“…XRD spectra of raw orange peel and biochar samples B300, B500, and B700 are shown in Figure 4a–d. Figure 4a shows that the XRD spectra of raw orange peel exhibit an amorphous structure with a broad peak (Gonzalez‐Canche et al, 2021). The XRD spectra of biochars (Figure 4b–d) show a prominent amorphous peak at 24.31° corresponding to the [002] plane.…”

In the present study, orange peel biochar has been utilized as the adsorbent for the removal of phenol from contaminated water. The biochar was prepared by thermal activation process at three different temperature 300, 500 and 700°C and are defined as B300, B500, and B700 respectively. The synthesized biochar has been characterized using scanning electron microscopy (SEM), X‐ray diffraction (XRD), Fourier transformation infrared spectroscopy (FTIR), RAMAN spectroscopy, X‐ray photoelectron spectroscopy (XPS), and UV–Vis spectroscopy. SEM analysis revealed a highly irregular and porous structure for B700 as compared with others. The parameters such as initial phenol concentration, pH, adsorption dosage, and contact time were optimized, and the maximum adsorption efficiency and capacity of about 99.2% and 31.0 mg/g was achieved for B700 for phenol adsorption. The Branauer‐Emmett‐Teller (BET) surface area and Berrate–Joyner–Halenda (BJH) pore diameter obtained for B700 were about 67.5 m2/g and 3.8 nm. The adsorption of phenol onto the biochar followed Langmuir isotherm showing linear fit with R2 = 0.99, indicating monolayer adsorption. The kinetic data for adsorption is best fitted for pseudo‐second order. The thermodynamic parameters ΔG°, ΔH°, and ΔS° values obtained are negative, which means that the adsorption process is spontaneous and exothermic. The adsorption efficiency of phenol marginally declined from 99.2% to 50.12% after five consecutive reuse cycles. The study shows that the high‐temperature activation increased the porosity and number of active sites over the orange peel biochar for efficient adsorption of phenol. Practitioner Points Orange peel is thermally activated at 300, 500, and 700°C for structure modification. Orange peel biochars were characterized for its structure, morphology, functional groups, and adsorption behavior. High‐temperature activation improved the adsorption efficiency up to 99.21% due to high porosity.

“…XRD patterns of OPB and OPB/Fe3O4 are shown in Figure 2. An Extended signal between intervals of 2θ between 18°-25° was observed in the diffractograms of OPB, indicating the presence of amorphous carbon [31][32], the presence of a peak at 2θ = 43.25° confirm also the presence of certain degree of graphitic carbon [33][34]. In addition, the XRD patterns displayed other peaks at 2θ = 25°, 32°, 39°, and 48° which can be attributed to the presence of hydroxyapatite in the biochar (ICDD-PDF No 00-001-1008) [24].…”

In this work, biochar synthesized from orange peel modified with magnetite was used as an alternative magnetic adsorbent for dye removal. The magnetization of the synthesized biochar was done using the co-precipitation method. The obtained composite was characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), and Raman spectroscopy. The efficiency of magnetized biochar (OPB/Fe3O4) was studied in the process of removing crystal violet (CV) from an aqueous solution at different temperatures. The experimental data obtained for the kinetic studies were better fitted to the pseudo-second-order model, and the isotherms data were well fitted to the Langmuir model. The results showed that the adsorption capacity increases with increasing temperature, reaching 113 mg g-1 at 50 °C. Thermodynamic parameters (ΔG0, ΔH0, ΔS0) were also calculated; their values showed that the adsorption was spontaneous and endothermic. These results inspire us to use other similar materials to solve the problem of water and environmental pollution.

“…Compared with the conventional Pt/C based zinc air battery, biochar-based battery exhibited higher specific capacity (767 mAh/g Zn vs 684 mAh/g Zn) and peak power density (141 mW/cm 2 vs 126 mW/cm 2 ) (Qiao et al 2021). Furthermore, biochar has also been used as a pigment in solar absorber coatings owing to its possibility to reduce the reflectance of the material (Gonzalez-Canche et al 2021). It can also be utilized as a proxy to traditional Pt catalyst in dye solar cells (Tiihonen et al 2021).…”

Carbon neutrality by the mid-twenty-first century is a grand challenge requiring technological innovations. Biochar, a traditional soil amendment which has been used for fertility improvement and contaminant remediation, has revealed new vitality in this context. In this review we highlight the huge potential of biochar application in different fields to mitigate as high as 2.56 × 109 t CO2e total greenhouse gas (GHG) emissions per year, accounting for 5.0% of the global GHG emissions. Soil applications of biochar as either a controlled-release fertilizer or an immobilization agent offer improved soil health while simultaneously suppressing the emissions of CH4 and N2O. Non-soil applications of biochar also contribute to carbon neutrality in unique ways. Firstly, biochar application as a ruminant feed decreases CH4 emissions via physical sorption and enhanced activities of methanotrophs. Secondly, biochar can be used as a green catalyst for biorefinery. Besides, biochar as an additive to Portland cement and low impact development (LID) infrastructure lowers the carbon footprint and builds resilience to climate change. Furthermore, biochar can be used as novel batteries and supercapacitors for energy storage purposes. Finally, the high CO2 adsorption capacity makes it possible for biochar being used as a sorbent for carbon capture, utilization, and storage (CCUS). We advocate that future research should further explore the effectiveness of biochar systems for climate change mitigation in large scale applications, and assess the economic and social viability of local biochar systems to combat climate change.
