摘要：My major research goals are to (i) design and synthesize new non-molecular inorganic materials for use in condensed matter physics research, (ii) explore new ceramic inorganic oxygen/hydrogen membranes for energy applications. First, the MX2 Layered transition-metal dichalcogenides (TMDCs, M = Mo, W, V, Nb, Ta, Ti, Zr, Hf, and Re, and X = Se, S or Te), have long been of interest due to the rich electronic properties that emerge due to their low dimensionality. 1-4 One part of my work has been focused on search for new TMDC superconductors by chemical pressure via a solid state method. On the other hand, severe global warming change induced by the emission of a major greenhouse gas, CO2, which mainly produced by the traditional power generation system, demanding innovative strategies to reduce the CO2 emission. An integration of such oxygen transport membranes (OTMs) into oxy-fuel power plants, can facilitate CO2 capture and sequestration strategies to reduce CO2 emission, and enable thermal integration and energy savings to realize the process with the highest efficiency. My goal is to design and synthesis of new CO2-stable membranes materials by one pot method targeted for CO2 capture.
