Induced Electrodeposition of Molybdenum and Tungsten Alloys
Professor Elizabeth J. Podlaha of Northeastern University is supported by the Chemical Catalysis Program in the Division of Chemistry to study the mechanisms of induced electrochemical codeposition of molybdenum and tungsten alloys from aqueous solutions, and to use these alloys in a nanowire architecture to catalyze electrolytic hydrogen production. The alloys will be reduced under photoelectrochemical excitation and the composition of the resulting deposit will be characterized. The mechanisms will be examined by impedance techniques, including intensity-modulated photocurrent and intensity-modulated photovoltage spectroscopy, and the structure of the deposit will be characterized by surface analytical methodologies. A mathematical model to predict deposit composition will be developed.
Northeastern University’s College of Engineering is home to numerous federally-funded research centers and an array of leading-edge projects and initiatives that advance discovery and new knowledge in health, sustainability, and security.
