非通孔多孔氧化铝基底上原位生成Pd纳米材料的制备及应用
Preparation and Application of Pd Nanomaterials Grown in situ on Non-Through-Hole Porous Alumina
摘要
Abstract
Using non-through-hole anodic aluminum oxide(AAO) as templates, with Al substrate as support body, Pd nanomaterials were prepared in situ in the channels of AAO with Al substrate as reducing agent.The removal of barrier layer and acid corrosion post-treatment of synthesized Pd/AAO were studied.The Pd morphologies under different situations were observed by scanning electronic microscopy.A plausible mechanism of Pd formation was proposed.The catalytic activity for Suzuki reaction of 4-bromobenzene carboxylic acid and phenylboronic acid was investigated with Pd/AAO as heterogeneous catalysts.It is found that Pd/AAO catalysts exhibit excellent catalytic activity, and the yield is up to 99.8% with 0.06% molar fraction of Pd.The catalysts with sheet structure are easily separated for recovery by just taking out of the solution and can be reused in the next time.This research gives a practical method for the design of heterogeneous catalysts in organic reactions.关键词
