Our research endeavors in the area of Electrochemical Surface Science are rooted to the premise that superior technology in electrochemistry emanates from superior science; that major advances in technologies which capitalize on the interplay between chemistry and electricity can be gained from an atomic-level understanding of processes which occur at the electrode-solution interface.
Our experimental strategies rely on the integration of traditional electrochemical techniques with modern surface spectroscopic methods. Techniques available in the Electrochemical Surface Science Laboratory include: scanning tunneling microscopy, atomic-force microscopy, low energy electron diffraction, Auger electron spectroscopy, X-ray photoelectron spectroscopy, high resolution electron energy loss spectroscopy, Fourier transform infrared spectroscopy, thermal desorption mass spectrometry, and thin-layer electrochemistry. We have also availed of the National Synchrotron Light Source at Brookhaven National Laboratory.
Projects currently under investigation in our Laboratory are: the surface science of electrocatalysis; electrochemistry of nanostructured interfaces; electrode-surface coordination and organometallic chemistry; metal-hydrides for hydrogen storage; mixed-metal electrocatalysts for fuel cell applications; and green electroanalytical chemistry. We are also active in the following collaborative studies with other research groups: electrocatalysis at active-site analogues of hydrogenase enzymes; differential electrochemical mass spectrometry; interfacial chemistry of the Grignard reaction; electrochemical applications in waste-water treatment; thin-film growth at electrode surfaces; and Ni-metal hydride batteries.
These studies find relevance in several technological areas such as: renewable energy sources, heterogeneous catalysis, corrosion inhibition, materials science, microelectronics, electroanalysis and sensors.
