NICOP - Controlled Synthesis of Copper Oxide-Metal-Organic Framework-based Hybrid Nanoparticles for Nano-energetics and Nanocatalysis
Abstract
Copper oxides (CuxO), especially in the form of nanoparticle (NP), are highly attractive for the production in power and energy. CuxO-based NP can be used as catalysts or as a new class of additives to the fuels to improve the efficiency in energy release. Besides, metal~ organic frameworks (MOFs) with exceptionally high surface area and chemically tunable structures are suitable for a variety of energy applications. Our objective is to fabricate functional CuxO-MOF hybrid nanoparticles using gas-phase direct assembly. Differential mobility analyzer (DMA), transmission electron microscopy (TEM), and scanning electron microscopy (SEM) will be employed orthogonally as in-situ and ex-situ analytical methods for the nanohybrids. The novelty of the proposed method includes a real-time temperature-programmed reduction system will be developed for real-time monitoring particle size, oxidation states and the corresponding catalytic activity over a variety of fuels in forms of gas, liquid, and solid. In addition, we will develop a new strategy of differential temperature analysis on the synthesized nanohybrids directly in the form of aerosol. Based on the in-situ measurement of physical size versus the heating temperature, we can derive the critical information regarding to thermal stability of nanohybrids during the reaction. Through the development of synthesis and material characterization, particle size, morphology, surface state, and chemical composition can be adjusted via employing a gas- phase reaction cell. The reducibility and the corresponding catalytic activity over various types of gas and colloidal fuels will be analyzed by prototype reaction systems established in this study. This is the first time to study CuxO-MOF for applications in nano-energetics and nano-catalysis. The method combines the development of material synthesis with ability in the characterization of material properties (size, morphology, composition, surface state) and the performance systematically. This is also the first time that the MOF- based nanohybrid colloids can be real-time characterized, providing the opportunity of controlled assembly of MOF to form other types of hybrid nanostrucuture for a variety of applications in nano-energetics and nanocatalysis.
