反相微乳液法是一种合成金属纳米颗粒的有效方法，以十六烷基三甲基溴化铵（CTAB）、正戊醇、环己烷、金属盐溶液构建反相微乳液体系，制备了一系列用于合成甲醇的纳米铜基催化剂，并分别对其结构、形貌和活性进行了表征。结果表明，催化剂制备过程中的老化温度、碱浓度、H₂O/CTAB的摩尔比以及盐溶液的浓度对催化剂的粒径和活性均有一定的影响，为甲醇合成催化剂的新型制备方法提供了借鉴。

Reverse microemulsion method is an effective way to prepare metal nanoparticles.In this study,a reverse microemulsion system is set up by using hexadecyl trimethyl ammonium bromide (CTAB),n-pentyl alcohol,cyclohexane and metal salt solutions,and is then used to prepare a series of Cu based catalysts for methanol synthesis.Characterization of structure,morphology and catalytic activity of these catalysts are studied respectively.The results indicate that the aging temperature,alkali concentration and the molar ratio of H₂O/CTAB in preparation process have substantial influences on the particle sizes and activity of the catalysts,which provides a new preparation method of methanol synthesis catalysts.
