Hetero-Metallic Metal-Organic Frameworks for Photoreduction of CO2 to C2+ Hydrocarbons

在这个项目中，我们将专注于高效的可见光驱动的光还原二氧化碳以产生高附加值的C2+产品，而不是密集报道的C1产品，这将有望消除全球大量二氧化碳排放的影响，并产生有价值的碳氢化合物。过渡金属，如铜、铁、镍和钴，将被纳入到钛(IV)-有机骨架(金属-有机骨架)的结构中。我们将评估所制备的催化剂对C2+烃类产物的催化性能。用X射线吸收近边结构(XANES)、非弹性中子散射(INS)、对分布函数(PDF)和电光能谱等手段对催化剂的空间分布和电子转移过程进行了全面的表征。优化后的催化剂将被放大，并在大规模反应中进行性能评估。

In this project, we will be focusing on the efficient visible-light-driven photoreduction of CO2 to produce high-value-added C2+products rather than intensively reported C1 ones, which will hopefully eliminate the impact of the massive global CO2 emission andproduce valuable hydrocarbons. Transition metals, such as Cu, Fe, Ni, and Co, will be incorporated into the structure of Ti(IV)-MOFs(Metal-organic Frameworks). We will evaluate the catalytic performance of the prepared catalysts to target C2+ hydrocarbonproducts. Full characterization, including X-ray absorption near edge structure (XANES), inelastic neutron scattering (INS), pairdistribution function (PDF), and electro-optics spectroscopies will be applied to analyze the spatial distribution and electron transferprocess of the catalysts. The optimized catalysts will be scaled up and performance evaluated in large-scale reactions.
