Nanoparticles of Ru3Pd6Pt have been previously produced by different synthesis routes that involve high temperatures and relative high pressures and long time. The usage of a conventional microwave assisted synthesis reduces environmental risk impact as well as the cost effective production in large scale with minimum set up modifications. These features are the motivations for the use of microwaves in the synthesis of the Ru3Pd6Pt catalyst for PEM fuel cell applications to reduce the Pt loading. In this communication a tri-metallic electrocatalyst was produced by the reduction of the corresponding metallic salts, RuCl3, PdCl2, and H2PtCl6 in ethylene glycol using a modified conventional microwave device. Oxygen reduction reaction kinetic analysis results conducted to a Tafel slope, (-b = 41.2 ± 1.7 mV dec-1) at low overpotential, and exchange current density (i0 = 3.01 ± 0.39 × 10-5 mA cm-2) in 0.5M H2SO4. This electrocatalyst exhibited good performance and stability in a single H2/O2PEM fuel cell.

In this study, ten 3-substituted indole derivatives at the 3rd position of indole nucleus were synthesized via Mannich reaction with microwave assisted synthesis and the conventional reflux heating method. Microwave assisted synthesis is more preferrable than reflux method since the microwave irradiation lead to a higher product yields with better purity and improved energy efficiency with shortened reaction time. The structures of 3-substituted indole derivatives were characterized by FT-IR, elemental analysis, 1H NMR and 13C NMR spectroscopy

L1 And L2

Two imine derivative ligands, L1 and L2, have been synthesized using the microwave assisted organic synthesis (MAOS) method from the reaction between bibenzoyl and L-tryptophan and L-Histidine, respectively. The ligands were further transformed into two nickel(II) complex, C1 and C2, as the precursors of catalysts in glucose conversion to sorbitol. The two NiO/SiO2 catalysts, K1 and K2, have been generated through the calcination process of complex C1 and C2, respectively, which were previously impregnated into silica. The K1 catalyst with average particle size of 5 nm shows good catalytic activity, with no presence of any nickel leached into the solution, and has successfully converted 21.99% of glucose into sorbitol. The K2 catalyst with average particle size of 10 nm also shows good catalytic activity and has successfully converted 32.30% of glucose into sorbitol, although it shows the presence of leached nickel.
