Diazaspiro [ 4. 4 ] nonane was synthesized from malononitrile as the starting material by a series of nucleleophilic displacement, hydrolytic cyclization and carbonyl reduction
摘要以丙二腈為原料，經過親核取代、水解環合、羰基還原系列反應，合成了2 ， 7 -二氮螺[ 4 . 4 ]壬烷。 -
Some methods for synthesizing magnetic cobalt nanoparticles are introduced, especially the high temperature liquid phase method including the method of high temperature solution phase reduction, metal salt diol reduction and pyrolysis of cobalt carbonyl is elucidated in this paper. meanwhile, the mechanism controlled the nanoparticles dimension by the two kinds of surfactants is explained theoretically
摘要介紹了制備磁性鈷納米粒子的方法，尤其是介紹了近年發展起來的高溫液相法，即高溫液相還原法，金屬鹽醇解法和金屬有機化合物熱分解法；同時就制備顆粒尺寸小、粒度分佈均勻的鈷納米粒子所採用的兩種表面活性劑從理論上給予了說明。 -
Nevertheless, the step toward the practical application has not been developed as fast as had been expected. mainly, there are some problems, such as low electrocatalytic activity of the anodic catalyst, the poisoning of the anode catalysts by the adsorbed carbonyl species derived from methanol oxidation, methanol permeation from anode to cathode and demand for methanol - tolerant oxygen reduction catalyst
然而，陽極催化劑的低催化活性、甲醇氧化中間體羰基物對陽極催化劑的毒化、甲醇從陽極向陰極的滲透、以及由甲醇滲透引起的陰極氧還原抗甲醇要求等，致使dmfc的實際應用發展速度一直沒有預期的快。
