Abstract
The high consumption of fossil energy has led to increasing concentrations of carbon dioxide (CO ) in the
2
atmosphere, making carbon capture and separation a research hotspot in this century. As novel porous materials,
metal-organic frameworks (MOFs) are widely used for CO capture due to their unique structures and tunable
2
properties. Currently, several relatively mature strategies have been applied to synthesize MOFs for CO capture.
2
Herein, we investigate strategies for tuning the pore windows, pore sizes, open metal sites, and post-synthesis or
pre-synthesis modifications of MOFs from the perspective of CO capture performance. Furthermore, we
2
summarize the relevant CO capture technologies and research advances and describe the application of different
2
strategies in the synthesis of CO capture-oriented MOFs.

Keywords: Metal-organic frameworks, carbon capture and separation, CO capture strategy

INTRODUCTION
Since the Industrial Revolution, the extraction and consumption of fossil fuels have caused a remarkable
expansion of greenhouse gases in the atmosphere. The Earth's climate is undergoing major changes
characterized by global warming, according to numerous authoritative studies . Compared to other
[1-4]
greenhouse gases, carbon dioxide (CO ) has a weaker greenhouse effect, but it has the highest proportion in
