1机械化学法制备的Al/Ce复合氧化物负载NiMo催化剂的加氢脱硫活性(英文)显示文摘将Al和/或Ce的硝酸盐与NH_4HCO_3球磨混合,采用机械化学法制备了Al_2O_3-CeO_2载体(其中Ce含量为1-10 wt%),再以杂多钼酸盐(NH_4)_4NiMo_6O_(24)为活性金属Ni和Mo的前驱体,通过浸渍法制备NiMo_6/Al_2O_3-CeO_2催化剂,并将其用于1-苯并噻吩(BT)的加氢脱硫(HDS)反应中.运用化学分析、X射线衍射、N_2吸附-脱附法、H_2程序升温还原、NH_3程序升温脱附和X射线光电子能谱对催化剂的物化性质进行了表征.结果表明,催化剂的酸性随着载体中Ce含量的增加而下降.Ce修饰的Al_2O_3载体表面的NiS/MoS原子比下降了2倍.NiMo_6/Al_2O_3催化剂表现出最高的HDS活性(以单位重量催化剂计),其酸性和表面MoO_xS_y物种的浓度(Mo^(5+)浓度)也最高;当催化剂中Ce含量逐渐增加到10 wt%以上时,其活性逐渐将为0.与浸渍法制得的参比催化剂相比,前驱体和催化剂组成相同的情况下,采用机械化学法制得的所有催化剂活性明显提高.Květa Jirátová Alla Spojakina Luděk Kaluza Radostina Palcheva Jana Balabánová Georgi Tyuliev 2016Chinese Journal of Catalysis2016,37,2:6
2Development of oligonucleotide probes for FISH karyotyping in Haynaldia villosa,a wild relative of common wheat显示文摘Haynaldia villosa is a wild relative of wheat and a valuable gene resource for wheat improvement.Owing to the limited number of probes available for fluorescence in situ hybridization(FISH),the resolution at which the karyotype of H.villosa can be characterized is poor,hampering accurate characterization of small segmental alien introgressions.We designed ten oligonucleotide probes using tandem repeats in DNA sequences derived from the short arm of H.villosa chromosome 6 V(6 VS).FISH with seven of them resulted in clear signals on H.villosa chromosomes.Using these,we constructed FISH karyotypes for H.villosa using oligo-6 VS-1 and oligo-6 VS-35 oligonucleotides and characterized the distribution of the two probes in five different H.villosa accessions.The new FISH probes can efficiently characterize H.villosa introgressions into wheat.Jia Lei Jiawen Zhou Haojie Sun Wentao Wan Jin Xiao Chunxia Yuan Miroslava Karafiátová Jaroslav Dolezel Haiyan Wang Xiue Wang 2020The Crop Journal2020,8,4:3
