摘　　要：从Pd—C催化剂废料回收Pd（N03）2，然后在SDS／Brij30／H20体系O／W微乳液中制备纳米钯。结果表明：制备的钯纳米粒子的粒度在5-200nm之间：使用该体系不需外加还原剂，可直接利用非离子表面活性剂Brij30作为还原剂，简化后续单元操作。并初步探讨了SDS／Brij30／H2O体系O／W微乳液中纳米钯的制备机制。A new technic preparing nanopalladium from waste Pd-C catalyst was introduced in the present study. At first, Pd（NO3）2 was recycled from the waste Pd-C catalyst, then, the palladium nanoparticles with size of 5 nm to 200 nm were generated in the O/W microemulsion of sodium dodecyl sulfate （SDS）, Brij30 and H20 system by using nonionic surfactant Brij30 as the reducing agent. The preparation mechanism of nanopalladium in the O/W microemulsion of SDS/Brij30/H2O system was also discussed.
