style=\"color:red\">钨</span><span style=\"color:red\">酸</span><span style=\"color:red\">铵</span>催化剂(AMT/SiO2)上邻苯二酚和甲醇气相单醚化反应的性能. 结果表明,经533和573 K焙烧的AMT/SiO2催化剂表现出较高的邻苯二酚转化率(97%)和主产物邻羟基苯甲醚的选择性(91%). 程序升温脱附和吡啶吸附红外光谱结果表明,催化剂表面存在的弱酸-弱碱位是反应的活性中心. 经533 K焙烧制备的催化剂在反应最初 46 h 内保持较高的稳定性,随着反应时间延长,邻苯二酚的转化率逐渐降低,但主产物的选择性基本保持不变. 扫描电镜和差热热重分析结果表明,催化剂表面积炭是其活性下降的主要原因,采用适当的焙烧处理可以消除大部分积炭,从而部分恢复催化剂活性.","authors":[{"authorName":"邹秀晶","id":"b1d63f13-ae25-408a-bf42-89ecbc515093","originalAuthorName":"邹秀晶"},{"authorName":"朱小梅","id":"507636fc-272f-4e1c-8a03-b6e6a45b899b","originalAuthorName":"朱小梅"},{"authorName":"李雪梅","id":"debaaf4f-3bd2-48be-8446-c4bd0770123e","originalAuthorName":"李雪梅"},{"authorName":"王振旅","id":"ca07c40f-3959-486f-906e-5fd016063f47","originalAuthorName":"王振旅"},{"authorName":"刘钢","id":"bc45cb74-e753-42aa-9a64-39c75f6470f9","originalAuthorName":"刘钢"},{"authorName":"贾明君","id":"33ad15ab-0fc5-49be-b97f-f177e4e8f6a7","originalAuthorName":"贾明君"},{"authorName":"张文祥","id":"b5ac42c6-7463-4f7e-8dad-199d47940155","originalAuthorName":"张文祥"}],"doi":"","fpage":"671","id":"b23c894d-2bae-47cc-9879-766bccef0d03","issue":"7","journal":{"abbrevTitle":"CHXB","coverImgSrc":"journal/img/cover/CHXB.jpg","id":"18","issnPpub":"0253-9837","publisherId":"CHXB","title":"催化学报
