标题:地球储量丰富的多相钴催化剂用于(杂)芳烃的选择性环加氢和医药中间体的克级合成
摘要:开发可以替代贵金属基催化剂的非贵金属基加氢催化剂是非常理想的,但在科学和技术上都具有挑战性.在此,我们提出了一种简便且环保的方法来合成松针生物质衍生的氮掺杂碳负载co 3 O 4纳米粒子(co 3 O 4 /pnc).整个过程包括用硝酸钴盐浸渍松针,然后在氮气气氛下在 500oc 下热解.应用这种 Co 3 O 4 /pnc 纳米催化剂,可产生多种取代酚和功能性有机化学品,包括n-和o-杂芳烃,可以有效地转化为其相应的环氢化产物,产率从非常好到优异(> 55个例子).此外,这种催化方法已被证明可用于制备克级的七种关键药物中间体,这些中间体通常用于批量生产活性药物成分.有利地,环己烷甲酸,吡喹酮的关键药物结构单元,是由聚苯乙烯以两步法合成的.通过高分辨率透射电子显微镜,X 射线光电子能谱,X 射线衍射,N 2彻底研究了新鲜和废 Co 3 O 4 /pnc 纳米催化剂的关键物理化学性质.吸附-解吸,拉曼分析,H

标题 :Synthesis of hierarchical nanocrystalline zeolites with controlled particle size and mesoporosity

权利人:LARSEN SARAH; PETUSHKOV ANTON; UNIV IOWA RES FOUND
摘要:A one step synthesis of nanocrystalline zeolites ZSM-5 and Naβ from a single template system in high yield has been discovered. The size of individual nanocrystals, as well as mesopore surface area and pore volume can be controlled by adjusting the pH of the reaction mixture, as well as the hydrothermal treatment temperature and duration. The mesopore volume and size distribution show a dependence on particle size such that smaller particles lead to higher mesopore volumes and narrower pore size distributions.
