金属-配体协同活化的CO2与吡啶基钌PNP钳形催化剂导致显着抑制的活性在催化CO2加氢到甲酸。水的加入通过激活替代反应途径恢复催化性能，并导致前所未有的Ru催化的CO2加氢活性。的基础上提出的DFT计算，动力学实验，和NMR反应性研究的基础上的化学转化的机制。
The metal-ligand cooperative activation of CO2 with pyridine-based ruthenium PNP pincer catalysts leads to pronounced inhibition of the activity in the catalytic CO2 hydrogenation to formic acid. The addition of water restores catalytic performance by activating alternative reaction pathways and leads to unprecedented Ru-catalyzed CO2 hydrogenation activity. The mechanism of the underlying chemical transformations is proposed on the basis of DFT calculations, kinetic experiments, and NMR reactivity studies.
