提出了用于还原 CO(2) 和碳酸氢盐的最有效、稳定且易于合成的非贵金属催化剂体系。在铁(II)-氟-三(2-(二苯基膦基)苯基)膦基]四氟硼酸盐配合物3的存在下，碳酸氢盐的氢化反应以良好的收率进行，并且具有高催化剂生产率和活性（TON > 7500，TOF > 750）。二氧化碳加氢的高压核磁共振研究表明，相应的铁-氢化二氢络合物 4 在催化循环中至关重要。
The most efficient, stable, and easy-to-synthesize non-noble metal catalyst system for the reduction of CO(2) and bicarbonates is presented. In the presence of the iron(II)-fluoro-tris(2-(diphenylphosphino)phenyl)phosphino]tetrafluoroborate complex 3, the hydrogenation of bicarbonates proceeds in good yields with high catalyst productivity and activity (TON > 7500, TOF > 750). High-pressure NMR studies of the hydrogenation of carbon dioxide demonstrate that the corresponding iron-hydridodihydrogen complex 4 is crucial in the catalytic cycle.
