纳米多孔钯粉末是在- 20 ~ 30℃的温度下，通过抗坏血酸在浓缩的水表面活性剂中化学还原四氯络合物，以毫克到克的尺度合成的。通过电子断层扫描，颗粒直径约为50纳米，每个颗粒上有3纳米的孔。这些材料在储存氢同位素和电荷方面具有潜在的价值；以安全和有效的方式大规模生产它们将有助于实现这一目标。一个稍微修改的程序也可以产生纳米多孔铂。(C) 2009年国际氢能协会。Elsevier Ltd.出版。版权所有。
Nanoporous palladium powders are synthesized on milligram to gram scales by chemical reduction of tetrachloro complexes by ascorbate in a concentrated aqueous surfactant at temperatures between - 20 and 30 degrees C. Particle diameters are approximately 50 nm, and each particle is perforated by 3 nm pores, as determined by electron tomography. These materials are of potential value for storage of hydrogen isotopes and electrical charge; producing them at large scales in a safe and efficient manner will help realize this. A slightly modified procedure also results in nanoporous platinum. (C) 2009 International Association for Hydrogen Energy. Published by Elsevier Ltd. All rights reserved.
