• Solvent polarity index and hydrogen uptake influence conversion selectivity. Pd/C PdRh/Al 2 O 3 showed excellent stability after three cycles of experiments. Orders effect catalyst process parameters are summarised as follows. Creosol Selectivity: >> Rh/Al Pt/SiO > Pd/Al Pt/C. Degree deoxygenation: loading temperature pressure agitation. This study reports mild hydrodeoxygenation (HDO) vanill...

The factors that control the oxidation of metals in bimetallic complexes are investigated in relation to the possibility of developing one-site addition two-metal oxidation reactions such as those that occur in the respiratory protein, hemerythrin. It is shown that the behavior of bimetallic complexes is not represented by the sum of the analogous monometallic parts because of metal and ligand ...

This work demonstrates the development of mesoporous trimetallic oxide scaffolds (TOSs) as heterogeneous catalysts for solvent-free transformation CO2 into various value-added products. The TOS catalyst was prepared using a solution-combustion protocol time- and energy-saving method cobalt, magnesium, cerium metal nitrate salts precursors ethylene glycol fuel system compared with their monometa...

The preparation of heterogeneous Fenton catalysts with both adsorption and catalytic properties has become an effective strategy for the treatment refractory organic wastewater. In this work, 4A-Fe@Cu bimetallic a three-dimensional core-shell structure were prepared by simple, template-free, surfactant-free methodology used in degradation Congo red (CR). results showed that open network positiv...

We report electrocatalytic oxidation of formic acid using monometallic and bimetallic dendrimer-encapsulated nanoparticles (DENs). The results indicate that the Au147@Pt DENs exhibit better electrocatalytic activity and low CO formation. Theoretical calculations attribute the observed activity to the deformation of nanoparticle structure, slow dehydration of formic acid, and weak binding of CO ...

Bimetallic platinum–rhenium catalysts supported on activated carbon were tested for the hydrodeoxygenation (HDO) of isoeugenol at 250 °C and 30 bar H2 in a batch reactor. The characterized by inductively coupled plasma atomic emission spectrometry (ICP-IES), N2 physisorption, electron microscopy (high-angle annular dark-field scanning transmission (HAADF-STEM), (TEM)), temperature-programmed re...

Bimetallic (Fe-Cu) and reduced graphene oxide (rGO)/FeCu catalysts at 0.2% wt. were developed by a co-precipitation method, modifying the Fe-Cu molar proportions (i.e., Fe40Cu60, Fe20Cu80 Fe10Cu90) tested for degradation of cytostatic drug, cyclophosphamide (CP) in aqueous solution using photo-Fenton process (UV-Vis). Physicochemical characterization was carried out complementary techniques (ga...

Abstract Active sites in Mo-based hydrotreating catalysts are produced by sulfidation. To achieve insights that may enable optimization of the catalysts, this process should be studied situ. Herein we present a comparative XAFS study where situ sulfidation Mo/δ-Al 2 O 3 and Ni/δ-Al is compared to δ-Al supported NiMo with different ratios. The also covers comparison Ni Mo using oxide supports as...

5-Hydroxymethylfurfural (HMF) is a biobased platform chemical that can be valorized into spectrum of valuable products. In this report, supported Ir, Ir–Co, Ir–Ni, and Ir–Ru catalysts were investigated for purpose. Only hydrogenation HMF to 2,5-bis-(hydroxymethyl)furan (BHMF) occurred over all catalysts. The effect the second metal (Co, Ni, Ru) on Ir/SiO2 was reflected by kinetic constants bein...

The first example of a mixed-metal amidoborane Na(2)Mg(NH(2)BH(3))(4) has been successfully synthesized. It forms an ordered arrangement in cation coordinations, i.e., Mg(2+) bonds solely to N(-) and Na(+) coordinates only with BH(3). Compared to ammonia borane and monometallic amidoboranes, Na(2)Mg(NH(2)BH(3))(4) can release 8.4 wt% pure hydrogen with significantly less toxic gases.
