Nanoporous metallic glass with high surface area

摘要

The synthesis of uniformly distributed nanoscale pores within a Cu_(47)Ti_(33)Zr_(11)Ni_8Si] metallic glass is described. The porous metallic glass was obtained by extruding layered Cu-based metallic glass + Cu composite powders followed dissolution of the Cu in a HNO_3 solution. The porous metallic glass has a specific surface area of 23.5 m~2/g.
