Rod-like ZnO piezoelectric catalytic porous ceramic material and preparation method and application thereof
The invention provides a rod-like ZnO piezoelectric catalytic porous ceramic material and a preparation method and application thereof. The rod-like ZnO piezoelectric catalytic porous ceramic materialcomprises a porous ceramic matrix and a catalytic unit which is attached to the surface and the interior of the matrix and has a piezoelectric effect, wherein the catalytic unit at least comprises rod-like ZnO particles, the diameter of each rod-like ZnO particle is 50-200 nm, and the length of each rod-like ZnO particle is 500-300 [mu]m. The ferrate piezoelectric catalytic porous ceramic material provided by the invention has the piezoelectric effect, can efficiently degrade volatile organic compounds under the action of wind energy, mechanical energy or sound wave energy, can remove toxic and harmful gas through catalytic oxidation while realizing dust removal without extra energy supply when applied to an industrial pulse dust remover, and avoids the emission of secondary greenhouse gas. The material is stable in performance, reusable and low in cost, and the preparation method is simple, feasible, green and environmentally friendly.
本发明提供一种棒状ZnO压电催化多孔陶瓷材料、其制备方法与应用，其包括多孔陶瓷基体以及附着于基体表面及内部的具有压电效应的催化单元，所述催化单元至少包括棒状ZnO颗粒，所述棒状ZnO颗粒的直径为50‑200nm，长度为500nm‑300μm。本发明提供的铁酸盐压电催化多孔陶瓷材料具有压电效应，在风能、机械能或声波能作用下可高效降解挥发性有机物，应用于工业脉冲除尘器中，可实现除尘的同时催化氧化除去有毒有害气体，无需额外提供能量，避免了二次温室气体的排放。且该材料性能稳定、可重复使用，成本低，制备方法简单易行，绿色环保。
