钯纳米颗粒近年来在偶联反应、催化加氢和氧化等反应中被广泛应用,并且被用于储氢材料和燃料电池催化电极等领域。在多相催化领域中,纳米技术能够通过改变金属钯的尺寸和形貌来提高其利用率和催化活性,而制备方法是决定钯纳米颗粒性能的关键。从钯纳米颗粒在催化领域的应用方面对近年来钯纳米催化剂的制备方法进行了综述。 In recent years, palladium nanoparticles have been widely used in coupling reactions, catalytic hydrogenation and oxidation reactions, and have been used in hydrogen storage materials and fuel cell catalytic electrodes. In the field of heterogeneous catalysis, nanotechnology can improve its utilization and catalytic activity by changing the size and morphology of metal palladium, and the preparation method is the key to determine the properties of palladium nanoparticles. In this paper, the preparation methods of palladium nanocatalysts in recent years are reviewed in the field of catalysis of palladium nanoparticles.
