Catalytic decomposition of NO2 over a copper-decorated metal–organic framework by non-thermal plasma
Abstract
<p>Efficient catalytic conversion of NO<sub>2</sub> to non-harmful species remains an important target for research. State-of-the-art deNO<sub>x</sub> processes are based upon ammonia (NH<sub>3</sub>)-assisted selective catalytic reduction (NH<sub>3</sub>-SCR) over Cu-exchanged zeolites at elevated temperatures. Here, we describe a highly efficient non-thermal plasma (NTP) deNO<sub>x</sub> process catalyzed by a Cu-embedded metal-organic framework, Cu/MFM-300(Al), at room temperature. Under NTP activation at 25°C, Cu/MFM-300(Al) enables direct decomposition of NO<sub>2</sub> into N<sub>2</sub>, NO, N<sub>2</sub>O, and O<sub>2</sub> without the use of NH<sub>3</sub> or other reducing agents. NO<sub>2</sub> conversion of 96% with a N<sub>2</sub> selectivity of 82% at a turnover frequency of 2.9 h<sup>−1</sup> is achieved, comparable to leading NH<sub>3</sub>-SCR catalysts that use NH<sub>3</sub> operating at 250°C–550°C. The mechanism for the rate-determining step (NO→N<sub>2</sub>) is elucidated by in operando diffuse reflectance infrared Fourier transform spectroscopy, and electron paramagnetic resonance spectroscopy confirms the formation of Cu<sup>2+</sup>⋯NO nitrosylic adducts on Cu/MFM-300(Al), which facilitates NO dissociation and results in the notable N<sub>2</sub> selectivity. Nitrogen oxide causes significant effects on the environment and human health. Xu et al. report, to the best of their knowledge, the first example of nonthermal plasma-activated direct decomposition of NO<sub>2</sub> over stable and efficient metal-organic framework-based catalysts at room temperature and without the use of NH<sub>3</sub> or other reducing agents.</p>
