“…When the dosage of nZVI@ BC is less than 2.0 g L − 1 , the positive correlation between nZVI@BC dosage and atrazine elimination is observed owing to the increased available reactive sites. Moreover, an analogous trend is also observed in the effect of PMS concentration on atrazine dissipation (Diao et al 2021). Globally, phthalate esters (PAEs) are widely used in plastic products as typical plasticizers, which can present potential bioaccumulation of benzene carboxylic groups.…”

Biochar (BC) and nanoparticle-decorated biochar (NPs@BC) have emerged as potential high-performance function materials to facilitate simultaneous soil remediation and agricultural production. Therefore, there is an urgent need to incorporate environmental sustainability and human health targets into BC and NPs@BC selection and design processes. In contrast to extensive research on the preparation, modification, and environmental application of BC to soil ecosystems, reports about the adapted framework and material selection strategy of NPs@BC under environmental and human health considerations are still limited. Nevertheless, few studies systematically explored the impact of NPs@BC on soil ecosystems, including soil biota, geochemical properties, and nutrient cycles, which are critical for large-scale utilization as a multifunctional product. The main objective of this systematic literature review is to show the high degrees of contaminant removal for different heavy metals and organic pollutants, and to quantify the economic, environmental, and toxicological outcomes of NPs@BC in the context of sustainable agriculture. To address this need, in this review, we summarized synthesis techniques and characterization, and highlighted a linkage between the evolution of NPs@BC properties with the framework for sustainable NPs@BC selection and design based on environmental effects, hazards, and economic considerations. Then, research advances in contaminant remediation for heavy metals and organic pollutants of NPs@BC are minutely discussed. Eventually, NPs@BC positively acts on sustainable agriculture, which is declared. In the meantime, evaluating from the perspective of plant growth, soil characterizations as well as carbon and nitrogen cycle was conducted, which is critical for comprehending the NPs@BC environmental sustainability. Our work may develop a potential framework that can inform decision-making for the use of NPs@BC to facilitate promising environmental applications and prevent unintended consequences, and is expected to guide and boost the development of highly efficient NPs@BC for sustainable agriculture and environmental applications.

“…Certain types of iron–biochar composites, such as nZVI–biochar and FeS–biochar have a high reduction potential towards organic contaminants and the Cr(VI), since they can provide Fe(0), Fe(II) and S(II) species (Chen et al, 2020; Liu et al, 2020; Lyu et al, 2018). Iron–biochar composites can also activate oxidants to generate reactive oxygen species (ROS) for the oxidation of organic contaminants (Diao et al, 2020; Park et al, 2018). It is noteworthy that multiple iron species may be present in iron–biochar composites simultaneously, enhancing the performances of biochar through various mechanisms.…”

, ·OH and 1 O 2 . Compared with the virgin biochar and nZVI, the novel biochar composite revealed a synergistic effect on peroxymonosulphate activation and atrazine degradation (degradation rates of 40%, 55% and 96% for biochar–PMS, nZVI–PMS and biochar composite–PMS systems, respectively) (Diao et al, 2020). Considering that sulphate radical‐based advanced oxidation is a low‐impact remediation strategy with excellent performance (Hou, 2020), application of these biochar composites for the catalytic generation of ROS in this system aligns well with the concept of green and sustainable remediation (GSR).…”

“…To increase the crop yield for degraded soils (SDG 2 – zero hunger), mineral‐rich biochar composites as slow‐release fertilizers can be fabricated in a simple way, and further used for large‐scale applications (Chen et al, 2017; Hu et al, 2019). To promote human's good health and well‐being (SDG 3), the application of iron–biochar, LDH–biochar and microbial‐inoculated biochar composites would immobilize metals or degrade organic contaminants in soil (Diao et al, 2020; Feng et al, 2020; Gao et al, 2020). Numerous attempts have been made to improve contaminant sorption, aligning well with the principle goal of SDG 6 to obtain clean water and sanitation (Abdul et al, 2017; Heo et al, 2019; Meili et al, 2019).…”

Engineered biochars are promising candidates in a wide range of environmental applications, including soil fertility improvement, contaminant immobilization, wastewater treatment and in situ carbon sequestration. This review provides a systematic classification of these novel biochar composites and identifies the promising future trends in composite research and application. It is proposed that metals, minerals, layered double hydroxides, carbonaceous nanomaterials and microorganisms enhance the performances of biochars via distinct mechanisms. In this review, four novel trends are identified and assessed critically. Firstly, facile synthesis methods, in particular ball milling and co‐pyrolysis, have emerged as popular composite fabrication strategies that are suitable for large‐scale applications. Secondly, biochar modification with green materials, such as natural clay minerals and microorganisms, align well with the on‐going green and sustainable remediation (GSR) movement. Furthermore, new applications in soil health improvement and climate change mitigation support the realization of United Nation's Sustainable Development Goals (SDGs). Finally, the importance of field studies is getting more attention, since evidence of field success is critically needed before large‐scale applications.
