Abstract Recently alcohol fuel cells has been increased consideration because of their environmental friendliness, high energy conversion efficiency and low emissions. Many effort have been made to improve the electro-oxidation performance of alcohols such as methanol, ethanol and propanol. In this work, a new method for ethanol oxidation based on core–shell titanium dioxide / carbon nanofib...

Constructing a hierarchical structure with tunable pore size is practical method to improve the capacity of photocatalytic hydrogen production catalysts. In this work, titanium dioxide/graphitic carbon nitride (TiO2/g-C3N4) nanofibers meso/macro-porous are fabricated by combining one-step electrospinning and calcination process, in which developed introducing polyvinylpyrrolidone liquid paraffi...

In the present paper, an experimental assessment was performed on the transient thermal performance of a heat sink filled by a phase change material (PCM) and PCM embedded with carbon nanofibers (CNFs) and titania (TiO2) nanoparticles as nanostructured materials. In order to enhance the thermal conductivity of PCM, CNFs and TiO2 nanoparticles at different loadings (0.5wt. % and 2 wt.% of CNFs a...

Nitrogen oxides (NOx) released in atmosphere by fuels combustion lead to photochemical smog and acidic rains and have negative effects on human`s nervous system. In this research nanocomposite membranes of Poly Vinylidene Fluoride (PVDF)/ Poly Dimethylsiloxane (PDMS) and Titanium Dioxide nanoparticles (TiO2) with different weight percentage of TiO2 (0.5 and 1) for adsorption of NOx were prepare...
