“…The maximum tensile strength of ca.43 MPa was observed at a biochar concentration of 10%, while the tensile strength decreased by 41% when the concentration was increased to 15%. Similar to the current study, Richard et al observed a decrease in tensile strength with increasing biochar concentration when rice husk biochar was introduced into the polyester matrix 24 . In comparison to the neat vinyl ester, the biochar‐added composite has a very high axial strength.…”

Biomass and other biogenic wastes can be used in polymeric materials, allowing for effective waste utilization. Thus, these materials can be converted into biochar and used in composite fabrication. Biochar was used in the current study to improve the mechanical and thermal properties of vinyl ester‐based composites. Waste cashew nut shells were converted into biochar via a slow pyrolysis method. Biochar was added at three different levels (5, 10 and 15 wt.%). Composite with 10 wt.% biochar showed ca.72% and ca.54% higher tensile strength and hardness than the neat vinyl ester. The composite containing 15 wt.% biochar showed the highest impact and flexural strength of ca.47 MPa and ca.13 kJ/m2 respectively. The thermo‐gravimetric study showed that the composites with 15 wt.% added biochar performed better than the others, with a yield percentage of ca.45%. This study provides a summary of biochar applications and highlights the advantages of biomass wastes with respect to energy and environmental sustainability for the production of strong and thermally stable composites.

“…Fourier transform infrared spectroscopy analysis: The infrared spectrum analysis results of SRBC500 prepared at different pyrolysis times are shown in Figure 3. Fourier transform infrared spectroscopy (FTIR) is one of the effective means to measure the functional groups in biochar (Cole et al 2019). Pyrolysis time has an important influence on the structure and properties of biochar, which is mainly due to the different carbonization degrees of Spirulina residue, thus changing the functional groups on the surface of biochar.…”

In this work, Spirulina residue was used as the raw material to prepare different biochars by changing the pyrolysis time. Moreover, the obtained products were characterized by scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction energy spectra. This experiment used the batch adsorption method to study the adsorption effect of pH, dosage, and pyrolysis time on methyl orange. The adsorption of methyl orange onto Spirulina residue biochar (SRBC) were fitted with the Langmuir isotherm model and pseudo-second-order kinetics. The results showed that the surface functional groups of SRBC obtained by dry pyrolysis were abundant, and could effectively adsorb methyl orange dye in an aqueous solution. The sample prepared at 500 °C for 5 h had the best adsorption effect on methyl orange. The change of pyrolysis time will affect the physicochemical properties of biochar from Spirulina residue, thereby affecting its adsorption effect on methyl orange dye. The analysis showed that the chemical adsorption of SRBC on methyl orange might be the primary way of dye removal. The results can provide a reference for preparing biochar from algae residue and biochar application in the removal of dye wastewater.

“…The bands around 1,490 cm −1 represented the stretching vibration of aromatic CO and benzene ring CC, and the band at 750 cm −1 was assigned to the bending vibration of CH and OH. [ 43 ] The absorption peaks at 1,100–900 and 553 cm −1 were ascribed to the FeO stretch vibration. [ 3,38 ] These characteristic peaks can be clearly observed on BC‐nPd/Fe, indicating that nPd/Fe was successfully loaded on the BC.…”

In the present study, peanut shell, a green waste raw material, was used to prepare biochar (BC) and to obtain BC‐supported nano‐palladium/iron (BC‐nPd/Fe) composites for removing 2,4‐dichlorophenoxyacetic acid (2,4‐D) from water. Characterization analysis demonstrated that nPd/Fe particles were well dispersed on the BC surface with weakened magnetic properties. The average particle diameter and specific surface area of nPd/Fe were 101.3 nm and 6.7 m2 g−1, whereas the corresponding values of the BC‐nPd/Fe materials were 88.8 nm and 14.8 m2 g−1, respectively. Several factors were found to influence the dechlorination of 2,4‐D, including the weight ratio of BC to Fe, Pd loading ratio, initial solution pH, 2,4‐D concentration, and reaction temperature. Dechlorination results indicated that the 2,4‐D removal and phenoxyacetic acid (PA) generation rates were 44.1% and 20.1%, respectively, in the nPd/Fe system, and 100.0% and 92.1%, respectively, in the BC‐nPd/Fe system. The dechlorination of 2,4‐D was well described by the pseudo‐first‐order kinetic model (R2 > 0.97), and the observed rate constants kobs were 0.0042 min (nPd/Fe) and 0.0578 min (BC‐nPd/Fe), respectively. The reaction mechanism indicated that the dechlorination hydrogenation was the main process to remove 2,4‐D from water in the BC‐nPd/Fe system. In addition, BC inhibited the formation of a passivation layer on the particle surface during the reaction, thus maintaining the high reactivity of BC‐nPd/Fe. The easy preparation technique, high 2,4‐D dechlorination capacity, and mild reaction conditions suggest that BC‐nPd/Fe may be a promising alternative composite to remove 2,4‐D from water.
