Structural regulation of single-atom catalysts for enhanced catalytic oxidation performance of volatile organic compounds

We introduce the basic features of VOCs total oxidation in catalytic VOCs total oxidation into CO 2 and H 2 O in this report, and then discuss the effects of various structural control techniques on catalytic results. Lastly, we review the current problems that have yet to be addressed and the challenges that are currently faced in this field, as well as future research and study recommendations for SACs in catalytic oxidation of VOCs.

Catalytic oxidation of dichloromethane over phosphate-modified Co 3 O 4 : Improved performance and control of byproduct selectivity by Co 3 O 4 defects and surface acidity

The catalytic oxidation of chlorinated volatile organic compounds is a critical topic in environmental catalysis, but the design of highly effective catalysts remains difficult. Phospho-modified Co 3 O 4 oxides in this work provided increased performance, increased durability, and much lower selectivities to Cl-containing byproducts relative to the original Co 3 O 4 in dichloromethane's catalytic oxidation. The improved results were due to the adsorption/activation of CH 2 Cl 2 on the surface acid sites, as well as synergistically fast oxidation of the reactive intermediates by the oxygen species that was activated on the oxygen vacancies.

Synthesis of ultra-thin 2D MnO 2 nanosheets rich in oxygen vacancy defects and the catalytic oxidation of n-heptane

So far, the majority of the studies on C 7 H 16 have concentrated on catalytic cracking rather than low temperature degradation, rather than low temperature degradation. The study of catalytic oxidation of C 7 H 16 as a long-chain alkanes has a certain guiding value for chemical degradation and mechanism analysis of complex organic compounds. Due to the synthesis of surface oxygen vacancies, surface reactive oxygen species play a vital role in catalytic oxidation.

MnCo-Layered double hydroxides nanosheets supported Pd nanoparticles for complete catalytic oxidation of formaldehyde at room temperature

Understanding the reaction mechanism will raise the catalytic activity by rationalizing the reaction mechanism. Pd nanoparticles were coated on pre-reduction uniform LDH nanosheets in this paper to produce Pd-decorated sodium borohydride-reduced Mn/Co layered double hydroxides. Characterizations revealed that the synergistic effect of the enabled Pd NPs and LDH, as well as several oxygen vacancies, was responsible for the effective removal of HCHO by Pd/LDH-NaBH 4 catalyst at ambient temperature.

Structural regulation of single-atom catalysts for enhanced catalytic oxidation performance of volatile organic compounds

Single-atom catalysts with 100% atom reuse and uniform active sites are often high in availability and good product selectivity, and promise a wide variety of applications. We introduce the principles of VOCs total oxidation reduction in catalytic VOCs total oxidation into CO 2 and H 2 O in this review, followed by a detailed analysis of various legislative policy issues on the catalytic's results.

Interaction between noble metals (Pt, Pd, Rh, Ir, Ag) and defect-enriched TiO 2 and its application in toluene and propene catalytic oxidation

The particle size, electronic state, as well as metal-support interaction of supported noble metal catalysts can all influence their VOC oxidation results. A series of noble metals were successfully loaded on TiO 2 modified by hydrogen reduction to investigate their effects on toluene and propene combustion. It was interesting to note that all of the noble metals could be well-dispersed on TiO 2 support in the low-surface area and modulated its properties. The Pd/TiO 2 and Pt/TiO 2 catalysts demonstrated excellent catalytic results by converting local electron transfer from TiO 2 to the noble metal NPs by the strong metal-support relationship, among them.

PMo 11 V polyoxometalate encapsulated into hollow mesoporous carbon spheres: A highly efficient and ultra-stable catalyst for oxidative desulfurization

PMo 11 V@HMCS had higher conversion of dibenzothiophene than PMo 11 V@AC, and could completely eliminate DBT in the model fuel in 30 minutes, according to the oxidative desulfurization experiments. In addition, because the nanoscale pore size in HMCS can safely confine and anchor the POM clusters and prevent the loss of catalytic active species, the catalyst also displayed outstanding recyclability and stability. The PMo 11 V@HMCS could be reused for at least twenty runs without a noticeable decrease in performance.

High-entropy intermetallics on ceria as efficient catalysts for the oxidative dehydrogenation of propane using CO 2

Propylene production and CO 2 utilization by using CO 2 can be a promising method for high-yield propylene production and CO 2 utilization. CO 2 -ODP conversion is of particular concern and benefit to the chemical industry, as well as net zero emissions. With a PtSn intermetallic structure, a senary catalyst supported on CeO 2 shows a much higher catalytic activity, C 3 H 6 selectivity, long-term stability, and CO 2 utilization efficiency at 600 b0C than previously reported.

Controlling effect of TiO 2 carrier on formed vanadium species for effective catalytic oxidization of chlorobenzene

This work, in comparison, this research focuses on the influence of TiO 2 surface chemistries on the properties of formed vanadium species during thermal activation. Both experimental and theoretical analyses are used to analyze TiO 2 loaded TiO 2 in depth. The Ti 4+ based catalyst converts chlorobenzene by catalytic oxidization of chlorobenzene to 98. 0 % at 250 °C, much larger than that of the Ti 3+ -generated catalyst.
