Researchers from Singapore National University Report Details of New Studies and Findings in the Area of Hydrology (Different types of carbon nanotube-based anodes to improve microbial fuel cell performance)

By a News Reporter-Staff News Editor at Energy Weekly News -- Researchers detail new data in Hydrology. According to news reporting from Singapore, Singapore, by VerticalNews journalists, research stated, "The microbial fuel cell (MFC) is an innovative technology for producing electricity directly from biodegradable organic matter using bacteria. Among all the influenceable factors, anode materials play a crucial role in electricity generation."

The news correspondents obtained a quote from the research from Singapore National University, "Recently, carbon nanotubes (CNTs) have exhibited promising properties as electrode material due to their unique structural, and physical and chemical properties. In this study, the impacts of CNT types in CNT-based anodes were investigated to determine their effect on both efficiency of wastewater treatment and power generation. The CNTs, namely single-walled CNT with carboxyl group (SWCNT), multi-walled CNT with carboxyl group (MWCNT-COOH) and multi-walled CNT with hydroxyl group (MWCNT-OH) were used to fabricate CNT-based anodes by a filtration method. Overall, MWCNTs provided better results than SWCNTs, especially in the presence of the -OH groups. The highest power and treatment efficiencies in MFC were achieved with an anode made of MWCNT-OH filtered on Poreflon membrane; the open circuit voltage attained was 0.75 V and the maximum power density averaged 167 mW/m(2), which was 130% higher than that obtained with plain carbon cloth."

According to the news reporters, the research concluded: "In addition, MWCNT-OH is more cost-effective, further suggesting its potential to replace plain carbon cloth generally used for the MFC anode."
