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

在本项目中，我们将专注于高效可见光驱动的CO2光还原，以生产高附加值的C2+产品，而不是集中报道的C1产品，这将有望消除全球大量CO2排放的影响，并生产有价值的碳氢化合物。过渡金属如Cu、Fe、Ni和Co将被引入Ti（IV）-MOF（金属有机框架）的结构中。我们将评价所制备的催化剂对目标C2+烃产物的催化性能。利用X射线吸收近边结构（XANES）、非弹性中子散射（INS）、电子对分布函数（PDF）和电光光谱等表征手段分析了催化剂的空间分布和电子转移过程。优化后的催化剂将在大规模反应中进行放大和性能评估。

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.
