چکیده
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 by using nanotubes (TiO2 NTs) as photoanode Pt free Ni foam cathode improve Hydrogen Evolution Reaction (HER). FA reaction rate normalized for lamp specific power account different photon flux rates higher process. is a promising strategy valorization biomasses simultaneous production in spite cost bias.

Photocatalytic H2 production from water with rhenium and cobalt complexes.
Photocatalytic hydrogen production in pure water for three component systems using a series of rhenium-based photosensitizers (PS) and cobalt-based water reduction catalysts (WRC), with triethanolamine (TEOA) as an irreversible electron donor, is described. Besides the feasibility of this reaction in water, key findings are reductive quenching of the excited state of the PS by TEOA (k(q) = 5-8 ...
متن کاملPhotocatalytic H2 evolution on MoS2-TiO2 catalysts synthesized via mechanochemistry.
At present, composite photocatalysts containing MoS2 as a co-catalyst and a subjective semiconductor material are usually obtained via various complex reduction methods using NH4MoS4 or Na2MoO4 as a precursor. In this work, a simple method was proposed to synthesize MoS2-TiO2 composite photocatalysts via mechanochemistry using MoS2 as a direct precursor. 4.0% MoS2-TiO2 after ball-milling at 300...
متن کاملCarbon-ensemble-manipulated ZnS heterostructures for enhanced photocatalytic H2 evolution.
In this paper, we demonstrate a facile design of ZnS-based heterostructures tailored by versatile glucose-derived carbon ensembles, including carbon dots (CDs) and thin carbon shells, via hydrothermal synthesis. Tuning the content of glucose allows interesting and simple conversion from CDs to carbon shells on the surfaces of ZnS nanospheres. The as-formed ZnS/carbon nanocomposites exhibit an e...
متن کاملActive hydrogen species on TiO2 for photocatalytic H2 production.
Photocatalytic H2 production over TiO2 has attracted tremendous attention and achieved great progress, but the active hydrogen species is still unknown. Employing a rutile TiO2(110) surface as a model catalyst we report here for the first time the direct observation of photocatalytic H2 production under ultrahigh vacuum conditions during UV-light irradiation at 115 K and the identification of n...
متن کاملA novel sandwich-type polyoxometalate compound with visible-light photocatalytic H2 evolution activity.
A tin(II) tungstosilicate derivative K(11)H[Sn(4)(SiW(9)O(34))(2)]·25H(2)O with four sandwiched Sn(2+) cations was prepared by reaction of SnCl(2), KCl and Na(10)[α-SiW(9)O(34)]·xH(2)O. Visible-light photocatalytic H(2) evolution activity was observed with Pt nanoparticles as co-catalyst and methanol as sacrificial agent.
