In this work the photocatalytic (PC) and photoelectrocatalytic (PEC) reforming of furfuryl alcohol (FA) under environmental friendly conditions was investigated. Both H2 evolution partial oxidation to furfuraldehyde were followed. For first time TiO2 based photocatalysts studied activity home prepared compared with that commercial ones both UVA simulated solar irradiation. PEC tests performed b...

Conductive polypyrrole–polyaniline/TiO2 nanocomposites (PPy–PANI/TiO2) were prepared by in situ oxidative copolymerization of pyrrole and aniline monomers in the presence of TiO2. For comparison studies, polypyrrole/TiO2 (PPy/TiO2) and polyaniline/TiO2 (PANI/TiO2) were also prepared. The samples were characterized by X-ray diffraction, transmission electron microscopy, UV-vis diffuse reflectanc...

The characterization of mixed oxides of TiO2/SiO2 and TiO2/Al2O3 prepared by sol-gel methods is described. Application of the TiO2/Al2O3 material for the photocatalytic decomposition of salicylic acid gave improved activity relative to TiO2-only materials. The photocatalytic activity of TiO2/SiO2, TiO2/Al2O3, and TiO2 toward the photocatalytic decomposition of phenol demonstrated the enhancemen...

The electrocatalytic oxidation of meglumine and gadoterate (Gd-DOTA) on a TiO2-Ni(SO4)0.3(OH)1.4 composite anode was investigated in alkaline medium (5 M KOH) using cyclic voltammetry chronoamperometry. prepared by hydrothermal method the morphology structure produced nanoparticles were studied scanning electron microscopy with energy-dispersive X-ray spectroscopy, diffraction, atomic force mic...

A simple, robust and versatile hydrothermal synthesis route to in situ functionalized TiO2 nanoparticles was developed using titanium(IV) isopropoxide as Ti-precursor and selected silane coupling agents (3-aminopropyltriethoxysilane (APTES), 3-(2-aminoethylamino)propyldimethoxymethylsilane (AEAPS), and n-decyltriethoxysilane (DTES)). Spherical nanoparticles (ca. 9 nm) with narrow size distribut...

Cobalt and nickel have become important strategic resources because they are widely used for renewable energy technologies rechargeable battery production. Cementation, an electrochemical deposition of noble metal ions using a less as electron donor, is option to recover Co Ni from dilute aqueous solutions these ions. In this study, cementation experiments recovering Co2+ Ni2+ sulfate chloride ...
