Studies on the Synthesis of Palladium Hydride Nanocrystals and their Catalytic Properties

Abstract

贵金属纳米材料因其独特的性质和优异的催化性能而备受关注,但其储量有限,迫切需要提高利用效率。作为一种重要的化工材料,贵金属Pd在催化和燃料电池等方面应用十分广泛,如何提高其催化活性和稳定性以及Pd的使用效率具有非常重要的意义。另一方面,虽然现在对Pd基纳米晶的研究较多,但由于Pd与其他过渡金属间原子半径、标准还原电势相差较大,如何形成合金、合金组分的调控还很困难。本文以PdHx、PdCu合金等Pd基纳米晶为研究对象,致力于对其表面结构和组成的调控及构效关系研究。主要内容和研究成果概括如下: 1、 Pd可以形成独特的钯氢化合物而受到广泛关注。我们通过对商业钯黑进行简单的丁胺溶剂热处理,可以得到...The unique character and excellent catalytic properties of a noble metal nano-materials have received much attention, yet their limited reserves greatly impede their applications. As an important material, noble metal Pd is widely applied to catalytic reaction and fuel cell production. It is of great significance to improve its catalytic activity, stability and use efficiency.
