Special Issue Information

Dear colleagues,

In recent years, energy demand has increased progressively but it has also been accompanied by a reduction in the supply of fossil fuels. For this reason, the need for alternative, new, clean, renewable, and ecological energy resources have emerged. Because of the progressive decrease of fossil fuel reserves and the pollution caused by their utilization, hydrogen represents a promising choice for a future energy resource because it is pollution-free, storable, and in great demand by the fuel cell industries. In this context, the photocatalytic and electro-photocatalytic hydrogen production as energy vector from water and wastewater, represent the most important and promising strategies for renewable energy production resources. We cordially invite you to contribute your original research work or review articles to this Special Issue entitled "Recent Advances on Photocatalytic and Electro-Photocatalytic Hydrogen Production". In particular, in this Special Issue, the development of photocatalysts active under UV, visible or solar light, strategies to improve photocatalytic performances by means of heterojunctions, configurations of photocatalytic and photoelectrocatalytic reactors for the production of hydrogen will be considered.

In this work, the optimization of Ni amount on LaFeO3 photocatalyst was studied in the photocatalytic molecular hydrogen production from glucose aqueous solution under UV light irradiation. LaFeO3 was synthesized via solution combustion synthesis and different amount of Ni were dispersed on LaFeO3 surface through deposition method in aqueous solution and using NaBH4 as reducing agent. The prepared samples were characterized with different techniques: Raman spectroscopy, UltraViolet-Visible Diffuse Reflectance Spettroscopy (UV–Vis-DRS), X-ray Diffraction (XRD), X-ray Photoelectron Spectroscopy (XPS), X-ray Fluorescence (XRF), Transmission Electron microscopy (TEM), and Scanning Electron microscopy (SEM) analyses. For all the investigated photocatalysts, the presence of Ni on perovskite surface resulted in a better activity compared to pure LaFeO3. In particular, it is possible to identify an optimal amount of Ni for which it is possible to obtain the best hydrogen production. Specifically, the results showed that the optimal Ni amount was equal to nominal 0.12 wt% (0.12Ni/LaFeO3), for which the photocatalytic H2 production was equal to 2574 μmol/L after 4 h of UV irradiation. The influence of different of photocatalyst dosage and initial glucose concentration was also evaluated. The results of the optimization of operating parameters indicated that the highest molecular hydrogen production was achieved on 0.12Ni/LaFeO3 sample with 1.5 g/L of catalyst dosage and 1000 ppm initial glucose concentration. To determine the reactive species that play the most significant role in the photocatalytic hydrogen production, photocatalytic tests in the presence of different radical scavengers were performed. The results showed that •OH radical plays a significant role in the photocatalytic conversion of glucose in H2. Moreover, photocatalytic tests carried out with D2O instead of H2O evidenced the role of water molecules in the photocatalytic production of molecular hydrogen in glucose aqueous solution.
