The atmospheric CO2 concentration continues a rapid increase to its current record high value of 416 ppm for the time being. It calls advanced capture technologies. One attractive technologies is physical adsorption-based separation, which shows easy regeneration and cycle stability, thus reduced energy penalties cost. extensive research on this topic evidenced by growing body scientific technical literature. progress spans from innovation novel porous adsorbents practical separation practices. Major materials include most widely used industrially relevant carbons, zeolites, activated alumina, mesoporous silica, newly emerging metal-organic frameworks (MOFs) covalent-organic framework (COFs). key intrinsic properties such as pore structure, surface chemistry, preferable adsorption sites, other structural features that would affect capacity, selectivity, recyclability are first discussed. industrial variables particle size adsorbents, mechanical strength, heat management, technological advances equally important, even more crucial when scaling up bench pilot-scale demonstration commercial scale. Therefore, we aim bring full picture technologies, adsorbent design, property evaluation performance assessment not only under ideal equilibrium conditions but also in realistic pressure swing processes.

Water treatment is crucial to improve the water quality and reduce diarrheal chronological diseases caused by excessive discharge of organic dyes other waste. The development expansion efficient catalysts for degradation sterilization has attracted widespread attention. Herein, we report an example a porphyrin-based two-dimensional layered metal-organic framework (MOF) (2DZnTcpp) its sono-/photocatalytic bactericidal activity. dislocated layers effectively avoid close π-π stacking provide porous space oxygen/water/dye contact. introduction Zn ions increases spin orbital coupling through heavy atom effect promotes intersystem crossing process singlet oxygen generation. effective ligand-to-metal charge transfer open catalytic sites also facilitate splitting hydroxyl radical These features together promote reactive species (ROS) generation 2DZnTcpp under light illumination or ultrasound sonication. It worth noting that with high specific surface area porosity shows dye Moreover, could largely inactivate Escherichia coli irradiation (the power 1 sun) sonication 30 min efficiencies over 99.99999%. This work provides approach design synthesis MOF-based sono-/photocatalysts used in purification textile wastewater committed establishment more efficient, fast, environmentally friendly system.

Emerging Trends in Sustainable CO₂‐Management Materials

Advanced Materials, Год журнала: 2022, Номер 34(29)

Опубликована: Март 21, 2022

Abstract With the rising level of atmospheric CO 2 worsening climate change, a promising global movement toward carbon neutrality is forming. Sustainable management based on capture and utilization (CCU) has garnered considerable interest due to its critical role in resolving emission‐control energy‐supply challenges. Here, comprehensive review presented that summarizes state‐of‐the‐art progress developing materials for sustainable terms not only capture, catalytic conversion (thermochemistry, electrochemistry, photochemistry, possible combinations), direct utilization, but also emerging integrated situ as well artificial‐intelligence‐driven smart material study. In particular, insights span multiple scopes research are offered, ranging from mechanistic comprehension reactions, rational design precise manipulation key (e.g., nanomaterials, metal–organic frameworks, covalent organic zeolites, ionic liquids), industrial implementation. This concludes with summary new perspectives, especially aspects society, which major difficulties future potential implementing advanced technologies management. work may serve guideline road map CCU systems, benefiting both scientists engineers working this growing potentially game‐changing area.
