This work attempted to improve the catalytic performance of an anodic catalyst for use in direct methanol fuel cells by coating graphene aerogel (GA) with platinum nanoparticles. A hydrothermal, freeze-drying, and microwave reduction method were used load Pt–Ru bimetallic nanoparticles onto a aerogel. The mesoporous structure is expected enhance mass transfer electrode. XRD, Raman spectroscopy,...

Herein, we report a facile and efficient method for fabricating porous carbon flakes (PCFs)-supported nickel nanoplates (Ni NPs) as electrocatalysts methanol oxidation in alkaline media. The catalyst was fabricated one step using molten salt synthesis. Various techniques were used to characterize the morphology composition of Ni NPs@PCFs catalyst, these revealed that NPs dispersed finely across...

heating which are conducive to homogenous nucleation and a shorter crystallization time [14]-[16]; factors which are generally believed to be the prerequisite to the formation of monodisperse nanoparticles. Furthermore, microwave heating has also been found to increase reaction kinetics by one to two orders of magnitude [16]-[18]. Thus microwave assisted synthesis could pave way for the prepara...

Poly 8-(3-acetylimino-6-methyl-2,4-dioxopyran)-1-aminonaphthalene (PAMDAN) films were electrodeposited on platinum electrode (Pt), forming PAMDAN/Pt modified electrode, to study its utility in electrooxidation of iodide ion. The electrooxidation process was investigated by cyclic voltammetry. The effects of different factors e.g. scan rate, iodide ion concentration, film thickness and acid conc...

Simultaneous degradation of sulfadiazine, naproxen, diclofenac, ketoprofen and ibuprofen from drinking water was investigated by different technologies including photolysis, electrooxidation, photo-electrooxidation, zero-valent iron their combinations. All oxidation were very effective for the all drugs under anoxic conditions efficiency decreased oxic conditions. Results also revealed that can...

Platinum (Pt) nanopetals were electrodeposited on highly ordered silicon nanocones (SiNCs) and explored as the electrocatalyst for methanol oxidation reaction (MOR) for direct methanol fuel cells applications. Highly ordered SiNCs array fabricated using the porous anodic aluminum oxide as the template had a high surface area. Well-dispersed Pt nanopetals possessing high electrocatalytic surface...
