“…Besides, Figure 1 (a) shows that when the temperature of MBN3 increased from 400 to 500°C, the removal also increased from 87.4 to 88.6%. Beyond 500°C the removal began to dwindle with the increment of temperature, probably due to insufficient pore structures and active sites at high pyrolytic temperatures (Peng et al, 2019). In particular, over-gasification would occur at 700°C, thereby decreasing the porosity and surface area.…”

The sugarcane bagasse (SCB) was a precursor in synthesising magnetic biochar using a modified single-stage electric muffle furnace to remove Cd 2+ ions in industrial wastewater. Nickel (II) oxide (NiO 2 ) was added to boost the efficiency of yield and the removal of heavy metals. The magnetic biochar (MBN3) was optimally synthesised at 500 o C for 30 minutes with an IR of 0.4 to evaluate its performance in adsorption capability. Analyses of Field Emission Scanning Electronic Microscopy indicated that pores in the magnetic biochar enlarged after the impregnation and decomposition with an average diameter of 3.2 nm (MBN3) and surface area of 63.5 m 2 g -1 . The highest removal for Cd 2+ onto MBN3 was 87.6%, reaching pH 6.0 and an agitation speed of 125 rpm for 60 minutes. The maximum adsorption capacity (q m ) for the adsorption of Cd 2+ onto MBN3 was 47.9 mgg -1 . The adsorbent followed the pseudo-second-order kinetic model and the Langmuir-Freundlich isotherm model with R 2 = 0.9853 (Langmuir) and R 2 = 0.9538 (Freundlich), suggesting that the surface of MBN3 might be heterogeneous with different classes of active sites, heavy metals were adsorbed on some classes of active sites only, rather than on all active sites.

“…With the increase in temperature (250-400 ℃), the rapid weight loss was due to the six-membered ring opening, glycosidic bond breakage and oxygen-containing double bond rearrangement in cellulose and hemicellulose molecules. The shoulder peak at low temperature (~ 250 ℃) belonged to the degradation of hemicellulose, while the peak at high temperature (~ 400 ℃) was recognized as the degradation of cellulose (Peng et al 2019). Different from cellulose and hemicellulose, the decomposition process of lignin was very slow and complicated due to their native heterogeneous structure, with continuous weight loss from the initial to the end and no peak observed (Leng et al 2022).…”

Developing effective electrodes with commercial-level active mass-loading (> 10 mg cm−2) is vital for the practical application of supercapacitors. However, high active mass-loading usually requires thick active mass layer, which severely hinders the ion/electron transport and results in poor capacitive performance. Herein, a self-standing biochar electrode with active mass-loading of ca. 40 mg cm−2 and thickness of 800 µm has been developed from basswood. The basswood was treated with formamide to incorporate N/O in the carbon structure, followed by mild KOH activation to ameliorate the pore size and introduce more O species in the carbon matrix. The as-prepared carbon monoliths possess well conductive carbon skeleton, abundant N/O dopant and 3D porous structure, which are favorable for the ion/electron transport and promoting capacitance performance. The self-standing carbon electrode not only exhibits the maximum areal/mass/volumetric specific capacitance of 5037.5 mF cm−2/172.5 F g−1/63.0 F cm−3 at 2 mA cm−2 (0.05 A g−1), but also displays excellent rate performance with 76% capacitance retention at 500 mA cm−2 (12.5 A g−1) in a symmetric supercapacitor, surpassing the state-of-art biomass-based thick carbon electrode. The assembled model can power typical electron devices including a fan, a digital watch and a logo made up of 34 light-emitting diodes for a proper period, revealing its practical application potential. This study not only puts forward a commercial-level high active mass-loading electrode from biomass for supercapacitor, but also bridges the gap between the experimental research and practical application.
