General description
四氯钯酸钾(II)是一种深棕色结晶固体,广泛用作催化、纳米材料合成和电子领域的钯源。
Application
四氯钯酸钾(II)可用于:
- 作为前体 合成用于催化降解有机污染物的Pd纳米颗粒, 以及用于甲酸和乙醇氧化的Pd-GO电催化剂。
- 以均匀的Pd八面体纳米晶和立方纳米晶(NC)为牺牲模板,采用电偶置换法合成具有空心结构的Pd–Pt 合金 NC。中空NC的ORR活性更高。
- 合成 固定化Pd催化剂,这种通用方法是 将PAA和PEI-Pd(II)逐层沉积在氧化铝上,然后还原 Pd2+。这种方法有几个好处, 包括通过聚电解质基质稳定颗粒、引入选择性 以及显著减少不必要的异构化。扩大聚电解质薄膜的应用有望进一步提高 加氢反应和 其他反应的选择性。
- 制备用于气敏应用的导电性多孔金属有机骨架(MOF), 还可在金属有机骨架(MOF)上 合成双金属 Pd/SnO2纳米颗粒,作为乙醇氧化的 电催化剂。
- 制备具有多芳烃配体 的刚性大环钳形催化剂,催化 活性更强。
Features and Benefits
用于合成半导电的含金属聚合物,在聚合物中聚吡咯主链具有最低的构象能,并且几乎成平面。与双二硫醇盐反应生成金属-双二硫醇盐,可用于激光器 Q 开关材料、光盘记录介质、条形码材料和超导体。

In the last decades, palladium is widely used in dentistry. Allergic reactions to palladium are rarely diagnosed with patch testing, even when positive results would be expected. Palladium tends to cross-react with nickel, which should give rise to more positive
