| 1 | Synthesis of a new ordered mesoporous NiMoO_4 complex oxide and its efficient catalytic performance for oxidative dehydrogenation of propane显示文摘Highly ordered mesoporous NiMoO4material was successfully synthesized using mesoporous silica KIT-6 as hard template via vacuum nanocasting method. The structure was characterized by means of XRD, TEM, N2adsorption-desorption, Raman and FT-IR. The mesoporous NiMoO4with the coexistence of α-NiMoO4and β-NiMoO4showed well-ordered mesoporous structure, a bimodal pore size distribution and crystalline framework. The catalytic performance of NiMoO4was investigated for oxidative dehydrogenation of propane. It is demonstrated that the mesoporous NiMoO4catalyst with more surface active oxygen species showed better catalytic performance in oxidative dehydrogenation of propane in comparison with bulk NiMoO4. | Xiaoqiang Fan Jianmei Li Zhen Zhao Yuechang Wei Jian Liu Aijun Duan Guiyuan Jiang | 2014 | Journal of Energy Chemistry2014，23，2： | 6 |
| 2 | Cr掺杂的丙烷选择氧化制丙烯酸高效催化剂显示文摘在丙烷选择氧化制丙烯酸催化剂MoVTeNbOx的活性相M1基础上掺杂一定量的Cr,当Cr/Nb摩尔比为0.002时,催化剂具有很高的丙烯酸选择性(78.3%)和收率(50.7%);并采用X射线衍射、X射线光电子能谱、程序升温还原、O2程序升温脱附、NH3程序升温脱附和异丙醇氧化等手段对催化剂的构效关系进行了探讨.结果表明,适量Cr的添加可调节催化剂表面Mo6+,V5+和Te4+等物种含量,提高催化剂的氧化能力,使丙烷转化率增加.同时,适量Cr的添加使得催化剂表面酸强度下降,酸性位点数量减少,从而抑制丙烯酸的深度氧化,提高了丙烯酸选择性. | 徐爱新 王阳 葛汉青 陈淑 李彦花 陆维敏 | 2013 | 催化学报2013，34，12： | 5 |
| 3 | Effect of Sr loading on oxydehydrogenation of propane to propylene over Al_2O_3-supported V-Mo catalysts显示文摘Incorporation of strontium into V-Mo alumina-supported catalyst enhanced its performance (increased conversion and selectivity,decreased reducibility and improved stability) in propane oxydehydrogenation to propylene.12.5% Sr loading was shown to be the optimum content to the V-Mo catalyst.The results were supported by various characterization techniques,namely,BET,XRD,SEM,FTIR and TPD. | Meilana Dharma Putra Saeed M.Al-Zahrani Ahmed E.Abasaeed | 2013 | Journal of Energy Chemistry2013，22，5： | 2 |
| 4 | 蜂窝陶瓷负载复合氧化物对PAHs的降解研究显示文摘以蜂窝陶瓷为载体,铜锰氧化物为活性组分,CeO_(2)为助剂,通过浸渍法制备CuMnO_(x)-CeO_(2)/CC催化剂,利用氮吸附、X射线衍射、扫描电镜、热重4种手段对催化剂的结构进行表征,并结合固定催化床考察了催化剂对萘、菲、芘3种多环芳烃的催化氧化性能。结果表明:19.1%CuMnO_(x)-CeO_(2)/CC的催化氧化性能最佳,其对萘、菲、芘的催化率分别达到了69%、64%和63%,SEM和XRD结果也显示19.1%CuMnO_(x)-CeO_(2)/CC时活性组分在载体表面的分散达到单层分散阙值,生成了铜锰尖晶石,铜锰尖晶石的存在可以显著的提高催化剂的性能。 | 单龙 徐菲菲 王玲 | 2022 | 绿色科技2022，24，18： | 0 |
