Constructing a high concentration CuO/CeO2 interface for complete oxidation of toluene: The fantastic application of spatial confinement strategy

Stabilized inverse Y2O3/Cu interfaces boost the performance of the reverse water–gas shift reaction

“…2d), which can be attributed to the fact that the size of Y 2 O 3 is related to the stability of the interface structure. 12,14 The particle size results from the XRD patterns also confirmed that the inverse Y 2 O 3 /Cu catalyst remained highly stable during the long-term stability process (Fig. 4e).…”

“…The construction of stable metal-oxide interfaces has been a hot topic in the field of heterogeneous catalysis, especially conventional supported catalysts. [12][13][14][15] Stable Cu-oxide interfaces can be maintained by decreasing Cu loading to fabricate highly dispersed Cu sites, designing reducible oxide shells to obtain the SMSI effect and synthesizing Cu-based catalysts with special spinel structures. 6,[16][17][18][19][20][21][22] However, these methods inevitably lead to fewer initial or exposed active Cu species, resulting in unsatisfactory catalytic activity.…”

A [Cu2O2]2+ Core in Cu/ZSM-5 for Efficient Selective Catalytic Oxidation of Nitrogen-Containing VOCs and NH3

“…x 3 (11) According to the results of surface acidity, the LA site is strongly dominant in the Cu-modified samples, which plays a role in the adsorption of DMF and reactive intermediate species (−NCO, −NH x ). For the oxidation of adsorbed DMF and −NH x as eqs 8 and 10, the [Cu 2 O 2 ] 2+ cores are key to providing the necessary reactive oxygen based on the results of redox properties (Figure 2f) and dynamic behaviors of the active site (Figure 3e).…”

“…Volatile organic compounds (VOCs) are the main precursors of ozone and photochemical smog, seriously harmful to the environment and human health, attracting much public attention. − Nitrogen-containing VOCs (NVOCs) such as amides, nitrile, amines, and nitro-compounds, which originate primarily from industrial processes and motor vehicles under low-speed driving, are often foul-smelling and highly toxic and are more harmful than conventional VOCs. − So far, various methods have been developed for NVOC removal, such as absorption, thermal combustion, and catalytic oxidation. With advantages in purification efficiency and cost, catalytic oxidation is one of the most promising methods. ,− Different from other VOCs oxidation, the N 2 selectivity during selective catalytic oxidation (SCO) of NVOCs must be considered as an important target to avoid the secondary pollution of NO x . − Therefore, the cooperative control of VOCs and NO x is the key issue in eliminating NVOCs.…”
