Research progress of metal-organic frameworks-based materials for CO2 capture and CO2-to-alcohols conversion.

[Display omitted] • The influencing factors of MOFs for CO 2 capture and CO 2 -to-alcohols are discussed. • Strategies for improving the CO 2 capture of MOFs-based materials are introduced. • The catalytic systems used for CO 2 -to-alcohols are summarized. • The hydrogenation pathway of CO 2 -to-alcohols by MOFs-based materials are presented. • The challenges and trends of MOFs in CO 2 capture and conversion are prospected. The global climate change caused by the continuous increase of carbon dioxide (CO 2) emissions has seriously threatened the survival of human beings, so it is imperative to control its emission reduction and achieve its utilization. The adsorption of CO 2 and conversion into high-value-added chemicals can not only reduce the exhaust emission of greenhouse gas, but also help to solve the problems of excessive dependence on fossil fuels and the storage of renewable energy. As a promising carbon recycling technology, carbon capture and utilization (CCU) has attracted wide attention in the past decades. Various functional materials such as metal-organic frameworks (MOFs), metal oxides, molecular sieves and porous carbon materials have sprung up for CO 2 capture and conversion. MOFs have become a more promising candidate due to their highly tunable pore structure, easy surface functionalization and abundant active sites. This paper reviews most studies published in the last five years on MOFs used for capturing CO 2 and CO 2 -to-alcohols conversion. The main topics include 1) The influencing factors of MOFs-based materials for CO 2 capture and CO 2 -to-alcohols; 2) strategies to improve CO 2 adsorption performance and the role of high throughput computational screening (HTCS) on the development and screening of MOFs adsorbent; 3) MOFs-based materials used for CO 2 -to-alcohols conversion in photo-, electro-, thermal-catalytic and their hybrid catalytic systems, as well as the corresponding mechanistic studies. The purpose of this review is to offer a technical and theoretical direction for the creation and industrial implementation of high-performance MOFs-based materials in the field of CO 2 adsorption and conversion, highlight the associated challenges and opportunities.
