| 摘 要：以木質(zhì)素降解產(chǎn)物香草醇替代苯酚，合成中加入金前驅體和穩定劑，在模板劑F127（EO106PO70EO106）存在下，一步法合成了具有蠕蟲(chóng)狀孔道結構的納米金/香草醇基介孔碳催化劑。催化劑催化氧化苯甲醇性能良好。優(yōu)化條件為：催化劑用量25 mg，苯甲醇1 mmol，碳酸鉀用量2 mmol，水用量5 mL，反應溫度100 ℃，反應時(shí)間6 h。優(yōu)化條件下，苯甲醇轉化率為98.4%，苯甲酸選擇性為98.0%。催化劑重復使用4次，其催化性能基本保持不變。 |

| Abstract：Using vanillyl alcohol, being one of degradation products of lignin, as a substitution for phenol, Au nanoparticle/mesoporous carbon composite catalysts with worm-like mesostrucsture were prepared via an one-pot procedure involving in-situ addition of Au precursor and stabilizer in the presence of template of F127 (EO106PO70EO106). The resultant catalysts showed good catalytic performance in aerobic oxidation of benzyl alcohol. Under optimal reaction conditions (25 mg of catalyst, 1 mmol of benzyl alcohol, 2 mmol of K2CO3, 5 mL of water, 100 ℃, 6 h), the conversion of benzyl alcohol and the selectivity to benzoic acid were as high as 98.4% and 98.0%, respectively. In addition, the above catalyst could be used for 4 times without significant loss of catalytic activity. |
