Pt monatomic strontium zirconate piezoelectric porous ceramic and preparation method thereof and high-efficiency hydrogen production
The invention provides a Pt monatomic strontium zirconate piezoelectric porous ceramic and a preparation method thereof and an application of the Pt monatomic strontium zirconate piezoelectric porous ceramic in self-energized high-efficiency hydrogen production. The piezoelectric porous ceramic comprises a SrZrO3 piezoelectric porous ceramic matrix and Pt single atoms uniformly dispersed on the surface and in pore channels of the piezoelectric porous ceramic matrix, and the mass fraction of the Pt single atoms is 0.01 wt%-0.1 wt%. The Pt monatomic SrZrO3 piezoelectric porous ceramic material provided by the invention is low in Pt content and relatively high in catalytic activity, and the use of noble metals is reduced, so that the production cost is greatly reduced. The Pt monatomic SrZrO3 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 gases such as carbon monoxide, hydrogen sulfide, hydrogen phosphide and chloride ions which can poisoning the fuel cell, and the preparation method is simple, easy to implement, green, environmentally friendly and free of emission of substances harmful to the environment.
本发明提供一种Pt单原子锆酸锶压电多孔陶瓷、其制法与自供能高效制氢中的应用。该压电多孔陶瓷包括SrZrO3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Pt单原子，所述Pt单原子的质量分数为0.01wt％‑0.1wt％。本发明提供的一种Pt单原子SrZrO3压电多孔陶瓷材料中Pt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Pt单原子SrZrO3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。
