Research Interests

The research activity in Prof. Mukerjee’s group is an interdisciplinary approach encompassing the areas of solid state chemistry, spectroscopy, and electrochemistry of electrode materials for electrochemical energy conversion and storage. The current focus is targeted towards technologies for proton exchange membrane (PEM) fuel cells and for batteries, these encompass electrocatalysis of oxygen reduction, CO tolerance and methanol oxidation reactions, elevated temperature polymer electrolyte membranes, advanced rechargeable batteries with nickel metal hydrides and lithium insertion electrodes for lithium ion and lithium polymer batteries.

The emphasis is to develop new novel electrode materials for both electrocatalysis as well as intercalation and to investigate mechanisms of electrode processes using advanced synchrotron based in situ techniques. The synchrotron based spectroscopic technique of X-ray absorption spectroscopy (XAS) offers unique insights into electrode processes by providing simultaneous electronic and structural information of the electrode materials under actual in situ cell operating conditions. XAS with its element specificity and ability to probe changes in the chemical (oxidation state, corrosion etc.) and the short-range atomic order is especially relevant due to applicability to complex nano-crystalline and amorphous systems. This electrode substrate information is complimented by use of synchrotron based in situ X-ray diffraction (XRD) and IR spectroscopy, both possessing advantages of higher resolution and, in the case of IR spectroscopy, the ability to measure in the far infrared, thus extending the scope and quality of these measurements.

Where to put all the energy

North­eastern Uni­ver­sity con­vened experts from industry, gov­ern­ment, and acad­emia last week to dis­cuss advance­ments in next-​​generation energy storage and bat­tery tech­nolo­gies as well as their com­mer­cial via­bility, which could have a major impact in addressing global chal­lenges in areas such as energy con­sump­tion, mate­rials short­ages, and cli­mate change.

The future’s most pressing energy questions

Top researchers, entre­pre­neurs, scholars, and pol­i­cy­makers from Mass­a­chu­setts and Switzer­land con­vened at North­eastern Uni­ver­sity on Friday for an energy summit, where par­tic­i­pants dis­cussed inno­va­tions and strate­gies to address cli­mate change and a range of other global energy challenges.

Northeastern to host Renewable Energy Storage Symposium

Alter­na­tive energy sources are often touted as the solu­tion to the waning global supply of oil and mounting evi­dence of carbon-​​induced cli­mate change.
