The SEM images of activated samples PC-Z and PC-H exhibit a significant distinction in the microscopic morphology and porous structure with different sizes and shapes [ 44 ]. Both materials show a hierarchical porous structure with several pore sizes and rough surfaces.…”

In this work was made a brief review of the main uses of bamboo charcoal. Several uses were found, the main ones being: treating water and effluents, improving the structure and fertility of soil adsorbent of vapors and odors to improve air quality inside buildings, remove oil spilled at sea, absorbing and diffusing electromagnetic and acoustics waves, acoustic treatment of indoor environments, emergency treatment against poisoning by ingestion, among other uses. The work also was discussed the process of carbonization of bamboo and was shown a portable equipment for the production of charcoal on a small scale. Was analyzed some properties of charcoal from bamboos of the following species: Phyllostachys pubescens (mossô bamboo), Bambusa tuldoides, Dendrocalamus asper (giant bamboo) and Bambusa vulgaris vittata (Brazilian bamboo).

“…Although many carbon capture materials, such as metal-organic frameworks (MOFs), zeolites, carbon nanotubes (CNTs), cellulose, silica gel, polymers, and others, have been developed, they require extreme cost or low efficiency for low-concentration CO 2 [19,20]. MOFs are arguably the most porous adsorbents in the market today.…”

“…However, its availability is increasingly limited due to environmental protection, natural resource conservation, and other competing applications of the palm fruit [19]. As a result, AC manufacturers are opting for more readily available stock materials for efficient ACs, such as bamboo [20,22]. Although recently developed bamboo-based ACs are applied in water purification, the adsorbent's structure is considered helpful in capturing gaseous pollutants because of the similar cellulose and lignin components to those of coconut shell, which usually results in highly developed micropores through carbonization [19,23,24].…”

This study fabricated a low-cost activated carbon (AC) adsorbent from readily available bamboo trees to control indoor CO2 levels and reduce energy costs associated with sustaining clean indoor air. Bamboo is naturally high in potassium content and has narrow fibrous channels that could enhance selective CO2 adsorption. The prepared bamboo-based activated carbon (BAC) exhibits predominantly micropores with an average pore size of 0.17 nm and a specific surface area of 984 m2/g. Upon amination, amine functionalities, such as pyridine, pyrrole, and quaternary N, were formed on its surface, enhancing its CO2 adsorption capacity of 0.98 and 1.80 mmol/g for low-level (3000 ppm) and pure CO2 flows at the ambient condition, respectively. In addition, the 0.3% CO2/N2 selectivity (αs,g) of the prepared sorbents revealed a superior affinity of CO2 by BAC (8.60) over coconut shell-based adsorbents (1.16–1.38). Furthermore, amination enhanced BAC’s CO2αs,g to 13.4. These results exhibit this sustainable approach's potential capabilities to ensure the control of indoor CO2 levels, thereby reducing the cost associated with mechanical ventilation systems. Further research should test the new sorbent’s adsorption properties (isotherm, kinetics, and thermodynamics) for real-life applicability.
