Nine protic carboxyl imidazolium ionic liquids are synthesized.Then,they are employed to catalyze the chemical fixation of carbon dioxide(CO2)and propylene oxide leading to propylene carbonate in the
The tunable porosity and functional metal sites imparting MOFs with favorable capability for CO2 adsorbing and efficient catalysis centers might create catalytic environments suitable for CO2RR.
Carbon dioxide is an ideal C1 resource,1 because it is abundant,renewable and non-toxic.However,it is thermodynamically stable,which greatly limits its application.
二氧化碳是人体代谢的产物,人每天要呼出大约1 kg 的二氧化碳,当人体血液中或大气中二氧化碳含量超过一定浓度,会引发一系列不良反应.当二氧化碳浓度在0.10-0.20%之间时,人会感觉空气污浊,并开始觉得昏昏欲睡;达到0.2-0.5%时,人会感觉头痛、嗜睡、注意力无法集中;二氧化碳含量达到0.5%以上时,可能会导致严重缺氧,造成永久性脑损伤、昏迷,甚至死亡.
