has a good application prospect in the fields of catalysis, energy utilization and conversion, biological or chemical sensing and the like.
本申请公开了一种三维大孔氧化物材料的制备方法及应用。包括以下步骤：将模板浸渍于含有氧化物前驱体的溶液中，干燥I、焙烧I，得到三维大孔氧化物材料；模板为酚醛树脂颗粒自组装得到。三维大孔氧化物材料为二氧化硅，二氧化铈，二氧化钛，四氧化三钴，氧化铜，氧化锌或三氧化二铁中的至少一种；形貌规整，孔径均一，结构多样。本申请所述方法通过利用酚醛树脂的结构多样性和灵活性，可控合成孔径大小，氧化物类型，金属结晶度和材料的微观结构可调的三维有序大孔氧化物材料，使其在催化、能源利用与转化，生物或化学传感等领域具有良好的应用前景。
