In the present work, we studied catalytic performance (activity and selectivity) of Pt supported on carbon systems modified with tin in glycerol oxidation H2O2 as oxidising agent at atmospheric pressure, 60 °C, base-free conditions. The conversion obtained monometallic catalyst was 37% remained unchanged addition Sn a ratio Sn/Pt = 0.4. two bimetallic PtSn catalysts were able to oxidise commerc...

A mesostructured cellular foam (MCF) silica was applied to support gold (Au) – platinum (Pt) alloy nanoparticles (NPs) for benzyl alcohol partial oxidation. catalytic synergy on bimetallic (Au)-platinum nanoparticle (NP) catalyst, referring that introducing Au Pt leading a higher performance has been observed. However, the essence of this synergistic effect is still under debate. In work, serie...

Abstract Low temperature oxidation of alcohols over heterogeneous catalysts is exceptionally challenging, particularly under neutral conditions. Herein, we report on an efficient, base-free method to oxidise glycerol a 0.5%Pd-0.5%Fe/SiO 2 catalyst at ambient in the presence gaseous H and O . The exceptional catalytic performance was attributed situ formation highly reactive surface-bound oxygen...

This work examines the sorption capacity of a natural biomass collected from an irrigation pond. The biomass mainly consisted of a mixture of chlorophyte algae with caducipholic plants. Biosorption experiments were performed in monometallic and bimetallic solutions containing different metals commonly found in industrial effluents (Cd, Cu and Pb). The biosorption process was slightly slower in ...

Understanding the interface between soluble metal complexes and supported particles is important in order to reveal reaction mechanisms a new generation of highly active homogeneous transition catalysts. In this study, we show that, case palladium forming on carbon (Pd/C) catalyst from Pd(0) complex Pd2dba3, nature deposited surface turns out be much richer than previously assumed, even if very...

This study investigates the effect of Pt/Pd ratio on oxidation activity and sulfur poisoning/regeneration diesel catalysts (DOC) using beta zeolites with high siliceous content as support. Formation Pt-Pd alloy leads to contraction cell lattice Pt in bimetallic catalysts, improving not only sintering resistance but also retaining a fraction Pd Pd2+ form. Moreover, improves particles, which enha...

Abstract For sustainable production of chemicals like hydrocarbons and oxygenates from renewable carbon sources electricity Fischer‐Tropsch synthesis is focused in current research. Aiming for this purpose, the development supported powdered shaped catalysts low‐temperature value‐added higher alcohols was addressed study. Promising support materials α‐Al 2 O 3 , SiO ZrO SiC were assessed influe...

The sulphate radical based advanced oxidation processes (AOPs) are highly in demand these days, owing to their numerous advantages. Herein, the Fe-Mn bimetallic oxide particle was used activate peroxymonosulphate (PMS) for Rhodamine B (RhB) degradation. Three catalysts were synthesized via chemical precipitation method with different concentrations of metals; (1:1), (1:2) and (2:1). best perfor...

Nickel (Ni)-promoted Molybdenum (Mo)-based catalysts are used for hydrotreatment processes in the chemical industry where exposed to high-pressure H2 at elevated temperature. In this environment, catalyst transforms into active phase, which involves reduction of oxide. Here, we report on first situ study alumina supported Ni- and Mo-based 1 mbar using ambient-pressure X-ray photoelectron spectr...
