Vulcan XC-72 samples were functionalized with methanol (MeOH) by Intermittent Microwave Heating (IMH) under different treatment conditions. To assess the effectiveness of proposed method citric acid functionalization was also performed as comparison. The obtained carbonaceous supports used to synthesize Pt/C-MeOH and Pt/C-CA nanocatalysts. surface assessed using them support for Pt/C nanocataly...

Functionalization of carbon nanotube (CNT) was performed, during preparation of Fischer–Tropsch synthesis (FTS) via cobalt nanocatalysts, to modify the surface properties of CNT support. Common and functionalized CNT supported cobalt nanocatalysts were prepared using impregnation wetness method with cobalt loading of 15 wt.%. The catalysts were characterized by Brunauer–Emmett–Teller (BET), Fou...

In this paper, we demonstrate a monolithic integrated micro direct methanol fuel cell (μDMFC) for the first time. The monolithic integrated μDMFC combines proton exchange membrane (PEM) and Pt nanocatalysts, in which PEM is achieved by the functionalized porous silicon membrane and 3D Pt nanoflowers being synthesized in situ on it as catalysts. Sulfo groups functionalized porous silicon membran...

The use of metal-based heterogeneous catalysts for the degradation N-containing organic dyes has attracted much attention due to their excellent treatment efficiency and capability. Here, we report synthesis heterometals (Ni Pd)-incorporated Fe3O4 (Ni-Pd/Fe3O4) yolk-shelled nanospheres catalytic reduction using a facile combination solvothermal high-temperature annealing steps. Benefiting from ...

In the present study, PtRuCe/MWNTs nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (MOR). To characterize the nanocatalysts, TEM, XRD, EDS and XPS are investigated. Cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activ...

Novel effluent treatment solutions for dangerous organic pollutants are crucial worldwide. In recent years, chemical reduction using noble metal-based nanocatalysts and NaBH4, a reducing agent, has become common practice eliminating contaminants from aquatic environments. We suggest straightforward approach to synthesizing magnetic cellulose nanocrystals (CNCs) modified with magnetite (Fe3O4) s...

Reaction dynamics in gases at operating temperatures the atomic level are basis of heterogeneous gas–solid catalyst reactions and crucial to function. Supported noble metal nanocatalysts such as platinum interest fuel cells diesel oxidation catalysts for pollution control, practical ruthenium explored ammonia synthesis. Graphite graphitic carbons supports nanocatalysts. Despite considerable lit...
