“…Previous study found that DOM released from biochar prepared at 600 °C was more aromatic and of larger average molecular weight than that obtained at 350 °C (Jamieson et al, 2014). In addition, biochar DOM obtained at the low temperature had more carboxyl groups (Zhang et al, 2019).…”

“…The component 2 (C2) exhibited a peak at 360/425 nm (Ex/Em), was assigned to a fulvic-like substance with the larger molecular size than C1 (Li et al, 2017). The component 3 (C3), detected at Ex/Em of 365/480 nm, was categorized as UVA humic-like substance (Zhang et al, 2019). In addition, C3 was characterized as "reduced quinones" with greater aromaticity than C1 and C2 (Cory and McKnight, 2005).…”

“…For example, high temperature drives formation of phenolic hydroxyls, by braking the methoxy, and orthooxybenzyl alcohol dehydrated to form methyl quinone (Brebu et al, 2013;Zhang et al, 2019). The results of hydrochar is the opposite, which might be attributed to the differentiation of carbonization method governing the formation of the aromatic component.…”

“…This is because of its heterogeneous components [ 152 ]. The electron transfer capability for Cr (VI) reduction of biochar is exhibited by a high content of aromatic moieties and quinone [ 153 ]. In a study, it was observed that walnut-derived biochar was capable of potassium chromate oxidation [ 154 ].…”

Bioengineered biochar as smart candidate for resource recovery toward circular bio-economy: a review

et al. 2021

Biochar’s ability to mediate and facilitate microbial contamination degradation, as well as its carbon-sequestration potential, has sparked interest in recent years. The scope, possible advantages (economic and environmental), and future views are all evaluated in this review. We go over the many designed processes that are taking place and show why it is critical to look into biochar production for resource recovery and the role of bioengineered biochar in waste recycling. We concentrate on current breakthroughs in the fields of engineered biochar application techniques to systematically and sustainable technology. As a result, this paper describes the use of biomass for biochar production using various methods, as well as its use as an effective inclusion material to increase performance. The impact of biochar amendments on microbial colonisation, direct interspecies electron transfer, organic load minimization, and buffering maintenance is explored in detail. The majority of organic and inorganic (heavy metals) contaminants in the environment today are caused by human activities, such as mining and the use of chemical fertilizers and pesticides, which can be treated sustainably by using engineered biochar to promote the establishment of a sustainable engineered process by inducing the circular bioeconomy.

“…This largely depended on the properties of BC, which are affected by precursor feedstock and pyrolysis temperature [14]. A temperature of greater than approximately 700°C is usually needed to obtain BC/ZVI composites [15]. The BC prepared at this temperature is characterized by good conductivity, which favor electron transfer and thus passivation of ZVI.…”

There is a need to prepare a high-efficient sorbent to remove the recalcitrant tetracycline (TC) in wastewater. Herein, biochar-supported zerovalent iron (BC/ZVI) was fabricated in nitrogen ambience via one-step co-pyrolysis of hematite and pinewood. X-ray diffractometer pattern indicated pinewood catalyzed conversion of hematite to ZVI, which was otherwise transformed to FeO, Fe 3 O 4 and ZVI without biomass. Batch sorption results indicated that TC removal capacities at pH 5 were 8.02, 177.70 and 301.39 mg g −1 by BC, ZVI and BC/ZVI, respectively. Overall, BC/ZVI showed excellent TC removal capacity through the complexation with Fe ions, surface adsorption and degradation. Thus, the agricultural and industrial wastes were converted via a one-step co-pyrolysis to a value-added product for highly efficient removal of TC in wastewater.
