Green Hydrogen Production in an Optofluidic Planar Microreactor via Photocatalytic Water Splitting under Visible/Simulated Sunlight Irradiation
Abstract
The visible light-active Pt/TiO 2 photocatalyst thin films were prepared by photo-depositing Pt onto the sol–gel TiO 2 spin-coated films. An optofluidic planar microreactor was fabricated using a Pt/TiO 2 film-coated glass substrate as the bottom plate and an uncoated glass substrate containing a planar reaction chamber as the cover plate. The Pt/TiO 2 thin films were tested for the photocatalytic water splitting activity in the presence of methanol as the sacrificial agent to produce hydrogen under visible/solar light irradiation. The effect of catalyst film thickness, reactant flow rate, light intensity, and type of light source on the rate of hydrogen production was studied. The Pt/TiO 2 film with a thickness of 1650 ± 119 nm showed a highest rate of 16.35 mmol h –1 g –1 (4.7 μmol h –1 cm –2 ) hydrogen production at an optimum reactant flow rate of 0.3 mL min –1 under visible light (400 W metal halide lamp) irradiation. The stability study carried out for four cycles of 5 h runs proved that the photocatalyst was stable and the film was well adhered to the glass substrate. A hydrogen production rate of 0.766 mmol h –1 g –1 (0.22 μmol h –1 cm –2 ) and a solar to hydrogen conversion efficiency of 0.015% were obtained under a simulated solar light irradiation of ∼100 mW cm –2 intensity, proving the solar light activity of the Pt/TiO 2 film.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
