将快速凝固的Al77Pd23合金在无腐蚀条件下脱合金化，可制得纳米孔Pd薄带。纳米孔Pd呈现典型的双连续互穿簇沟结构。这些星系团由平行的杆组成，它们之间有很大的通道。棒也是纳米多孔的，并表现出超细的韧带/通道结构。通过测量样品在N_2-H_2气氛下的电阻变化，研究了纳米孔Pd薄带的氢敏特性。纳米多孔Pd条带的响应速度快，检测下限低至0.01vol%。考虑到制备工艺的简单性和良好的灵敏度，目前的纳米孔钯在传感应用方面是很有前途的。
Nanoporous Pd ribbons can be fabricated by dealloying a rapidly solidified Al77Pd23alloy under free corrosion conditions. The nanoporous Pd exhibits a typical bicontinuous interpenetrating cluster–channel structure. The clusters are composed of parallel rods, with large channels between them. The rods are also nanoporous and exhibit an ultrafine ligament/channel structure. Hydrogen sensing properties of the nanoporous Pd ribbons were investigated by measuring the electrical resistance changes of the samples under N2–H2flow. Nanoporous Pd ribbons were found to have a quick response and a detection limit as low as 0.01vol%. Considering the simplicity of fabrication as well as the good sensitivity, the present nanoporous Pd is promising in sensing applications.
