因此，纳米尺寸和支持退火金属产品仍然是一个挑战。另一个困难是直接制备纳米催化剂，同时获得良好的晶粒尺寸控制。一个好的催化剂载体应该能够抑制反应过程中催化剂的烧结和损失，纳米尺度的负载金属间化合物催化剂的制备需要一种可靠的方法，这种方法不仅有利于尺寸控制，而且在反应条件下具有热稳定相。自从1991年饭岛的工作以来，
Therefore, nanosizing andsupporting the annealed metal products remain challenges.Another difficulty is in directly preparing supportedcatalysts while simultaneously obtaining good crystallite sizecontrol. A good catalyst support should be capable ofinhibiting sintering and loss of the catalyst during reaction.Fabrication of supported intermetallics catalysts in nanoscaledimensionsrequiresareliablemethodthatfacilitatesnotonlysize control but a thermally stable phase under reactionconditions. Since the work of Iijima in 1991,
