Nickel-doped KNbO3 piezoelectric ceramic, and preparation method and high-purity hydrogen production application thereof
The invention provides a nickel-doped KNbO3 piezoelectric ceramic, and a preparation method and high-purity hydrogen production application thereof. The ceramic material comprises a KNbO3 piezoelectric ceramic matrix and Ni atoms uniformly distributed in the KNbO3 piezoelectric ceramic matrix, the mass fraction of the Ni atoms is 1 wt%-10 wt%, and the pore diameter of the KNbO3 piezoelectric ceramic matrix is 0.1 nm to 1.0 nm. The nickel-doped KNbO3 piezoelectric ceramic material provided by the invention has relatively high catalytic activity, the use of noble metals is reduced, so that the production cost is greatly reduced, the preparation method is simple and easy to implement, green and environment-friendly, no substances harmful to the environment are discharged, the nickel-doped KNbO3 piezoelectric ceramic material provides high-purity hydrogen as a hydrogen fuel cell, and the high-purity hydrogen does not contain carbon monoxide, hydrogen sulfide, hydrogen phosphide, chloride ions and other gases causing poisoning of the fuel cell.
本发明提供一种镍掺杂KNbO3压电陶瓷、其制法及高纯制氢。该陶瓷材料包括KNbO3压电陶瓷基体以及均匀分布于KNbO3压电陶瓷基体中的Ni原子，所述Ni原子的质量分数为1wt％～10wt，所述KNbO3压电陶瓷基体的孔径为0.1nm～1.0nm。本发明提供的一种镍掺杂KNbO3压电陶瓷材料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，且制备方法简单易行、绿色环保，不排放对环境有害物质，作为氢燃料电池提供高纯氢，不含有一氧化碳、硫化氢、磷化氢、氯离子等使燃料电池中毒的气体。
