Surface, Interface and Structure Optimization of Metal‐Organic Frameworks: Towards Efficient Resourceful Conversion of Industrial Waste Gases

Abstract

Industrial waste gas emissions from fossil fuel over‐exploitation have aroused great attention in modern society. Recently, metal‐organic frameworks (MOFs) have been developed in the capture and catalytic conversion of industrial exhaust gases such as SO2, H2S, NOx, CO2, CO, etc. Based on these resourceful conversion applications, in this review, we summarize the crucial role of the surface, interface, and structure optimization of MOFs for performance enhancement. The main points include (1) adsorption enhancement of target molecules by surface functional modification, (2) promotion of catalytic reaction kinetics through enhanced coupling in interfaces, and (3) adaptive matching of guest molecules by structural and pore size modulation. We expect that this review will provide valuable references and illumination for the design and development of MOF and related materials with excellent exhaust gas treatment performance.

Boosting urea synthesis in simulated flue gas electroreduction by adjusting W–W electronic properties

“…[1][2][3] The recycling and utilization of carbon in flue gas have attracted great attention as these approaches have the potential to alleviate climate change and energy consumption. [4][5][6] Electrocatalytic technology had initially attempted to utilize carbon resources in flue gas, i.e. to reduce CO 2 to valuable chemicals.…”

Review and Perspectives of Monolithic Metal–Organic Frameworks: Toward Industrial Applications

“…7−9 MOFs exist in the form of powder crystallites, which are widely used in energy storage and transfer, pollution control, and other industrial processes. 10 For instance, in industrial production, 11 waste gas 12 is continuously discharged, thereby continuously intensifying air pollution. 13 Traditional methods use modified silica to capture SOx/NOx and CO 2 ; however, the deactivation of toxic chemical adsorbents and amine adsorption sites and amination of solids can adversely affect adsorbents, as an alternative to traditional porous materials.…”
