Nanoparticles Synthesis

Narrow size distribution Palladium nanoparticles was synthesized by adding Pd precursor into a modified PMHS polymer solution, and then jelled by aluminium. The multi-functional polymer was characterized by NMR; Pd nanoparticle samples were characterized by TEM and catalytic activity was tested in methane partial oxidation reaction.

Background: The influence of the potassium metal cation on the graphitic carbon nitride (g-C3N4) photocatalyst has been studied in the partial oxidation of 5-hydroxymethyl-2-furfural (HMF) to 2,5-furandicarboxaldehyde (FDC). Objective: The aim of this study was to understand if the presence of K in C3N4 could increase the oxidative conversion of HMF to high added value species. Methods: Two sets of photocatalysts were prepared by following two different methodologies. In both series of the materials, the precursor of C3N4 was melamine with different types of the K containing species including KCl and KOH in one case and KNO3 alone in the other case. However, for both series of photocatalysts, materials were prepared with different amounts of potassium. Results: The results obtained by using materials prepared by the two different methodologies indicate that in both cases the presence of K was almost irrelevant at least for the lower amounts of potassium content. On the contrary, its presence was beneficial for the activity versus the photocatalytic partial oxidation reaction of the alcohol for the highest K content. Conclusion: Some of the prepared K containing g-C3N4 materials showed increased photocatalytic activity for the partial oxidation reaction of HMF in water, particularly by using natural solar light as the irradiation source.

Partial Oxidation Reaction

In the present work, several parameters affecting on the catalytic behavior were studied in the process of partial oxidation of methanol to formaldehyde, such as: Mo/Fe ratio in unsupported catalysts, weight percent of the metallic phase in the supported catalysts, the effect of different supports, the method of Mo-Fe deposition on the supports, and the stability of the prepared catalysts against coke. These catalysts were characterized by X-ray diffraction (XRD), Fourier Transform Infra Red (FT-IR), Thermogravimetric Analysis (TGA), Scanning Electron Microscopy (SEM), N2 adsorption-desorption, and Atomic Adsorption Spectroscopy (AAS) methods. The best results (the methanol conversion = 97 % and formaldehyde selectivity = 96 %) were obtained for Mo-Fe/g-Al2O3 prepared by co-precipitation method with Mo/Fe = 1.7, 50 wt.% of Fe-Mo phase, 2 mL/h methanol flow rate, and 120 mL/min air flow rate at 350 oC.
