Abstract Biochar and biochar-based materials have been studied extensively in multidisciplinary areas because of their outstanding physicochemical properties. In this review article, biochar the removal environmental pollutants, hydrogen generation carbon dioxide capture were summarized compared. The interaction mechanisms discussed from experimental results characterization analysis. high porous structures, active surface sites, (co)doping single metals/nonmetals, incorporation metal oxides or other improved activity applications. However, there are still some challenges such as: (1) fact that H 2 with selectivity produced syngas to meet real application requirement industrial is main challenge production; (2) selective CO stability, adsorption capacity recyclability at low-cost should be considered focused on; (3) sorption-(photo)degradation organic chemicals; (4) sorption-reduction-extraction/solidification metals/radionuclides efficient methods for elimination pollutants. end, perspectives, possible techniques materials’ future described.

Use of biochar as a sustainable agronomic tool, its limitations and impact on environment: a review

Discover Agriculture, Год журнала: 2024, Номер 2(1)

Опубликована: Май 28, 2024

Abstract Ensuring global food security under present and futuristic scenario of climate change accompanied by expanding population is major concern worldwide. Researchers across the world are focusing on sustainable agronomic practices to combat induced issues like desertification, reduction in crop yield, pest outbreaks, soil health. Biochar has demonstrated positive effects plant growth, development, fruit quality, carbon capture sequestration. Studies indicate that biochar amendments can enhance health, growth development as well help combating abiotic stressors. several properties make it an attractive amendment, including high porosity, surface area, water-holding capacity, ability increase microbiota, which turn promote nutrient uptake reduce erosion. Environmentally, biochar’s degrade organic pollutant sequester makes a very addition agriculture. Nonetheless, also been reported have potential hazardous impacts human health associated with possible leakage toxic elements particulate matter pollution. However, lack exhaustive studies detail all aspects application agroecosystem impedes decision making its overall usability There exists need for comprehensive review cover important supplementation. This provides thorough overview multifaceted biochar, encompassing soil, environment, while exploring limitations along application.

Abstract Bamboo biochar was modified by lignin impregnation and microwave irradiation to enhance its performance for CO 2 capture. The pore structure of lignin-impregnated significantly affected the ratio. maximum specific surface area 377.32 m g −1 micropore volume 0.163 cm 3 were observed on with an ratio 1:20 (mass biochar). Lignin increased adsorption capacity up 134.46 mg . Correlation analysis confirmed crucial role biochar’s in adsorption. Avrami model fitted capture curves well. calculation activation energy suggested that process dominated physical mechanism assisted partial chemical mechanism. Meanwhile, Langmuir isotherm indicated transformed larger pores into more uniform micropores, thereby making closer monolayer Both high reusability (89.79–99.06%) after 10 successive cycles excellent selectivity competitive is outstanding adsorbent Graphical
