Nitrogen-doped carbon materials encapsulating 3 d transition metals are promising alternatives to replace noble metal Pt catalysts for efficiently catalyzing the oxygen reduction reaction(ORR). Herein, we use cobalt substituted perfluorosulfonic acid/polytetrafluoroethylene copolymer and dicyandiamide as the pyrolysis precursor to synthesize nitrogen-doped carbon nanotube(N–CNT) encapsulating cobalt nanoparticles hybrid material. The carbon layers and specific surface area of N–CNT have a critical role to the ORR performance due to the exposed active sites, determined by the mass ratio of the two precursors. The optimum hybrid material exhibits high ORR activity and stability, as well as excellent performance and durability in zinc–air battery.

Chemical modification(CM)and deposition-precipitation(DP)methods were used for the dispersion of active Au nanoparticles on mesoporous silica materials in this ***,TEM,N2 adsorption isotherms and UV-Vis absorption spectra were used to characterize in detail Au-SBA-15 materials prepared by the two methods. The analysis results showed that high loading(1.7%,by mass)and uniform Au nanoparticles(approximately 3 nm) were dispersed in the channels of mesoporous SBA-15 by the CM *** for the DP method,most of Au nanoparticles with the size of 10—15nm were aggregated outside of the channels of SBA-15 and the actual loading of Au was only 0.38%(by mass).

采用浸渍法制备了介孔氧化铝(m-Al2O3)负载钒催化剂(V/m-Al2O3),并考察了其催化丙烷氧化脱氢制丙烯反应活性.通过N2吸附-脱附、透射电镜、X射线粉末衍射、紫外-可见漫反射光谱、氢-程序升温还原和氨-程序升温脱附对催化剂进行了表征.结果表明,介孔氧化铝具有大比表面积、窄孔径分布和两维六方相结构,在其上负载适量的V可实现V活性物种的高分散及催化剂的弱酸性,从而有利于提高丙烷转化率和丙烯选择性.与共合成法制备的含V介孔氧化铝V/m-Al2O3(C)和浸渍法制备的V/γ-Al2O3相比,V/m-Al2O3表现出更高的催化活性.这与载体较弱的酸性和较大的比表面积以及V物种的高分散有关.

合成了原位W掺杂的多级孔SiO_(2)纳米球材料(W-HPSN),系统考察了W-HPSN合成过程中短链醇类共溶剂(甲醇、乙醇、正丙醇)的加入对Pt/W-HPSN催化剂甘油氢解制1,3-丙二醇(1,3-PDO)性能的影响.与仅以水为溶剂合成的材料制备的Pt/W-HPSN-H2O催化剂相比,加入醇类共溶剂后,催化剂的比表面积均有不同程度的增大,并在除1.4 nm的微孔和>2 nm的介孔以外,在1.7 nm处出现了新的微孔结构.在甘油氢解反应中,加入醇类共溶剂合成的材料制备的催化剂的催化性能也更高.在最佳的以甲醇作为共溶剂合成的Pt/W-HPSN-Me催化剂上,甘油转化率和1,3-PDO选择性分别为88.8%和56.3%,而Pt/W-HPSN-H_(2)O催化剂上二者分别为64.1%和40.7%.根据表征结果,推测更小的Pt粒径、更多原位产生的Brønsted酸位,有利于提高Pt/W-HPSN催化剂的催化性能.通过对W-HPSN-Me的组成进行优化,发现当W/Si物质的量比为1/320时,Pt/W-HPSN-Me催化剂在423 K、氢气压力4 MPa、反应时间仅为12 h的反应条件下,甘油转化率和1,3-PDO选择性进一步提高至98.7%和58.8%,1,3-PDO得率可达58.0%,展示了HPSN材料作为甘油选择氢解制1,3-PDO催化剂载体的良好应用前景.

Neutrophils play an essential role in the innate immune response to infection. Neutrophils migrate from the vasculature into the tissue in response to infection. Recently, a neutrophil cell surface receptor, CD177, was shown to help mediate neutrophil migration across the endothelium through interactions with PECAMI. We examined a publicly available gene array dataset of CD177 expression from human neutrophils following pulmonary endotoxin instillation. Among all 22,214 genes examined, CD177 mRNA was the most upregu- lated following endotoxin exposure. The high level of CD177 expression is also maintained in airspace neu- trophils, suggesting a potential involvement of CD177 in neutrophil infiltration under infectious diseases. To determine the role of CD177 in neutrophils in vivo, we constructed a CD177-genetic knockout mouse model. The mice with homozygous deletion of CD177 have no discernible phenotype and no significant change in immune cells, other than decreased neutrophil counts in peripheral blood. We examined the role of CD177 in neutrophil accumulation using a skin infection model with Staphylococcus aureus. CD177 deletion reducedneutrophil counts in inflammatory skin caused by S. aureus. Mechanistically we found that CD177 deletion in mouse neutrophils has no significant impact in CXCLI/ KC- or fMLP-induced migration, but led to significant cell death. Herein we established a novel genetic mouse model to study the role of CD177 and found that CD177 plays an important role in neutrophils.
