Ceramic rock plate and preparation method thereof
The invention discloses a ceramic rock plate and a preparation method thereof, and belongs to the field of building materials.Titanium dioxide, zinc oxide and zinc zirconate are mixed, and during photocatalysis, titanium dioxide migrates and has a synergistic effect with zinc oxide and zinc zirconate, so that the recombination rate of electron-hole pairs is effectively reduced; meanwhile, a silane coupling agent is added for modification, so that crystal lattices form defects, photo-induced electron-hole capturing hydrazine is formed, the recombination rate of electron-hole pairs can be further reduced, the existence time of electrons and holes is prolonged, the catalytic performance is enhanced, valence band bandwidth is shifted upwards, forbidden band bandwidth is correspondingly reduced, and the catalytic performance is improved. On the whole, not only can a remarkable effect of catalytically degrading formaldehyde be achieved, but also a remarkable antibacterial effect is achieved, so that a higher application value is achieved.
本发明公开了一种陶瓷岩板及其制备方法，属于建筑材料领域，本发明通过将二氧化钛、氧化锌以及锆酸锌混合，当光催化时，二氧化钛发生迁移，与氧化锌以及锆酸锌协同作用，有效减少电子‑空穴对的复合速率；同时添加了硅烷偶联剂改性，使得晶格形成缺陷，形成光生电子‑空穴捕获肼，不仅能进一步减少电子‑空穴对的复合速率，增加电子与空穴的存在时间，达到增强催化性能，还使得价带宽化上移，禁带宽带相应减小，整体上不仅能起到显著的催化降解甲醛的效果，还起到显著的抗菌作用，使得具有更高的应用价值。
