Overview

We continue to synthesize novel nanomaterials to address energy, environmental and health problems. In particular, our research themes center around the development of carbon-based materials, especially carbon nanofibers and carbon nanoparticles in the adsorption, and catalytic reaction applications including microbial fuel cells. The recent focus is on the synthesis and characterization of the adsorbents and metal catalysts for the removal of common atmospheric air pollutants such as CO2, NOx, and SOx by adsorption and/or catalytic oxidation and that of solutes such as arsenic, fluoride, heavy metals, and organics from wastewater by adsorption. We have also undertaken studies on the catalytic wet air oxidation of recalcitrant organics in water. On the theoretical side, a number of mathematical models based on lattice Boltzmann method have been developed to predict the breakthrough curves in the narrow tubular packed bed adsorber. The recent focus is on the development of lattice Boltzmann models for multi-phase flow.
