Highly efficient elimination of nitrogen-containing volatile organic compounds (NVOCs) or NH3 via selective catalytic oxidation (SCO) while avoiding NOx is a strongly desired process for their control. However, limited by lack fundamental guidance such as accurate active site and reaction mechanisms, the targeted design high-performance catalysts faces severe challenges. Herein, ZSM-5 zeolites supported different copper species were used in SCO dimethylformamide (DMF) NH3. Optimal 8% Cu/ZSM-5 had highest N2 selectivity above 94%. Various situ spectroscopic characterizations DFT theoretical calculations precisely identified that μ-(η2:η2)-peroxo dicopper (bent; [Cu2O2]2+) core, which associated with two Al sites separated three SiO4 tetrahedra units 10-membered ring ZSM-5. The dynamic behavior DMF-SCO was revealed to be [Cu2O2]2+ transformed into mono-(μ-oxo) upon DMF adsorption, opposite occurred when O2 attacked. In DRIFTS elucidated pathway indicated disassociating N–H bond rate-determining step transforming N2. This work not only points way NVOCs but provides methodological implications study structures.

The selective transformation of 5-hydroxymethylfurfural (HMF) into valuable compounds such as 2,5-diformylfuran (DFF) and 2,5-dihydroxymethylfuran (DHMF) without using external redox agents presents a promising approach. In this research, new, cost-efficient copper–cerium bimetallic oxide catalyst (Cu1Ce5/γ-Al2O3) was developed to catalyze the intermolecular hydrogen transfer reaction HMF, facilitating production DFF DHMF. Here, HMF serves dual roles: donor, undergoing dehydrogenation supply hydrogen, acceptor, hydrogenation produce This process enables safe effective utilization atoms. analyzed various analytical techniques, including TEM, XRD, XPS, BET, H2-TPR, FT-IR. analyses density-functional theory (DFT) simulations revealed that creation Cu–O–Ce interfacial sites enhances activation C–OH C═O groups in HMF. enhancement provides bifunctional catalytic active for Under optimal conditions (140 °C, 12 h), DHMF were produced simultaneously with molar ratio 1:1. conversion rate reached 37.1%, selectivities at 46.6% 46.1%, respectively. Moreover, recovery experiments indicated maintained good stability after five cycles, DFF/DHMF consistently close one. demonstrates cost-effective method simultaneous through need agents.
