Dr. Ramendra Sundar Dey


Dey's laboratory for Electrochemistry of NanoMaterials (DENanoMat) group research interest is focused on nanocarbon-based hybrid materials for state-of-the-art energy storage and conversion system for renewable energy generation. We are in progress in developing a hybrid supercapacitor with battery or biofuel cells for clean and self-sustainable energy storage devices, paper-based biofuel cell and electrochemical study of nanoporous materials. Electrochemical fixation of CO2 and N2, and metal-air battery is our major research interest. We are also interested in developing low-cost biosensing devices.

Research Highlights

  • Transition-metal atoms and/or heteroatom-doped carbon nanostructures is a crucial alternative to find a nonprecious metal catalyst for electrocatalytic oxygen reduction reaction (ORR). Dr. Dey's group herein, for the first time demonstrated the formation of binary (Fe–Mn) active sites in hierarchically porous nanostructure composed of Fe, Mn, and N-doped fish gill derived carbon. The catalyst shows remarkable ORR performance with onset potential (Eonset) of 1.03 V and half-wave potential (E1/2) of 0.89 V, slightly better than commercial Pt/C (Eonset = 1.01 V, E1/2 = 0.88 V) in alkaline medium (pH > 13), which is attributed to the synergistic effect of Fe–Mn dual metal center as evidenced from X-ray absorption spectroscopic study. The homemade rechargeable Zn–air battery with the catalyst is outperforming Pt/C with almost stable charge–discharge voltage plateaus at high current density. The present strategy enriches a route to synthesize low-cost bioinspired electrocatalyst that is comparable to/better than any nonprecious-metal catalysts as well as commercial Pt/C.

  • Dr. Ramendra S. Dey and his research team have recently shown that interconnected porous graphene plays a crucial role as supercapacitive material as well as a current collector in developing metal free microsupercapacitor (MSC) because of its unique structure and superior conductivity. Electrochemical reduction followed by use of a laser irradiation method shows advances for the fabrication of the conductive graphene-based robust device. The laser irradiation method is capable of healing the defects with fused interconnected sheets, as a result, high conductivity and improved crystallinity of the laser irradiated graphene (LIG) sample is achieved. The LIG film on a flexible substrate was patterned with the aim to develop an on-chip flexible MSC, which offers a large cell voltage of 10.8 V and 100% retention of the initial capacitance after 100 000 continuous cycles. The array of LIG-MSC was integrated with a commercial solar cell module for hybrid energy harvesting and as a storage device. This study provides an effective strategy to build a metal-free supercapacitor with exceptional cycle life and facilitates progress towards self-sustainable energy in the future.
