Pd monatomic potassium niobate piezoelectric porous ceramic and preparation method thereof and efficient hydrogen production
The invention provides Pd monatomic potassium niobate piezoelectric porous ceramic and a preparation method thereof and an application of the Pd monatomic potassium niobate piezoelectric porous ceramic in self-energized efficient hydrogen production. The piezoelectric porous ceramic comprises a KNbO3 piezoelectric porous ceramic matrix and Pd single atoms uniformly dispersed on the surface and in pore channels of the piezoelectric porous ceramic matrix, and the mass fraction of the Pd single atoms is 0.01 wt%-0.1 wt%. The Pd monatomic KNbO3 piezoelectric porous ceramic material provided by the invention is low in Pd content and has relatively high catalytic activity, and the use of noble metals is reduced, so that the production cost is greatly reduced. The Pd monatomic KNbO3 piezoelectric porous ceramic material can be used for providing a hydrogen source for a hydrogen fuel cell, is high in hydrogen production efficiency and purity, and does not contain carbon monoxide, hydrogen sulfide, hydrogen phosphide, chloride ions and other gases capable of poisoning the fuel cell, and the preparation method is simple and easy to implement, green and environment-friendly, and does not discharge substances harmful to the environment.
本发明提供一种Pd单原子铌酸钾压电多孔陶瓷、其制法与自供能高效制氢中的应用。该压电多孔陶瓷包括KNbO3压电多孔陶瓷基体以及均匀分散于压电多孔陶瓷基体表面及孔道内的Pd单原子，所述Pd单原子的质量分数为0.01wt％‑0.1wt％。本发明提供的一种Pd单原子KNbO3压电多孔陶瓷材料中Pd的含量低，同时具有较高的催化活性，降低了贵金属的使用，从而大大降低了生产成本。该Pd单原子KNbO3压电多孔陶瓷材料可用为氢燃料电池提供氢源，制氢效率高、纯度高，不含一氧化碳、硫化氢、磷化氢、氯离子等使燃料电池中毒的气体，且制备方法简单易行、绿色环保，不排放对环境有害物质。
