“…The second stage mostly came from the decomposition of protein and some carbohydrate and lipids. 18 We can see from Figure 1 that the TG and DTG curves showed almost the same trend at four heating rates, and there was no significant difference in pyrolysis residues, indicating that the degradation behavior was identical. Moreover, as the heating rate increased, the peaks of the DTG curve became sharper, suggesting that higher heating rates significantly improved the mass-loss rates.…”

Every summer, algal bloom occurs in Chaohu Lake, causing the death of large numbers of aquatic animals, water pollution, and environmental pollution. Although Chaohu algae (CHA) is a pollutant, it represents a possible renewable energy source. This work aims to analyze the pyrolysis kinetics of CHA for the production of biochar and show the potential of the biochar for electrochemical applications. The thermal degradation features of CHA were studied using thermogravimetric and TG-FTIR analysis. Meanwhile, Flynn-Wall-Ozawa and Kissinger-Akahira-Sunose methods were applied for the evaluation of kinetic parameters. CHA was then pyrolyzed using the microwave-assisted method to obtain biochar. The biochar structure and components were characterized by SEM, XRD, and Raman spectra. And the electrocatalytic performance was measured via cyclic voltammetry (CV) test with the biochar-modified electrode. It was found that the volatile products mainly contained water, methane, carboxylic acid, ketones, aldehyde groups, and NH 3 indicated by the real-time online FTIR spectra. And the comprehensive characterization showed that the CHA-derived biochar had unique properties as a superior functionalizing material for electrochemical applications. To sum up, we innovatively proposed to apply the biochar from the pyrolysis of CHA as an electrode functionalizing material and further evaluated the detection performance of the modified electrode.

Recently, the glycolipids biosurfactant materials have widely been utilized for many industrial applications due to their feasible surface activity, biodegradable as well as eco-friendly nature. Even though many of the earlier studies have been reported on such kind of surfactants, in this study we focused on porous rocks-like Fe 2 O 3 /C composites, which were magnificently synthesized from a novel tropical fruit biomass, using a glycolipid biosurfactant with high specific surface area of about 466.9 m 2 /g via a biofunctional single-step thermochemical method. They could be applied as an adsorbent to adsorb the pharmaceutical pollutants mainly, DCF from aqueous solution. Moreover, the highest adsorption capacity for DCF could be achieved, which is of about 77.51 mg/g. Furthermore, as-prepared glycolipid functionalized Fe 2 O 3 /C composites were used as electrode materials for high-performance supercapacitors.Galvanostatic charge-discharge results showed that the Fe 2 O 3 /C modified electrode possesses a specific capacitance of about 374 F/g with a current density of 0.2 A/g and it has retained 84% of capacitance, even after 3000 cycles.
