以香樟叶提取物为原料制备了Au/TiO 2催化剂。采用TEM、XRD、DRUV-vis等手段对催化剂进行了表征，并将其用于CO氧化反应。详细研究了各种参数（Au负载量、生物量、焙烧气氛和载体晶型）对CO氧化催化性能的影响。实验结果表明，在Au负载量为1.0 wt %、焙烧气氛为空气、TiO 2为金红石和金红石混晶的条件下，制备的Au/TiO 2催化剂具有最佳的催化性能，150 h后CO转化率仍保持在90%以上。
Au/TiO2 catalysts were synthesized through Cinnamomum camphora leaf extract. The obtained catalysts were characterized through TEM, XRD, DRUV-vis and were used for CO oxidation. The influence of various parameters (Au loading, biomass, calcination atmosphere, and support crystal form) on the catalytic performance in CO oxidation was studied in detail. The experimental result revealed that under the conditions of 1.0 wt % Au loading, calcination atmosphere of air, TiO2 with mixed crystal of rutile and anatase, the Au/TiO2 catalyst exhibited optimum catalyitc performance, which remained its 90% CO conversion after 150 h.
