(662a) Metal-Oxide Nanoarray based Catalysts for Water Electrolysis and CO2 conversion at High Efficiency and Low Cost

Three-dimensional (3-D) assemblies of nanomaterials into applicable platforms or devices demand to meet the practical requirements in cost-effectiveness, structure sophistication, multi-function enabling, green and robust operations. Such integration process and product enabling involve dissimilar nano-building-blocks such as particles, wires, and films made of metals, ceramics, or polymers. In this talk, I will review our decade-long research effort in the assemblies and integrations of various ceramics and metals in the forms of nanostructure arrays (nanoarrays) onto different macroscale surfaces as function-carrying reactors and devices. Departing from automotive catalytic converters, sensors, water electrolysis, to CO₂-methanol conversion, a unique green process and product engineering pathway is being laid out with nanomaterial design, function-enabling, manufacturing capability, system integratability, and economic affordability as the underlying bases. Modular, multifunctional, and scalable nanoarray devices and systems are being designed and enabled for conversion, monitoring, production, and redistribution of fuels and chemicals such as carbon dioxide, hydrogen, and methanol.
