小妹做了制备的催化剂的H2-TPR图,分别在低温和高温处得到一个还原峰。加入某助剂后,两峰同时向低温方向移动,同时随着助剂量的增加,两峰继续向低温处移动,且实际耗氢量增加,这能否说明该助剂的添加使得催化剂更容易还原呢?
某期刊审稿人给的意见是:The authors claim that the shift in peak at ~ 480 K indicated change in reducibility. Not true. The shift in peak with increasing coverage is expected if reaction order is > 1, which should be the case of oxide reduction with increasing oxide loading.
小妹看了一些相关的文献,也都是简单地说了改善了还原性能。想请教一下各位前辈,这个问题怎么回答呀
