Feasible fabrication of highly dispersed La2O3 promoted MgO composites for CO2 capture at mid-temperature

Mesoporous carbon nitride supported MgO for enhanced CO2 capture

“…Magnesium oxide (MgO) stands out as one of the most auspicious contender materials for CO 2 capture thanks to its effective CO 2 capture over an expansive temperature spectrum together with reduced energy demands for CO 2 regeneration (Pang et al 2021;Li et al 2013;Pu et al 2021;Guo et al 2022). Besides, MgO is environmentally benign and can be prepared in bulk amounts at a low cost due to its abundant occurrence in nature (Pang et al 2021;Bahadoran et al 2022b).…”

“…Carbon nitride is a type of two-dimensional material that is being researched more and more due to its interesting combination of incomparable properties, such as easy and inexpensive synthesis, environmental benignity, inherent basicity, low density, biocompatibility, hardness, and superior electronic and electric features (Idris and Devaraj 2019;Oh et al 2015;Liu et al 2021;Park et al 2017;Ha et al 2019). In addition, the existence of nitrogen atoms in the structural framework of carbon nitride can not only endow the material with heightened thermal, chemical, and mechanical stabilities but also provide its surface with inherent basic functionalities (Jin et al 2009;Ekanayake et al 2021;Guo et al 2022;Jo et al 2017). The combination of these attractive attributes has endowed carbon nitride with a high potential of being employed in miscellaneous important applications, such as energy storage and conversion, catalysis, sensing, and gas capture.…”

Mg–O–F Nanocomposite Catalysts Defend against Global Warming via the Efficient, Dynamic, and Rapid Capture of CO2 at Different Temperatures under Ambient Pressure

“…Currently, the CO 2 adsorption technique is used on some highly active materials, such as basic metal oxides, to combat global warming. In the pure form or promoted with other materials, MgO is regarded as a cornerstone component in all prepared materials for CO 2 capture purposes, among these basic metal oxides. − This characteristic relates to the abundance and strength of basic sites over the MgO surface. − Other types of adsorbents, including the reduced graphene oxide–MnO 2 nanocomposite, nickel–lithium silicate for CO 2 capture and subsequent production of CH 4 , Li 4 SiO 4 -based sorbents for high-temperature CO 2 capture, NiO-functionalized ultra-stable Y zeolite, Mg–Al mixed metal oxides for high-temperature CO 2 capture, alumina-supported layered double hydroxides, CuAl 2 O 4 nanoplates, Ni–CaO dual function materials, and CaO–Fe 2 O 3 –SiO 2 composite, have been extensively examined . Few articles have focused on the study of capturing CO 2 in a dynamic mode at different temperatures by flowing CO 2 gas at different rates through the adsorbents. , Many review articles with a forward-looking perspective discussed various CO 2 capture techniques − utilizing different adsorbent materials.…”
