초록
Al-Cu alloy nano powders have been produced by the electrical explosion of Cu-plated Al wire.The porous nano particles were prepared by leaching for Al-Cu alloy nano powders in 40 wt% NaOH aqueoussolution. The surface area of leached powder for 5 hours was 4 times larger than that of original alloy nano pow-der. It is demonstrated that porous nano particles could be obtained by selective leaching of alloy nano powder. Itis expected that porous Cu nano powders can be applied for catalyst of SRM (steam reforming methanol).
