Electrochemical oxidation of 5-hydroxymethylfurfural over a molybdenum sulfide modified nickel-based catalyst

Oxidation of Methanol using Carburized Molybdenum Catalyst

Molybdenum catalysts carburized in CH4/H2 exhibited activity for methanol electrooxidation (MOR) in half cell measurements. Mo carburized at 773 and 873 K showed high electrooxidation of methanol compared to carburization at other temperatures. Catalyst characterization was carried out by XRD and TPC. The active carbide species responsible to facilitate the MOR was the Mo oxycarbide and –Mo2C s...

Selective oxidation of 5-hydroxymethylfurfural to 2,5- diformylfuran over intercalated vanadium phosphate oxides

Effect of Reaction Pressure and Carrier Gas on Toluene Disproportionation over Molybdenum-zsm-5 Catalyst

A study was conducted to evaluate the effect of reaction pressure on the toluene disproportionation reaction using ZSM-5 zeolite based catalyst impregnated with molybdenum. Results showed that there is a marked difference in toluene conversion and xylenes selectivity using nitrogen and hydrogen carrier gases and the reaction pressure. Toluene conversion under nitrogen pressure was higher than u...

An Electrochemical Investigation of Methanol Oxidation on Nickel Hydroxide Nanoparticles

In this work, a nickel-modified glassy carbon electrode (GCE) was prepared using a potentiostatic method in 0.1 M acetate buffer solution at pH 4.0 containing 1.0 mM nickel nitrate. Nickel hydroxide nanoparticles were prepared using consecutive potential scanning in 0.1 M NaOH solution. The as-prepared catalyst was characterized by field emission scanning electron microscopy and electrochemical...

Electrochemical generation of hydrogen from acetic acid using a molecular molybdenum–oxo catalyst†‡

We recently reported the catalytic generation of hydrogen from water mediated through the in situ reduction of the molybdenum(IV)–oxo complex [(PY5Me2)MoO] 2+ (1; PY5Me2 1⁄4 2,6-bis(1,1-bis(2pyridyl)ethyl)pyridine) at a mercury electrode. To gain further insight into this unique molecular motif for hydrogen production, we have now examined the competence of this complex for the catalytic reduct...
