Bismuth-based ferroelectric or piezoelectric ceramic material with photocatalytic memory effect, preparation method of bismuth-based ferroelectric or piezoelectric ceramic material and application of bismuth-based ferroelectric or piezoelectric ceramic material in field of regulation and control of catalysis
The invention discloses a bismuth-based ferroelectric or piezoelectric ceramic material with a photocatalytic memory effect as well as a preparation method and application of the bismuth-based ferroelectric or piezoelectric ceramic material in the field of regulation and control of catalysis, and belongs to the technical fields of preparation of inorganic nonmetal ceramic materials, solar energy utilization and environmental protection. The ceramic material is prepared by a solid-phase sintering method. The synthesized ceramic can generate obvious color change under visible light irradiation and has an obvious photocatalytic memory effect, and the ceramic powder with the memory effect can effectively improve the efficiency of degrading antibiotics in a water body through photocatalysis, piezoelectric catalysis and light-pressure synergistic catalysis. Not only is the application field of the ceramic material widened, but also the degradation efficiency is improved through the photocatalytic memory effect, and a more efficient material is provided for effectively solving water body pollution.
本发明公开了一种具备光催化记忆效应的铋系铁电或压电陶瓷材料及其制备方法和在调控催化领域中的应用，属于无机非金属陶瓷材料制备、太阳能利用与环境保护技术领域。该陶瓷材料是由固相烧结法制备而成。所合成的陶瓷在可见光辐照下可发生明显的颜色变化，具有明显的光催化记忆效应，并且发生记忆效应的陶瓷粉体可以有效提高光催化，压电催化及光‑压协同催化降解水体中抗生素的效率。不仅扩宽了陶瓷材料的应用领域，还通过光催化记忆效应提高了降解效率，为有效的解决水体污染提供了一种更高效的材料。
