一系列的四个Ir和Ru催化剂已经在还原CO2甲酸在H2的存在下进行了测试。含有碱性NHC配体的铱催化剂显示出更好的催化活性，实现了高达1800 TON的高TON值。还描述了通过氢转移过程用iPrOH前所未有地减少CO2。获得了高达150的TON值。另外两种仲醇，环己醇和1-苯基乙醇，也被用作还原二氧化碳的氢源。
A series of four Ir and Ru catalysts have been tested in the reduction of CO2 to formate in the presence of H2. The iridium catalysts containing the basic NHC ligands were the ones to show better catalytic activities, achieving high TON values of up to 1800 TON. The unprecedented reduction of CO2 with iPrOH through a hydrogen transfer process is also described. TON values of up to 150 were obtained. Two other secondary alcohols, cyclohexanol and 1-phenylethanol, were also used as hydrogen sources for the reduction of carbon dioxide.
