采用热水处理方法，由铝钯合金薄膜制备超细纳米多孔钯铝薄膜。使用柠檬酸作为螯合剂，抑制了勃姆石（氢氧化铝，AlOOH）在纳米多孔钯铝薄膜上的沉淀。根据横截面扫描透射电子显微镜观察，所制备的纳米多孔膜的韧带/孔径相当小（大约10 nm）。由于该制备方法仅需要铝合金薄膜和含有螯合剂的热水，因此可以简单且环保地制备超细纳米多孔薄膜。
Hot-water-treatment has been adapted to fabricate ultrafine nanoporous palladium-aluminum film from aluminum-palladium alloy film. Using citric acid as a chelating agent, a precipitation of boehmite (aluminum oxide hydroxide, AlOOH) on the nanoporous palladium-aluminum film was suppressed. According to cross-sectional scanning transmission electron microscopy observations, the ligament/pore sizes of the prepared nanoporous film were considerably small (on the order of 10 nm). Since this fabrication method only requires aluminum alloy film and hot-water with chelating agent, the ultrafine nanoporous film can be prepared simply and environmentally friendly.
