This project plans to apply an innovative methodology to the selective conversion of carbon dioxide (CO2) waste into useful C1 chemicals. The new inorganic chemistry approach is based on the invention of transition metal–organic hydride coordination complexes, which are designed to punch hydride ion (= a proton and two electrons) into metal-activated CO2-derived intermediates. The approach should naturally overcome the two-electron barrier found for today's best transition metal electrocatalysts of CO2 reduction and, hence, enable the selective production of formaldehyde, a four-electron reduction product and bulk industrial feedstock chemical, or methanol, a six-electron reduction product and future transport fuel.

该项目计划采用一种创新方法，将二氧化碳废物有选择地转化为有用的C1化学品。新的无机化学方法基于过渡金属-有机氢化物配位络合物的发明，其被设计成将氢化物离子（=一个质子和两个电子）冲压成金属活化的CO2衍生的中间体。该方法应该自然地克服了当今最好的CO2还原过渡金属电催化剂所发现的双电子势垒，因此能够选择性地生产甲醛（四电子还原产物和大宗工业原料化学品）或甲醇（六电子还原产物和未来的运输燃料）。
