“…[14] Within the broad range of possible precursor materials, natural materials such as olive stones did attract attention and were successfully activated by physical CO 2 activation. [198] Granular bed filters made from nanosilver/TiO 2 -chitosan composite could be produced by crosslinking colloidal suspensions of chitosan and TiO 2 . [199] During this process, beads were shaped using a peristaltic pump, and subsequently covered with silver NPs by photochemical deposition.…”

Particulate and gaseous air pollutants pose a threat to human health and contribute to climate change. By today, air filters, stationary and portable, are markedly improved and can often provide innocuous air pollution levels. After introducing the classification and standards on air filters, the influence of the processing route and its parameters on the resulting air filter properties and consequently its performance are discussed. Numerous tools are presented to adjust structural properties such as fiber or pore diameter, specific surface area, surface charge, hydrophilicity, or photocatalytic activity to achieve the desired performance in terms of high filtration efficiencies, sufficient mechanical stability, regeneration eligibility, antimicrobial and optical properties. In particular, inorganic and composite materials as well as nonfibrous structures are covered, which are currently holding an outsider position in an air filter community dominated by polymeric materials and fibrous structures.

“…Activated carbon can also be obtained from agricultural waste products rather than from fossil fuels ( Nowicki, Pietrzak, & Wachowska, 2009 ). On this note, Bader, Sager, Schneiderwind, and Ouederni (2019) successfully prepared foam and granular activated carbons from olive stone grains collected from olive oil factories through chemical and physical activation for adsorbing NO 2 . Results from the adsorption tests indicated higher adsorption capacity of NO 2 by CO 2 -activated carbon than KOH-activated carbon thus inferring that meso-microporous carbon activated with a strongly basic group is best suitable for adsorbing NO 2 .…”

Introduction The advent of COVID-19 has impinged millions of people. The increased concern of the virus spread in confined spaces due to meteorological factors has sequentially fostered the need to improve indoor air quality. Objective This paper aims to review control measures and preventive sustainable solutions for the future that can deliberately help in bringing down the impact of declined air quality and prevent future biological attacks from affecting the occupant’s health. Methodology Anontology chart is constructed based on the set objectives and review of all the possible measures to improve the indoor air quality taking into account the affecting parameters has been done. Observations An integrated approach considering non-pharmaceutical and engineering control measures together for a healthy indoor environment should be contemplated rather than discretizing the available solutions. Maintaining social distance by reducing occupant density and implementing a modified ventilation system with advance filters for decontamination of viral load can help in sustaining healthy indoor air quality. Conclusion The review paper in the main, provides a brief overview of all the improvement techniques bearing in mind thermal comfort and safety of occupants and looks for a common ground for all the technologies based on literature survey and offers recommendation for a sustainable future.

“…Activated carbon is widely used in various fields of water treatment (Oyim et al, 2022;Soliman et al, 2022), catalysts (Méndez et al, 2022a), gas storage (Ramesh et al, 2021), as well as the cosmetic and pharmaceutical industries (Hammani et al, 2019). In addition, activated carbon is usually also used for air filtration and treatment of exhaust gases or emissions (Bader et al, 2019;Rodríguez-Sánchez et al, 2022). Activated carbon is also a porous material that can be produced from agricultural and food waste (Daouda et al, 2021;Durán et al, 2022;Kosheleva et al, 2019;Nguyen et al, 2021;Ratan et al, 2018;Sujiono et al, 2022).…”

The emission of nitrogen oxide (NOx), nitrogen monoxide (NO) and carbon monoxide (CO) from vehicle exhaust gas generates an adverse effect to the environment as well as the human health. Therefore, the need to reduce such emission is urgent. The decrease of the emission can be achieved through the use of catalytic converter. This study explains the application of catalytic converter prepared from activated carbon to enhance the activity through its adsorption ability. The activated carbon was derived from banana peels after heating them up at 400 ºC for 1.5 hours and activation using natrium hydroxide (NaOH). Several techniques including N2 adsorption-desorption, X-Ray Diffraction (XRD), Scanning Electron Microscopy-Electron Dispersive X-ray (SEM-EDX), and Fourier Transform Infrared (FTIR) were adopted to characterize the activated carbon properties. The activated carbon formed was then coated with copper. The activity of the catalytic converter using activated carbon coated with copper was then tested for its performance on diesel engine Yanmar TF 70 LY-DI with variations in the number of catalyst layers, namely 1 layer (C1), 2 layers (C2) and 3 layers (C3). Sample with three layers (C3) of catalyst exhibited the highest activity with the percentage efficiency in reducing emissions concentration of 48.76 %; 31.27 % and 29.35 % for NOx, NO and CO, respectively.
