“…In addition to current activation methods, Ahmed et al [ 61 ] produced AC from woody biomass using less chemicals by conducting a prepyrolysis step at 360 °C for 1 h before chemical activation. As shown in Figure 4 a, this approach resulted in a 70% reduced chemical use.…”

Carbon and its derivatives such as graphene, activated carbon, and carbon aerogel, with diversity in morphology and structure, large surface area, and high electrical conductivity become ideal candidates in the growing field of energy. To meet the ever‐increasing energy demand and the development of green and sustainable energy sources, the utilization of biomass and industrial wastes as a carbon precursor has attracted great attention. In recent years, several attempts have been transpired to convert biomass sources and industrial wastes into value‐added carbon materials. However, not all reported precursors are suitable for practical energy applications. Furthermore, the lack of correlation between the characteristics of fabricated carbonaceous materials with desired properties for the energy field has dimmed the utilization of these materials in high‐performance energy‐storage devices. The purpose herein is to summarize the latest progress in this field as well as discuss the limitations on the commercialization of these materials along with possible solutions to remedy the drawbacks and improve the electrochemical performance of biomass and waste‐derived carbon materials.

“…Next, heat treatment is applied in an inert atmosphere (various/high temperatures) [20]. Generally, compared with physically activated AC, chemically activated AC has a larger surface area and a smaller pore size, with a wider range of applications [21].…”

Innovative actions towards a pollution free-planet" is a goal of the United Nations Environment Assembly (UNEA). Aided by both the Food and Agricultural Organisation (FAO) and its Global Soil Partnership under the 3rd UNEA resolution, a consensus from > 170 countries have agreed a need for accelerated action and collaboration to combat soil pollution. This initiative has been tasked to find new and improved solutions to prevent and reduce soil pollution, and it is in this context that this review provides an updated perspective on an emerging technology platform that has already provided demonstrable utility for measurement, mapping, and monitoring of toxic trace elements (TTEs) in soils, in addition to the entrapment, removal, and remediation of pollutant sources. In this article, the development and characteristics of functionalized mesoporous silica nanomaterials (FMSN) will be discussed and compared with other common metal scavenging materials. The chemistries of the common functionalizations will be reviewed, in addition to providing an outlook on some of the future directions/applications of FMSN. The use of FMSN in soil will be considered with some specific case studies focusing on Hg and As. Finally, the advantages and developments of FMSN in the widely used diffusive gradients-in-thin films (DGT) technique will be discussed, in particular, its advantages as a DGT substrate for integration with oxygen planar optodes in multilayer systems that provide 2D mapping of metal pollutant fluxes at submillimeter resolution, which can be used to measure detailed sediment-water fluxes as well as soil-root interactions, to predict plant uptake and bioavailability.

“…However, commercial AC is usually costly. The use of agricultural by-products as raw materials for AC production could potentially be cheaper since these raw materials are renewable and considered waste [10][11][12].…”

This study examined the applicability of oil palm frond-activated carbon (OPF-AC) as adsorbent in the treatment of landfill leachate. OPF-AC was prepared by mixing granular OPF with an aqueous solution composed of distilled water and zinc chloride (ZnCl2) at different ratios. Batch experiment studies were carried out to investigate the optimum OPF-AC dosage as well as the optimum shaking time. The optimum condition was achieved at 1.2 g of OPF-AC dosage and 50 minutes of shaking time. The highest removals of COD, color and Fe (77%, 75% and 69%, respectively) were obtained at the optimum condition. Meanwhile, the adsorption capacities were 146.93 mg/g (COD), 56.43 mg/g (color) and 0.11 mg/g (Fe). The increase in adsorbent dosage also resulted in a larger free surface area and exchangeable binding sites. However, the unsaturation of adsorption sites during the adsorption process resulted in a slight drop in removal efficiency of COD, color, and Fe. Furthermore, due to the aggregation and overcrowding of adsorbent particles, the use of a greater amount of adsorbent dosage imposed particle interactions.
