Silver–tungsten carbide nanohybrid for efficient electrocatalysis of oxygen reduction reaction in microbial fuel cell

Nickel oxide and carbon nanotube composite (NiO/CNT) as a novel cathode non-precious metal catalyst in microbial fuel cells

“…As known, carbon nanotubes (CNTs) are usually adopted as the catalyst support because of its high specific surface area, large energy conservation, high electrical conductivity and high chemical stability. The introductions of metal element or metallic oxide such as Fe (Li et al, 2012a(Li et al, , 2012b, Co (Sun, 2012), MnO 2 (Kumar et al, 2014), WC (Gong et al, 2013), Ru (Vazquez-Larios et al, 2012), andCoTMPP (Sun, 2012) to CNT or other carbon materials can dramatically enhance the performance of CNT or other carbon materials in terms of higher energy density, more distinct redox potential. Therefore, introducing NiO to CNT surface is expected to provide an opportunity to improve the ORR performance of the NiO.…”

Nickel Sulfide Nanoparticles Synthesized by Microwave-assisted Method as Promising Supercapacitor Electrodes: An Experimental and Computational Study

“…Among the various energy storage systems, supercapacitors also called electrochemical capacitors or ultracapacitors, have attracted tremendous attention because of their high power density, short charging/discharging time and superior cycle life [1][2][3]. Based on the use of electrode materials as well as the charge storage mechanisms, supercapacitors can be classified as electrical double-layer capacitors, Faradaic redox reaction pseudocapacitor.…”

Bioinspired Nanosucker Array for Enhancing Bioelectricity Generation in Microbial Fuel Cells

“…The cell voltage was then converted to power density according to the methods reported previously. [ 42 ] Polarization and power curves were obtained by recording stable peak cell voltage produced across different external resistances (50-10 000 Ω). The electrode potentials were recorded with respect to SCE reference.…”

“…The maximum power density of MFCs with nano-SA-CT electrode (SA-15#) was 58.3% higher than that with bare CT electrode, and also much higher than those reported in our prior works performed on the same testing system. [42][43][44] In addition, Figure 3 E shows the negligible change in cathode potential of the MFCs as opposed to the distinct variation in their anode potential, suggesting that the anode performance dominates the power production of MFCs.…”
