Piezoelectric catalytic porous ceramic material and preparation method and application thereof
The invention provides a piezoelectric catalytic porous ceramic material and a preparation method and application thereof. The material comprises a porous ceramic matrix and a catalytic unit which isattached to the surface and the interior of the matrix and has a piezoelectric effect, wherein the catalytic unit at least comprises titanate, and a titanate material comprises titanium ions and positive divalent cations in a molar mass ratio of 1: 1. The piezoelectric catalytic porous ceramic material provided by the invention has a piezoelectric effect, can efficiently degrade volatile organic compounds under the action of wind energy, mechanical energy or sound wave energy, does not need to additionally provide energy, and avoids emission of secondary greenhouse gas. The piezoelectric catalytic porous ceramic material is stable in performance, reusable and low in cost, and the preparation method is simple, feasible and environmentally-friendly. The piezoelectric catalytic porous ceramicmaterial is applied to an industrial dust remover, and can remove toxic and harmful gas while removing dust; and when applied to an air purifier and an air conditioner, the piezoelectric catalytic porous ceramic material overcomes the problem that a photocatalyst needs to be driven by a light source and the problem that activated carbon needs to be frequently replaced after adsorption is saturated.
本发明提供一种压电催化多孔陶瓷材料、其制备方法与应用。该材料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钛酸盐，所述钛酸盐材料包括钛离子和正二价阳离子，所述钛离子与正二价阳离子的摩尔质量比为1:1。本发明提供的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，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。该压电催化多孔陶瓷材料应用于工业除尘器中，在除尘的同时可以除去有毒有害气体；应用于空气净化器和空调中，克服了光催化剂需要光源驱动的问题，也克服了活性炭吸附达到饱和后需要频繁更换的问题。
