本文采用一种新型制备工艺在镀铝版基上涂布超疏水超亲水涂层。制备工艺可分为5部分:①在版基上涂布TiO_2涂层;②采用自组装膜进行表面改性;③采用喷墨技术喷印水性抗uv油墨图文;④自组装膜经光催化分解使涂层表面具有超亲水态;⑤用水清除水性油墨图文。值得注意的是,该工艺无须使用光掩膜即可快速形成具有润湿性的图文印版。制备的超疏水-超亲水印版适用于胶印。

以硝酸银为原料,无水乙醇为溶剂,硅溶胶为络合剂,通过溶胶凝胶法获得前驱体,将前驱体置于管式炉中煅烧,制备出Ag_(10)Si_4O_(13)光催化剂。以硅溶胶/硅酸钾溶液与氟碳乳液为基料制备Ag_(10)Si_4O_(13)光催化涂料。通过XRD、SEM、uv-Vis DRS等手段对催化剂进行了表征,并测试了涂料的性能及涂料去除NO的效果。结果表明:Ag_(10)Si_4O_(13)呈柱状结构;光吸收边为640 nm,对应禁带宽度2.02 e V。光催化测试结果表明,在氙灯照射90 min时,Ag_(10)Si_4O_(13)掺量为涂料质量的1.0%时对NO的去除率为68.8%。

Enantioselective formation of C-C bonds is an area of intense research. Among them, the asymmetric addition of alkynyl reagents to aldehydes is very useful for the synthesis of chiral secondary propargyl alcohols, which are very important building blocks for many chiral organic compounds, and the acetylene and hydroxyl founctional group of propargyl alcohol can be easily transfered into many other structures.1Recently, many significant chiral ligands have been disclosed.2 Here, we report our research results in the asymmetric addition of phenylacetylene to *** chose L-phenylalanine and camphor as starting materials, after simple steps, we got 1 and *** 1 and 2 behave excellent catalytic activity for the reaction of enantioselective addition of phenylacetylene to aldehydes (the ee up to 98%) under very mild conditions.3,4L-Proline and its derivatives have become a series of important molecules in asymmetric catalysis due to its rigid structure, easy availability, and cheapness. We used commercial Boc-L-proline as chiral ligand in this reaction and get good result (up to 77% ee).5
