The preparation process includes the following steps: mixing 10 mM concentration water solution of chloropalladic acid and 12.5-25 mM concentration water solution of ammonium hexadecyl trimethyl bride in the volume ratio of 1 to 20, heating to 65-95 deg.c, adding 100 mM concentration water solution of ascorbic acid in the volume ratio to the water solution of chloropalladic acid of 0.16 to 1 to react for 30 min, centrifugal separation to collect precipitate, water washing, and drying to obtain cuboidal nanometer Pd material.

该钯纳米长方体材料的制备方法的步骤和条件法如下：把体积比为1∶20的10mM氯钯酸水溶液和12.5-25mM十六烷基三甲基溴化铵水溶液混合，加热至65-95℃，然后加入与10mM氯钯酸水溶液的体积比为0.16∶1的100mM抗坏血酸水溶液，反应30分钟，将溶液离心分离，收集到的沉淀用水洗涤，干燥，得到钯纳米长方体。
