In this study, a Pt loaded active carbon fiber (Pt/ACF) catalyst was prepared by immobilizing Pt nanoparticles on ACF. The catalyst accelerated hydrogenation of -chloronitrobenzene (-CNB) to -chloroaniline (-CA) at lower temperature and atmospheric pressure, resulting in approximately 100% yield and selectivity. Several factors that affect -CA yield were investigated. The nitro reduction rate reached 100% under the optimal reaction conditions, indicating excellent selectivity of the prepared catalyst. This process will overcome the environmental pollution problems associated with the traditional process, and is a green synthetic process.
在这项研究中，通过将 Pt 纳米颗粒固定在 ACF 上，制备了负载 Pt 的活性碳纤维（Pt/ACF）催化剂。该催化剂在较低温度和常压下加速了 -氯硝基苯（-CNB）向 -氯苯胺（-CA）的加氢反应，产率和选择性约为 100%。考察了影响 -CA 产率的几个因素。在最佳反应条件下，硝基还原率达到 100%，表明所制备的催化剂具有优异的选择性。该工艺将克服传统工艺带来的环境污染问题，是一种绿色合成工艺。
