6. Abstract:

Global energy consumption is projected to triple by the end of the 21st century relative to the present rate due to population and economic growth.  The energy demand can be met from fossil fuels such as petroleum and coal.  However, doing so would triple the level of atmospheric CO2 by the end of the century.  Such a dramatic increase of CO2 concentration in the atmosphere is likely to perturb global ecosystems on an unprecedented scale.  Therefore, it is crucial for the global community to move quickly toward carbon-neutral energy sources.  Solar energy is by far the largest exploitable resource of renewable energy.  The amount of solar energy incident on the earth in one hour is enough to power our planet for one year.  The best way to harvest solar energy is to build artificial photosynthetic devices (APDs) that use sunlight to split water and combine the liberated hydrogen with CO2 to form energy-rich liquid hydrocarbons.  Such liquid fuels are easy to transport and store, and, importantly, allow us to continue using existing infrastructure.  Building large-scale, efficient, low-capital APDs is a very challenging task.  It is crucial to discover earth-abundant, inexpensive, efficient anodic and cathodic electrocatalysts.  In this seminar, I will talk about our strategies and designs of novel electrocatalysts for the anodic oxygen evolution reaction and for cathodic CO2 reduction reaction.
