Abstract With the acceleration of industrialization and increasing prominence environmental pollution problems, emission nitrogen oxides (NO x ) in atmosphere has become a global concern. These emissions are not only hazardous to human health, but also one main factors leading acid rain, photochemical smog climate change. Therefore, development implementation efficient denitrification technologies an important issue for protection. The present review focuses on research progress technology recent years, including traditional methods common technologies. At same time, advantages, limitations application prospects each method analyzed. mechanisms, influencing factors, advantages disadvantages catalysts discussed. In addition, future trends potential challenges It is expected that this will provide useful references promoting technology, which may help researchers choose high‐performance cost‐effective methods.

Abstract Metal‐modified catalysts have attracted extraordinary research attention in heterogeneous catalysis due to their enhanced geometric and electronic structures outstanding catalytic performances. Silver (Ag) possesses necessary active sites for ethylene epoxidation, but the catalyst activity is usually sacrificed obtain high selectivity towards oxide (EO). Herein, we report that using Al can help tailoring unoccupied 3 d state of Ag on MnO 2 support through strong metal‐support interactions (EMSIs), overcoming activity‐selectivity trade‐off epoxidation resulting a very conversion rate (~100 %) with 90 % EO under mild conditions (170 °C atmospheric pressure). Structural characterization theoretical calculations revealed EMSIs obtained by modification tailor Ag, modulating adsorption (C H 4 ) oxygen (O facilitating desorption, C conversion. Meanwhile, increased number positively charge + lowers energy barrier 4(ads) oxidation produce oxametallacycle (OMC), inducing unexpectedly selectivity. Such an promotion provides new promising pathways designing advanced metal selective reactions.

Cu-containing and Ce-modified OMS-2 catalysts were prepared at various calcination temperatures using the hydrothermal method tested for low-temperature CO oxidation. The structure, chemical compositions, physical–chemical properties of characterized XRD, N2 physisorption, XRF, Raman spectroscopy, SEM, high-resolution TEM with EDX, TPR-H2, XPS. incorporation Cu into Ce-OMS-2 sample facilitated transformation pyrolusite cryptomelane, as confirmed by spectroscopy data. In light-off mode, Cu/Ce-OMS-2-300 Cu/OMS-2 samples exhibited higher activity in oxidation (T90 = 115 121 °C, respectively) compared to Cu/Ce-OMS-2-450. After a long-run stability test, Cu/Ce-OMS-X demonstrated excellent performance: T80 increased 16% 7% calcined 300 °C 450 respectively, while 40%. found have an content nanodispersed copper sites on their surfaces. These contributed formation Cu2+-O-Mn4+ interface, which is responsible presence Ce3+ catalyst was increase its water vapor due reoxidation ability comparison Ce-free Cu/OMS-2.
