Inorganic & Materials Chemistry/Physical Chemistry

Since the beginning of the nineteenth centuries marked by a transition to new revolutionary manufacturing processes, ever-expanding human industrial activities have brought serious sustainability challenges especially in energy, water, environment and global health. One broad aspect of our research focus is chemistry of materials that enables solutions to these challenges. Our research group is particularly interested in new synthetic developments and interdisciplinary applications of nanostructured materials for renewable energy production, water purification and environmental remediation, by adopting green chemistry principles. Our fundamental research is geared to give an immediate and transformative impact to the society by providing creative materials solutions to the sustainability challenges. Our recent successes include development of a novel sol-gel synthetic method that produces nanoporous transparent conducting metal oxides (TCOs). Such materials have important applications in producing fuel or energy from sunlight. High-porosity alumina aerogels have been successfully produced for catalysis purpose through our new synthetic method that does not require cost-prohibitive supercritical drying process. One emerging material of our great interest is geopolymer, nanostructured amorphous aluminosilicates produced by an energy-efficient top-down chemical process at ambient temperatures. We have recently developed new inorganic-organic synthetic chemistry for synthesis of new nanoporous geopolymer materials which has significant implications in environmental remediation, water purification and catalysis. Further significant efforts are given to commercialization of our innovative materials synthesis methods and the materials products.
