Shape effects of nanocrystal catalysts in different reactions have attracted remarkable attention. In the present work, three types α-Fe2O3 oxides with micromorphologies were rationally synthesized via a facile solvothermal method and adopted deep oxidation ethane. The physicochemical properties prepared materials characterized by XRD, N2 sorption, FE-SEM, HR-TEM, FTIR, situ DRIFTS, XPS, Mössbauer spectroscopy, Raman, electron energy loss H2-TPR. Moreover, formation oxygen vacancy surface...
Nitrogen-containing volatile organic compounds (NVOCs) can cause great damage to human health and the atmospheric environment. However, efficient oxidation of n-butylamine at low temperature effective inhibition production hazardous NH3 NOx byproducts remain a challenge. Herein, hierarchical Cu–Mn composite oxide catalysts with diverse ratios were rationally prepared, intrinsic role Cu Mn sites in was elucidated. As powerful catalyst, (1000 ppm; GHSV = 60 000 h–1) be completely mineralized...
The synergy between LaSrMnCoO<sub>6</sub> and H-ZSM-5 in the catalytic destruction of 1,2-dichloroethane based on dechlorination dehydrochlorination processes.
The selective hydrogenation of bio-derived furfural was investigated under mild conditions using a series supported palladium catalysts prepared by sol-immobilisation technique. Catalysts alumina and titania supports were more towards tetrahydrofurfuryl alcohol. catalytic activity 1.19% Pd/TiO2 evaluated different reaction higher selectivity alcohol observed when 2-propanol as solvent, the yield decreased temperature increased. performance Pd catalyst enhanced addition Pt 95% achieved....
The alkali metal potassium has the functions of structure promotion and electronic modulation in oxides.
Light alkanes (LAs), typical VOCs existing in both stationary and mobile sources, pose significant environmental concerns. Although noble metal catalysts demonstrate strong C–H bond activation, their effectiveness degrading LAs is hindered by inherent challenges, including poor chemical stability water resistance. Here, from a new perspective, we propose feasible strategy that adjusting the lengths within Pd clusters through partial substitution of smaller radius 3d transition metals (3dTMs)...
Oxygenated volatile organic compounds (OVOCs), emitted in large quantities by the chemical industry, are a major contributor to formation of ozone and subsequent particulate matter. For efficient catalytic oxidation OVOCs, challenges molecular activation intermediate inhibition remain. The construction bifunctional active sites with specific structures offers promising way overcome these problems. Here, Pd@Layered-CoOx/MFI catalyst core–shell was rationally fabricated though two-step ligand...
Silica and montmorillonite-supported silica nanoparticles were prepared via an acid one step sol-gel process. The synthesized solids characterized using XRD, FTIR, TEM N2 adsorption. effect of preparing temperatures on the structure properties studied. results show that increase annealing temperature from 25 to 200℃, don’t change amorphous state silica. While for clay platelets are delaminated during showed average particle size is increased by increasing due sintering clay-silica possessed...
Light alkanes make up a class of widespread volatile organic compounds (VOCs), bringing great environmental hazards and health concerns. However, the low-temperature catalytic destruction light is still challenge to settle due their high reaction inertness weak polarity. Herein, Co3O4 sub-nanometer porous sheet (Co3O4-SPS) was fabricated comprehensively compared with its bulk counterparts in oxidation C3H8. Results demonstrated that abundant low-coordinated Co atoms on Co3O4-SPS surface...
With the development of industrialization, emissions volatile organic compounds (VOCs) are steadily increasing, posing a significant risk to atmospheric quality and public health.
