“…7,8 Recently, solid hydrogen storage materials have been widely investigated and used to produce high purity hydrogen by hydrolysis reaction. 9,10 As for hydrogen generation materials, especially, borohydrides (i.e., NaBH 4 , MgBH 4 , LiBH 4 ), [11][12][13] light weight metals (i.e., Mg and Al) 14,15 and metal hydride (i.e., MgH 2 and CaH 2 ) 16,17 have been studied. Among these materials, magnesium-based materials have attracted much attention for hydrogen production due to their relatively low cost, high theoretical hydrogen generation, and environmentally friendly products.…”

“…The photon flux is received through the photocatalytic material surface that activates the active sites [ 41 ]. Through this process, the splitting in the outer energy levels takes place and led to the production of hot electrons [ 42 , 43 , 44 , 45 , 46 ]. These electrons are collected on the surface of the photocatalytic material and cause the production of J ph [ 47 ].…”

This study is very promising for providing a renewable enrgy (H2 gas fuel) under the elctrochemical splitting of the wastwater (sewage water). This study has double benefits: hydrogen generation and contaminations removel. This study is carried out on sewage water, third stage treated, from Beni-Suef city, Egypt. Antimony tin oxide (ATO)/polyaniline (PANI)/PbI2 photoelectrode is prepared through the in situ oxidative polymerization of PANI on ATO, then PANI is used as an assistant for PbI2 deposition using the ionic adsorption deposition method. The chemical structural, morphological, electrical, and optical properties of the composite are confirmed using different analytical tools such as X-ray diffreaction (XRD), scanning electron microscope (SEM), transmision electron microscope (TEM), Fourier-transform infrared spectroscopy (FTIR), and UV-Vis spectroscopy. The prepared PbI2 inside the composite has a crystal size of 33 nm (according to the peak at 12.8°) through the XRD analyses device. SEM and TEM confirm the hexagonal PbI2 sheets embedded on the PANI nanopores surface. Moreover, the bandgap values are enhanced very much after the composite formation, in which the bandgap values for PANI and PANI/PbI2 are 3 and 2.51 eV, respectively. The application of ATO/PANI/PbI2 nanocomposite electrode for sewage splitting and H2 generation is carried out through a three-electrode cell. The measurements carreid out using the electrocehical worksattion under th Xenon lamp (100 mW.cm−2). The produced current density (Jph) is 0.095 mA.cm−2 at 100 mW.cm−2 light illumination. The photoelectrode has high reproducibility and stability, in which and the number of H2 moles is 6 µmole.h−1.cm−1. The photoelectrode response to different monochromatic light, in which the produced Jph decreases from 0.077 to 0.072 mA.cm−2 with decreasing of the wavelengths from 390 to 636 nm, respectively. These values confirms the high response of the ATO/PANI/PbI2 nanocomposite electrode for the light illuminaton and hydrogen genration under broad light region. The thermodynamic parameters: activation energy (Ea), enthalpy (ΔH*), and entropy (ΔS*) values are 7.33 kJ/mol, −4.7 kJ/mol, and 203.3 J/mol.K, respectively. The small values of ΔS* relted to the high sesnivity of the prepared elctrode for the water splitting and then the hydrogen gneration. Finally, a theoretical study was mentioned for calculation geometry, electrochemical, and thermochemistry properties of the polyaniline/PbI2 nanocomposite as compared with that for the polyaniline.

“…, at room temperature, via hydrolysis. 2 However, one major issue with this approach is that the regeneration of NaBH 4 from the hydrolytic products formed after H 2 production generally carries a high energy penalty and thus requires, e.g. , high temperatures (400–500 °C).…”
