Abstract:

Rapid depletion of non-renewable fossil resources is posing an imminent threat to the energy and supply of fine chemicals that are vital to the global economy. Currently, efforts are being undertaken at an accelerated pace to develop technologies that would help us deal with the disastrous consequences. We have been working in the areas of bio-mass conversion to renewable fuels/chemicals as well as the production of hydrogen through electrocatalytic splitting of water using non-noble metals. In both of these areas, there is a dire need to develop cost-effective materials to increase the efficiency of the processes.  For the biomass conversion we have designed and developed novel catalytic materials with the conversion efficiencies superior to those that currently exist. Likewise, we have also been exploring the use of anionically modified molybdenum oxides and phosphides for efficient splitting of water in both acidic and alkaline conditions. In addition, we have also examined the possibility of creating new energy resources by catalytically producing a new form of hydrogen wherein the sole electron is stabilized in fractional quantum states. The presentation will summarize our findings and the opportunities for exploring inorganic materials for the production of value added chemicals and fuels.
