Research Area: Enhancing the performance of microbial fuel cell by zeolite mediated anode and Ag-Pt nano alloy catalysed cathode.

Objectives:

  • To fabricate zeolite mediated anode supported on graphene oxide (GO) to enhance bio-catalytic activity of anodophile in microbial fuel cells (MFCs).
  • To synthesize and characterize silver-platinum (Ag-Pt) nano-alloy dispersed on N-doped graphene nano-sheet as cathode catalyst for enhancing oxygen reduction reaction (ORR) in MFC.
  • To enhance in situ bioremediation of sediment in sediment microbial fuel cell (SMFC) and subsequent power recovery using graphene oxide-zeolite modified carbon felt/stainless steel wire mesh anode.

Findings of the study:

  • SEM, XRD and Raman spectroscopy analyses confirmed the doping of GO-Zeolite composite and GO on the respective carbon felt anodes.
  • Zeolite-GO composite doped carbon felt was found promising to be used as anode material in MFC for high coulombic recovery and superior performance.
  • Zeolite as a mediator in MFC increased the CE by 2.6-folds and power density by 3.6-folds.
  • N-doped graphene with Ag/Pt/Ag-Pt cathode catalysts were synthesised by one pot hydrothermal process and were characterised by TEM, XRD, Raman spectroscopy, Nano Auger Spectroscopy. N-doped graphene with Ag-Pt was found to be a promising cathode catalyst to enhance ORR of MFCs.

Research area and interest: Constructed wetland microbial fuel cells

  1. Wastewater treatment
  2. Bioenergy
  3. Aquaculture
  4. Hydroponic system

Findings of the study:

Upflow hydroponic constructed wetland microbial fuel cell (UHCWMFC) for wastewater treatment and recovery of bioelectricity.

The effect of incorporating clayware separator on the performance of UHCWMFC was evaluated in terms of organic matter removal efficiency and power generarion by comparing a system with clayware separator (R1) to another with no separator (R2). Under continuous mode of operation and inlet COD of 500 mg.L-1 at a liquid retention time of 12.8 h, the R1 and R2 exhibited  86.6 ± 5.29 % and 90.7 ± 4.7 %,COD removal efficiencies respectively. In terms of power generation, R1 produced 1.58 and 1.57 times higher maximum sustainable power density (SPD)and normalized energy recovery (NER) respectively than those of R2 ( 80.0 mW.m-3, 36.9 Wh.m-3).

 This indicated that incorporating clayware separator helped in maintaining anaerobic anodic environment and facilitated proton transfer, which eventually enhanced the power density and energy recovery.

Research area and Interest: Application of low cost catalysts to improve the desalination efficiency in Microbial desalination cells (MDC).

Findings of the study:

The study on Microbial desalination cell with the use of carbon supported Ag-SnO2 on cathode surface improved the oxygen reduction kinetics and desalination efficiency as well. The maximum power density obtained with the use of carbon supported Ag-SnO2 as cathode catalyst is 62.3mW/m2 which is a 1.67 fold increase than the MDC with no catalyst (37.5mW/m2). The maximum desalination efficiency obtained is of 75.7% enabling MDC as prior treatment to Reverse Osmosis along with the waste water treatment as well.
