“…This material could be compared with porous carbon synthesized from other polymeric materials, which are usually produced in the range of 600-2000 m 2 g −1 . For Fe/C, the reduction of the specific surface area is likely due to the iron oxide in the material, which is non-porous and can induce mesoporous-graphitic structure (Prasetyo et al 2019;Amelia et al 2020). Fe/C and blank carbon material have mesoporous structure with a mean pore 3.72 nm and 2.61 nm.…”

This study examined roles of iron oxide/porous carbon material (Fe/C) for removing metronidazole in simulated wastewater by adsorption and then followed by a degradation using advanced oxidation process (H2O2, O3 and combination of H2O2/O3). Fe/C was produced by an impregnation of iron oxide precursors during resorcinol-formaldehyde synthesis followed by pyrolysis at 800 °C. For comparison, blank carbon (without iron loading) was also synthesized. The properties of porous carbon were investigated by SEM-EDX and N2-sorption analyzer. Blank carbon and Fe/C featured the specific surface area of 755 m2g-1 and 394 m2g-1, respectively. The loading of iron oxide altered the pore structures of material. The adsorption isotherm data were followed by the Langmuir isotherm model with metronidazole uptake up to 46.07 mg g-1 and 39.97 mg g-1 at 30oC by Fe/C and blank carbon. The degradation study was then carried out with catalyst dosage of 0.1 g/100 mL solution and 120 min reaction time at 30 oC. It is noticeably that, the degradation of metronidazole was better when a combination of H2O2/O3 was employed, compared with an individual of H2O2 or O3. Regarding the stability, Fe/C maintained its high activity upon four consecutive runs.

“…Several processes, such as humidity management and ethylene concentration control, are essential in increasing a product's shelf-life, and improving these processes is necessary to meet the markets demand. Cobalt may play a key role in the latter, as demonstrated by Prasetyo et al [102], who developed an adsorbent analogous for ethylene removal, during storage of fruit, based on Co-oxide-impregnated nanoporous carbon with substantial ethylene adsorption capacity, leading to an extended shelf life of these products. Nevertheless, although postharvest storage of horticultural products, especially fruits, is of crucial significance, the use of Co to promote product's shelf-life and availability to the public has still to be optimised and validated for larger-scale application.…”

Non-Essential Elements and Their Role in Sustainable Agriculture

Agricultural systems are constantly under environmental pressure, and the continuous rise of the global population requires an increasingly intensification of agronomical productivity. To meet the current global food demand, particularly in depleted ecosystems under adverse climate conditions, the development of novel agronomical practices, which ensure crop productivity while safeguarding minimal impact to the environment, must be encouraged. Since aluminium (Al), cobalt (Co), selenium (Se), silicon (Si) and sodium (Na) are not essential to plant metabolism, their benefits are often neglected or underestimated in agriculture; however, several studies support their advantages in sustainable agriculture when properly employed. The agronomical uses of these elements have been studied in the last decades, delivering important cues for the improvement of food and feed production worldwide due to beneficial effects in plant growth and productivity, nutrient balance, pest and pathogen resistance, water stress management, heavy-metal toxicity alleviation, and postharvest performance. However, their application has not been addressed as part of a holistic conservation strategy that supports the sustainability of agroecosystems. Here, we discuss the potential use of these elements in sustainable agriculture, and the knowledge gaps that hinder their effective integration into agronomical practices, which result in equally profitable applications while supporting environmental sustainability.

“…Porous carbon is a versatile material with wide applications, for example: in adsorption [ 1 ], separation [ 2 ], purification [ 3 ], gas storage [ 4 ], electrochemical storage [ 5 ] and catalysis [ 6 ] due to the advantageous properties of pore- and microstructures. There are many precursors for porous carbon preparation, for instance: biomass (natural polymer), synthetic polymer and metal carbide.…”

Porous carbon has been widely used for many applications e.g., adsorbents, catalysts, catalyst supports, energy storage and gas storage due to its outstanding properties. In this paper, characteristics of porous carbon prepared by carbonization of lignin from various biomasses are presented. Various biomasses, i.e., mangosteen peel, corncob and coconut shell, were processed using ethanol as an organosolv solvent. The obtained lignin was characterized using a Fourier transform infrared (FTIR) spectrophotometer and a viscosimeter to investigate the success of extraction and lignin properties. The results showed that high temperature is favorable for the extraction of lignin using the organosolv process. The FTIR spectra show the success of lignin extraction using the organosolv process because of its similarity to the standard lignin spectra. The carbonization process of lignin was performed at 600 and 850 °C to produce carbon from lignin, as well as to investigate the effect of temperature. A higher pyrolysis temperature will produce a porous carbon with a high specific surface area, but it will lower the yield of the produced carbon. At 850 °C temperature, the highest surface area up to 974 m2/g was achieved.
