“…The guest phases provided high adsorption and made the materials susceptible to rapid desorption by magnetic induction-features that are impossible to achieve with traditional foams. Similarly, carbon-Fe-nanoparticle-composite Guefoams with activated carbon guest phases were developed for the same purpose [4]. While the guest phases significantly increased the specific surface area and gas adsorption capacity, the iron nanoparticles embedded in the ceramic matrix conferred a high magneto-inductive capacity, enabling the ultrafast heating and rapid desorption of the adsorbed species.…”

To enhance their corrosion protection, Guefoams were coated with RGO using both potentiostatic and potentiodynamic methods. The potentiodynamic method produced the thickest RGO coating and the lowest Cl, O, and Al content, as observed using FESEM and EDX. The Guefoams were exposed to a 3.5% NaCl solution and steam. The polarization resistance was examined, electrochemical impedance spectroscopy was performed, and polarization curves were constructed to monitor the corrosion process. After 28 days, the Al concentrations in the solutions were measured, and were found to be 145 mg/L (bare Guefoam), 70 mg/L (RGO-coated, potentiostatic), and 35 mg/L (RGO-coated, potentiodynamic). The potentiodynamic RGO coating also showed the best corrosion protection values.

“…Converting asphalt into a high-value-added product can provide sustainability and economic benefits. , Asphalt is a low-cost and high-carbon-yield precursor, asphalt-derived carbon (ADC) has been used in adsorption, − and electrochemical energy storage and conversion; , however, little effort has been devoted to developing the use of ADC in the field of EBFCs. In our previous work, ADC was synthesized via thermal annealing of a mixture containing Fe 2 O 3 and asphalt and was used as an electrode material to coimmobilize enzymes and mediators in the application of self-charged glucose/air EBFCs via the pseudocapacitance behavior of the redox mediators .…”

The electrode materials play extremely important roles in building the interfacial electron communications between the active sites of enzymes and the electrode surface, which significantly affect the performance of an enzymatic biofuel cell (EBFC). Herein, defective porous carbon is rationally designed and prepared using asphalt as the low-cost and high-carbon-yield precursor via a facile catalytic pyrolysis and NH 3 -etching process. The obtained defective asphalt-derived carbon (D-ADC) is utilized as the electrode material to immobilize enzymes and mediators in EBFC applications. It is found that the morphology and structure of ADC can be regulated by the catalytic pyrolysis and NH 3etching processes, which greatly increase the electroactive sites and specific surface area, thus enhancing the catalytic reaction kinetics. Specifically, the fabricated EBFC using D-ADC as the electrode material exhibits an open circuit voltage of 0.58 V and delivers a maximum output power density of 0.32 mW cm −2 with a short circuit current density of 1.12 mA cm −2 , comparable to those using conventional graphene and carbon nanotubes. This work offers guidance for the design of functional carbon materials in the application of EBFCs, which has the potential to improve the sustainability and economic efficiency of waste asphalt.
