Cathodic Catalyst

Much effort has been devoted to the synthesis of novel nanostructured MnO2materials because of their unique properties and potential applications as cathode catalyst in Microbial fuel cell. Hybrid MnO2nanostructures were fabricated by a simple hydrothermal method in this study. Their crystal structures, morphology, and electrochemical characters were carried out by FESEM, N2-adsorption-desorption, and CV, indicating that the hydrothermally synthesized MnO2(HSM) was structured by nanorods of high aspect ratio and multivalve nanoflowers and more positive than the naturally synthesized MnO2(NSM), accompanied by a noticeable increase in oxygen reduction peak current. When the HSM was employed as the cathode catalyst in air-cathode MFC which fed with leachate, a maximum power density of 119.07 mW/m2was delivered, 64.68% higher than that with the NSM as cathode catalyst. Furthermore, the HSM via a 4-e pathway, but the NSM via a 2-e pathway in alkaline solution, and as 4-e pathway is a more efficient oxygen reduction reaction, the HSM was more positive than NSM. Our study provides useful information on facile preparation of cost-effective cathodic catalyst in air-cathode MFC for wastewater treatment.

This study shows the effectiveness of titanium dioxide (TiO₂) on a floating microbial fuel cell (FMFC). In the experiment, when a UV cutoff filter attached halogen lamp was used, the power density of the FMFC using pristine TiO₂ (P25) and the FMFC using TiO₂ sintered at 650 °C were was 2.11mW/m2 and 10.44 mW/m2 respectively. Next, when measured without UV cutoff filter, pristine TiO₂ type FMFC and 650°C sintered TiO₂ type FMFC recorded 2.93 mW/m2 and 11.93 mW/m2 respectively. From this result, it was confirmed that the power density was improved up to five times when the UV cutoff filter was used and four times when it was not used. According to the results of X-ray Diffraction (XRD), 650°C sintered TiO₂ is composed of more rutile phase than pristine TiO₂.
