Biomass/Biochar carbon materials for CO2 capture and sequestration by cyclic adsorption processes: A review and prospects for future directions

Abstract: • Key aspects of cyclic adsorption processes (PSA, TSA, VSA etc.) are discussed. • Main concepts of derived adsorbents from biomass/biochar are presented. • A review on developed cyclic adsorption processes using biomass/biochar is illustrated. • Biomass/biochar are introduced as future studies for cyclic adsorption processes. The persistent enhancement of greenhouse gases in the atmosphere originated from anthropogenic activities, especially CO 2 , resulted in several serious global challenges. In this way, employing biomass, biochar, etc., as a low-cost precursor for CO 2 adsorbent is promising not only in the view of hydrophobic character and abundant resources, but also is an illustrious strategy for solid wastes management as a consequence of the exponential population expansion. Herein, key concepts on adsorption technology, waste management, and different activation techniques on raw carbons materials have firstly been discussed. Afterwards, almost all accomplished studies on cyclic adsorption processes e.g. PSA, TSA, VSA, etc., which employed biomass/biochar as a source of adsorbents have been extensively reviewed, that gives a precise knowledge for large scale application of these materials. Furthermore, in the last part of this work, biomass/biochar adsorbent based samples, which have already been studied for CO 2 capture, but till now, they have not been evaluated at the bench/pilot scale by cyclic adsorption process, are introduced for future directions. Also for the reader’s of this work, key concepts of each section have been summarized in the form of simple figures and tables that will help to identify clearly the prominent accomplished works till now.

Management of surgical mask waste to activated carbons for CO2 capture

Abstract: The worldwide COVID-19 pandemic has resulted in a huge amount of face masks being used up and thrown away, resulting in increased environmental pollution and infection risks. In our work, we have developed a highly efficient process of neutralizing face mask waste into a useful carbon material. Then, the prepared activated carbon was used for CO2 adsorption studies. A series of activated carbons from face masks used as a precursor were synthesized using KOH and the activation temperature was in the range of 600-800 °C. All materials were characterized by well-developed porosity. The influence of activation temperature on the textural properties of prepared activated carbons and their adsorption abilities were investigated. The highest CO2 adsorption was received for the M_800 carbon and it was 3.91 mmol/g at the temperature of 0 °C and the pressure of 1 bar. M_800 carbon exhibited also high selectivity of CO2 over N2. Seven equilibrium isotherms were applied to the experimental data to find out the best fit (Langmuir, Freundlich, Sips, Toth, Unilan, Fritz-Schlunder and Radke-Prausnitz isotherms). The presented research provides an environmentally friendly and cost-effective method of recycling waste masks into a valuable product in the form of carbon and its potential use in the absorption of harmful CO2 influencing the greenhouse effect.

Research progress on CO2 capture and utilization technology

Abstract: With the expansion of industry, the emission of greenhouse gases is increasing, and its impact on climate is becoming more and more serious. CO 2 is the main culprit of the greenhouse effect, and how to effectively solve the climate problem caused by CO 2 has attracted more and more attention. In recent years, there have been continuous attempts to reduce CO 2 emissions from the source, but no obvious results have been achieved. In fact, CO 2 is not only a greenhouse gas, but also a potential carbon resource. Therefore, how to capture and effectively use CO 2 is also the research direction that many scholars have been exploring recently. In this paper, the current situations of CO 2 capture technologies are reviewed from the aspects of chemical absorption, solid-phase porous materials adsorption, membrane separation, cryogenic separation, hydrate method and microbiological method in the first part. Then, the CO 2 utilization technologies are systematically introduced from the aspect of physical utilization, chemical utilization, biological utilization and mineralization utilization. Furthermore, several representative frontier technologies of CO 2 resource utilization are reported. On this basis, the advantages and disadvantages of different methods are summarized to provide some ideas and references for alleviating the CO 2 issue. • Various traditional and novel CO 2 capture and utilization technologies are summarized. • The challenges and future prospects of CO 2 capture and utilization technologies are analyzed. • The application of CO 2 capture technologies in basic industry and pilot plants is reviewed. • The frontier reports of CO 2 resource utilization in different research directions are reviewed.

Nanoarchitectonics of low-dimensional metal-organic frameworks toward photo/electrochemical CO2 reduction reactions

Abstract: • Top-down and bottom-up synthetic methods of LD MOFs are reviewed and compared. • The impacts of LD MOFs catalysts’ physiochemical properties on CO 2 reduction reaction are discussed. • Important tools and methods are proposed for guiding the synthesis of novel LD MOFs CO 2 reduction catalysts with high activity. Low-dimensional metal-organic frameworks (LD MOFs) have attracted increasing attention in recent years. Their unique properties, including ultrathin structures, fully exposed active sites, and tunable compositions make them excellent catalysts for CO 2 catalytic reduction. Even though numerous efforts have been attempted to modify the morphologies of LD MOFs, it is still highly important to explore the synthetic principles and catalytic properties of LD MOFs. In this review, various synthetic methods for preparing LD MOFs are summarized. The unique properties and applications of LD MOFs in CO 2 catalytic reduction reaction are introduced and discussed. Finally, several challenges and prospects of this emerging research field are proposed. The present review could provide a comprehensive understanding on the design and synthesis of LD MOFs for CO 2 reduction.

Zeolite-based catalyst for direct conversion of CO2 to C2+ hydrocarbon: A review

Abstract: Capturing CO2 and converting it into fuels or fine chemicals is a promising way to deal with climate change issues and energy crises. However, the conversion of CO2 into hydrocarbons requires high activation energy owing to the stable CO bond. Therefore a catalyst with high performance is necessary to facilitate the chemical reactions. In recent years, it has been demonstrated that catalysts based on metal or metal oxides combined with zeolites have excellent performances in converting CO2 to various hydrocarbons and have the potential to be applied at an industrial scale. The present review article highlights the progress of zeolite-based catalysts in the CO2 conversion to hydrocarbon, i.e., gasoline, olefins, and aromatics products through modified Fischer-Tropcsh and methanol mediated pathways. The effect of zeolite properties, e.g., topology, acidity, morphology, crystallite size, extra framework cation and atom, and the pore structure, has been discussed. Also, several synthetic strategies for precisely adjusting the zeolite properties were demonstrated. Finally, the insight for future development was proposed.
