Simultaneous catalytic oxidation mechanism of NO and Hg 0 over single-atom iron catalyst

Catalytic oxidation is a safe way to remove the above power plant emissions. Despite the fact that single-atom catalysts have excellent results for NO and Hg 0 oxidation, the reaction mechanism for simultaneous removal of NO and Hg 0 has not been fully described during the recent pioneering experiment. A single-atom iron catalyst based on a double-vacancy doped graphene substrate with four N atoms was used in this study to investigate the reaction mechanism of O 2 simultaneous catalytic of NO and Hg 0. Both potential pathways of simultaneous catalytic oxidation of NO and Hg 0 are enumerated by using the DFT method and energy span model. The study expanded the understanding of the reaction mechanisms that led to simultaneous removal of NO and Hg 0.

Effect of support on the performance of PtRu-based catalysts in oxidative steam reforming of ethanol to produce hydrogen

The OSRE's catalytic results in a series of PtRu-based samples was assessed using a fixed-bed flow reactor under atmospheric pressure. The PtRu supported on the ZrO2 and CeO2 catalysts demonstrated outstanding catalytic activity in the OSRE reaction under a low temperature for manufacturing the main H2 and CO2 containing lower CO and CH4 by-products, according to the results.

Removing Chlorobenzene via the Synergistic Effects of Adsorption and Catalytic Oxidation over Activated Carbon Fiber Loaded with Transition Metal Oxides

Low-concentration CB removal can be carried out by ACFs at a low temperature of 120 °C, u00b0C; the breakthrough time of CB over pristine ACFs can be reached at 15 h with a tenacious adsorbent concentration of 5000 ppmv and a space velocity of 20,000 hu22121. The CB removal occurred mainly to MnO2's catalytic oxidation; a preferable CB removal ratio was achieved at higher temperatures in the presence of more MnO2 than ever before.

Efficient Removal of Dibenzothiophene (DBT) over WO 3 -Mo-Al Catalysts in the Extractive Catalytic Oxidative Desulfurization (ECODS) System

A series of WO 3 -Mo-Al catalysts with various tungsten species uniformly incorporated into the Mo-Al catalyst were prepared by a simple one-pot synthesis scheme, as evaporation-based self-assembly aided by combined assembly by both soft and hard chemistry techniques. After repeated use for ten times, the 3WO 3-25Mo-Al catalyst provided the highest catalytic results when the DBT removal rate hits 100 percent.
