9°, respectively. Upon loading onto TiO2 nanoparticles (P25), this Ru(II) complex exhibits an efficient CO2 photoreduction ability with CO/CH4 production activities of 26.6/17.2 μmol g−1 h−1 in a gaseous photocatalytic system containing CO2 and H2O vapor, which is much better than that of the pristine TiO2 nanoparticles. This result gives a good example of TiO2 nanoparticles loaded with the Ru(II)
一种新的刚性中性的Ru(II)络合物钳形的[Ru(N'NN')(ONO)]选自阳离子合成的[Ru(N'NN')(MeCN中)2 CL]氯(N'NN',2,6- -双(N-苄基-苯并咪唑-2-基)吡啶)和4,8-二羟基喹啉-2-羧酸(ONO)。X射线衍射分析表明,Ru(II)中心采用略微扭曲的八面体几何形状,其中N'NN'配体的两个苄基部分位于配位平面的同一侧,由三个N原子定义N'NN'和Ru(II)中心的角度,苄基和Ru(II)–N'NN'平面的二面角分别为89.1°和74.9°。在加载到TiO 2纳米颗粒(P25)上时,该Ru(II)配合物在含有CO 2和H 2 O蒸气的气态光催化体系中具有26.6 / 17.2μmolg -1 h -1的有效CO 2光还原能力,CO / CH 4生产活性为26.6 / 17.2μmolg -1 h -1。原始的TiO 2纳米颗粒。该结果给出了负载Ru(II)钳形配合物的TiO
