Advanced oxidation processes (AOPs) have been postulated as viable, innovative, and efficient technologies for the removal of pollutants from water bodies. Among AOPs, photo-Fenton shown to be effective degradation various types organic compounds in industrial wastewater. Monometallic iron catalysts are limited practical applications due their low catalytic activity, poor stability, recyclabili...

Two late transition metal catalysts based on 2,6-bis(imino)pyridine iron(II) were synthesized by introducing methyl substitution (catalyst A) and t-Butyl substitution (catalyst B) at the ortho position of the aryl rings of the ligand. Comparative ethylene polymerizations using the catalysts showed quiet different behaviors. The activity of catalyst A was higher than that of catalyst B in all of...

The recent surge of interest in non-noble-metal porphyrin and phthalocyanine catalysts has been prompted by their potential to replace Pt as cathodic catalysts in polymer electrolyte membrane fuel cells (PEMFCs). However, to realize the apparent benefits of the metal–N-coordinated catalysts in high-power fuel cells, advances in catalyst design and synthesis are required to produce catalysts wit...

Abstract The study investigates hydrogenation of CO 2 over mono- and bimetallic catalysts supported on biochar. In this reaction, iron–cobalt were shown to surpass monometallic iron cobalt in terms catalytic performance. optimal combination performance parameters was reached at an ratio 3 : 1. composition genesis the active phase Fe–Co catalyst identified, mechanism suggested for iron-dominated...

Catalyst activity and performance are the most important factors for selecting a catalyst in different processes. The Fischer-Tropsch synthesis is a very important synthesis that extensive action has been taken place to increase the activity of its catalysts in the recent century. Deactivation of the catalysts of the process is influenced by many factors, among which coking and sintering have c...

Nanometric Carbid Silicon (SiC) supported monometallic and bimetallic catalysts containing Fe, Co, Ni transition metals were prepared by wet impregnation method. Multiwall carbon nanotubes (MWCNTs) were synthesized over the prepared catalysts from catalytic decomposition of acetylene at 850°C by thermal chemical vapor deposition (TCVD) technique. The synthesized nanomaterials (catalysts and CNT...

We report the photocatalytic activity of iron-grafted mesoporous Pt/TiO2 catalysts, combining properties heterojunction photocatalysts with mesoporosity, for gas-phase production hydrogen from water-ethanol mixtures. GC–MS analysis reveals a preferential ethanol dehydrogenation reaction pathway, resulting in formation acetaldehyde high selectivity versus carbon dioxide, all catalysts investigat...

This study investigates the stability and activity of HZSM-5 doped with metals such as molybdenum, nickel, copper, and iron under hydrothermal conditions used for the direct liquefaction of microalgae. Catalysts have been prepared by ion-exchange techniques, and MoZSM-5 was also prepared by wet incipient impregnation for comparison. Hydrothermal liquefaction is considered a potential route to c...

Iron-containing zeolites are heterogeneous catalysts that exhibit remarkable activity in the selective oxidation of inert hydrocarbons and catalytic decomposition nitrous oxide (N2O). The reduction N2O is critical to both these functions, but experimental data tracking iron active sites during binding activation limited. Here, N2O-ligated Fe(ii) site iron-exchanged zeolite beta isolated charact...
