Our laboratory used to synthesize highly crystalline silver micro-dendrites(SMDs)whose surface is very clean with no surfactants on it.As it is very easy to modify different molecules on the surface according to various needs,we used it with confocal laser scanning microscope to detect DNA [1,2].

随着石油资源的短缺和世界各国对油品硫含量的限制,加氢脱硫成为环境催化研究的一个重大课题,其核心是研究和开发新型高效深度加氢脱硫催化剂.前期我们通过理论计算与实验相结合发现硅化镍中Ni-Si 相互作用导致Ni 原子d 态费米能级发生偏移,并且Si 掺入Ni 的晶格中导致Ni-Ni 之间的间距发生变化,从而调变了其加氢脱硫活性,并表现出显著的抗硫性能.
丙烷脱氢制丙烯工艺具有重要应用前景,通过将天然气中的丙烷直接无氧脱氢制取丙烯,有利于减少温室气体排放和提高能源利用效率.纯硅载体本身为化学性质稳定的材料,对其改性可以提高其催化活性[1],本文采用后合成法制备了具有多级孔道结构的SAPO34-mSiO2复合分子筛,具有适宜的酸性和较高的比表面积,并且其多级孔结构有利于催化反应中反应物及产物分子的扩散.
本文采用等体积浸渍法制备了氟改性纳米HZSM-5 分子筛，考察了不同氟含量改性的纳米HZSM-5 催化生物乙醇制丙烯的催化性能.结果表明，当氟含量为20％时，催化性能最好.丙烯选择性由原来的20.2％提高至24.9％，催化剂寿命则由原来的37 h 显著延长至204 h.
We developed a novel polar hyper-cross-linked resin PVDM-P-A with high Brunauer-Emmett-Teller(BET)surface area and moderare functional groups.
丙烯是最重要的有机化工原料,主要来源于蒸汽裂解联产和催化裂化副产.随着石油资源短缺问题日益严重,其产量远不能满足人们的需求.丙烷在我国有相当丰富的储量,因此,将储量丰富的丙烷催化加工成化工中间体或化工原料,有着极大的经济价值和社会意义.由丙烷催化脱氢制取丙烯已经成为了增产丙烯的重要手段.
