“…The superior degradation efficiency (~ 100% removal in 20 min) of trichloroethylene by biochar-supported nZVI under groundwater condition (bicarbonate buffer solution at pH 8.2) showed that the superoxide radical and singlet oxygen mediated by Fe 0 and oxygen-containing group (C=O) were the major reactive oxygen species for trichloroethylene dichlorination (Li et al 2020b). Photocatalytic degradation of MB by ZnO-loaded biochar (ZnO-BC) composites at pH 7.0 under UV illumination conditions showed 99% MB degradation efficiency within 30 min, and the presence of metal ions and other organic pollutants hardly affected MB photocatalytic degradation (Chen et al 2019a). The photocatalytic degradation efficiency of MB on TiO 2 -biochar was 21% higher than that of TiO 2 nanoparticles alone (Safari et al 2019).…”

Biochar have received multidisciplinary attention because of their extraordinary physicochemical properties. In this review, the application of biochar and biochar-based materials for the efficient elimination of organic and inorganic pollutants are summarized. The sorption of organic chemicals and heavy metal ions/radionuclides, degradation/transformation of organic pollutants, and sorption-reduction-solidification of high-valent metal ions are described in detail. The interaction mechanism at molecular level from advanced spectroscopic techniques and theoretical calculations is discussed. Finally, the challenges in the application of biochar and biochar-supported materials in the immobilization of heavy metal ions and photocatalytic degradation of persistent organic pollutants in soils or wastewater are pointed out. This review is helpful for the graduate students to understand the recent works about biochar and biochar-supported materials in environmental pollutants management.

“…Macroalgae are rich in bioactive amines, sulfates, carboxyl, and hydroxyl compounds, properties that facilitate the binding of dye molecules on the surface of macroalgae-derived biochar (Ahmed et al 2019;Gokulan et al 2019). Another attractive method for the removal of dyes was photodegradation (Chen et al 2019e;Khataee et al 2019;Sharma et al 2019;Zhai et al 2019).…”

“…However, little information is available about the degradation of antibiotics, methylene blue dye, PAHs and other macromolecular organic pollutants by microorganism immobilized on biochar. Such organic pollutants are mainly degraded by chemical methods mediated by free radical oxidation through activating persulfate/H 2 O 2 or photocatalysis by biochar (Chen et al 2019e;Deng et al 2019a;Li et al 2019c;Liang et al 2019a). The generation of free radicals during chemical degradation of organic pollutants would cause ecotoxicological risk.…”

Biochar, derived from thermal pyrolysis of biomass, has been regarded as a low-cost, sustainable and beneficial material and widely applied in agriculture, environment and energy during the last two decades. To elucidate the research status timely and future trends in biochar field, CiteSpace is used to systematically analyze the related literature retrieved from the Web of Science core collection in 2019. Based on the keywords clustering analysis, it was found that "biochar production", "organic pollutants removal", "heavy metals immobilization", "bioremediation" were the main hotspots in research covering biochar. "Bioremediation" is an emerging topic and deserves extensive attention due to its highly effective and environmentally friendly treatment of pollutants. Improving the phytoremediation effect, immobilizing functional microorganisms on biochar, and using microorganisms as raw materials to produce biochar were the common methods of biochar-assisted bioremediation. While studies focused on "soil quality and plant growth" and "biochar and global climate change" decreased, investigations concentrated in the toxicity of biochar to soil biota and ruminants are sustainably growing. Research on direct and catalytic thermal pyrolysis of green waste (mainly microalgae) for biofuels (bio-oil, biodiesel, syngas, etc.) and biochar production is increasing. Converting municipal wastes (e.g., sewage sludge, fallen leaves) into biochar through pyrolysis was a suitable treatment for municipal waste and became a popular topic in recent time. Moreover, the biochar produced from these municipal wastes exhibited excellent performance in the removal of pollutants from wastewater and soil. This review may help to identify future directions in biochar research and applications.

“…[62] Another study reported the fabrication of ZnO-loaded biomass porous carbon prepared through pyrolysis of jute fibers and was successfully used for the removal of MB. [75] The researchers also noted that the removal of MB is pH-dependent, and the optimized removal efficiency reached up to 99 % at pH 7.0 following 30 min of UV illumination. Similar to Cu 2 + removal, Ngoc Hoa Phan et al investigated the removal of dye using JDAC and coconut-fiber-derived AC prepared by physical and chemical processes.…”

“…Dyes in the form of colored wastewater are highly toxic effluents when released into environmental water bodies. [75] It is estimated that around 1-15 % of dyes are lost during dying processes, [76] and more than 10 000 different colors and dyes are used industrially all over the world. [77] Dyes in water-even in very low concentrations-are easily visible and aesthetically unacceptable.…”

This article summarizes the preparation and applications of carbon derived from jute sticks and fibers that are low‐cost, widely available, renewable, and environmentally friendly. Both the fibers and sticks are considered ideal candidates of carbon preparation because they are composed of cellulose, hemicelluloses, and lignin, and contain negligible ash content. Various carbon preparation methods including simple pyrolysis, pyrolysis with chemical and physical activations are discussed. The impacts of several parameters including types of activating agents, impregnation ratio, and temperature on their morphology, surface area, pore size, crystallinity, and surface functional groups are also emphasized. Various treatments to endow functionalization for increasing the practical applicability, such as chemical, physical, and physico‐chemical methods, are discussed. In addition, applications of jute‐derived carbon in various practical areas, including energy storage, water treatment, and sensors, are also highlighted in this report. Due to the porous fine structure and a large specific surface area, the jute‐derived carbon could be considered as a powerful candidate material for various industrial applications. Finally, possible future prospects of jute‐derived carbon for various applications are pointed out.
