Low‐Temperature Remediation of NO Catalyzed by Interleaved CuO Nanoplates

Abstract

A copper(II)‐oxide‐based exhaust catalyst exhibits better activity than Pt‐ and Rh‐nanoparticle catalysts in NO remediation at 175 °C. Following theoretical design, the CuO catalyst is rationally prepared; CuO nanoplates bearing a maximized amount of the active {001} facet are arranged in interleaved layers. A field test using a commercial gasoline engine demonstrates the ability of the catalyst to remove NO from the exhaust of small vehicles.

Room-Temperature High-Performance H2S Sensor Based on Porous CuO Nanosheets Prepared by Hydrothermal Method

“…The porous structure is obviously different from the literature for those leaves-like or sheet structures of CuO. [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39] The surface area of these CuO nanosheets obtained based on the BET method is 10.03 m 2 ·g -1 . These porous CuO nanosheets are efficient for the gas flowing in and out, thus enhancing their gas sensing performance.…”

Direct Growth of CuO Nanorods on Graphitic Carbon Nitride with Synergistic Effect on Thermal Decomposition of Ammonium Perchlorate

“…As illustrated in Figure 1a, the g-C 3 N 4 sample had a characteristic peak at 27.4° and 13.2°, which could be indexed by the hexagonal g-C 3 N 4 (JCPDS87-1526) as the (002) and (100) diffraction plane peaks, corresponding to the interlayer stacking of aromatic segments with a distance of 0.326 nm, and the in-plane structural packing motif, respectively [32,33]. The diffraction peaks of the obtained CuO were indexed to the monoclinic phase of CuO (JCPDS05-0661) [34]. The diffraction peaks at 32.4°, 35.6°, 38.8°, 48.7°, 53.5°, 58.3°, 61.5°, 66.1°, 68.1°, 72.4°, 75.2° were observed (Figure 1a), corresponding to (1, 1, 0), (−1, 1, 1), (1, 1, 1), (−2, 0, 2), (0, 2, 0), (2, 0, 2), (−1, 1, 3), (3, 1, −1), (2, 2, 0), (3, 1, 1) and (2, 2, −2) [35].…”

Crystal-plane effects on surface and catalytic properties of Cu2O nanocrystals for NO reduction by CO

“…The catalytic reduction of NO by CO belongs to heterogeneous catalytic reaction, which is widely involved in many important processes such as adsorption of reactants, the conversion of adsorbed intermediates (surface reaction), and desorption of products. It is found that the use of copper-based catalysts is a suitable one for the catalytic reduction of NO by CO [4][5][6]. In recent years, our group have reported some work on catalytic removal of NO by CO with supported copper-based catalysts and achieved some meaningful results [7,8].…”
