An improved photocatalytic activity of H2production: a hydrothermal synthesis of TiO2nanostructures in aqueous triethanolamine

In this study, novel hydrothermal synthesis is used to explore the impact of photocatalytic activity on H2production using an aqueous solution of triethanolamine (TEoA) in TiO2nanostructures designed with varying molar concentrations of HCl, and the production of molecular hydrogen is explored as a function of molar concentration. A solar simulator is utilized to assess the photocatalytic activities of methyl orange degradation under UV light irradiation and molecular H2production. Also, XRD patterns and SEM images are explored to show agglomerated nanoparticle formation, and an EDX spectrum is employed to confirm TiO2compositions. The band gap analysis of produced nanostructures is performed using a UV-Vis spectrometer and is found to be varying in between 2.5 and 3.0 eV, while the maximum methyl orange degradation corresponds to 1.0 M concentration of HCl, indicating an enhanced hydrogen production. To meet the foreseeable future energy crises and worsening environmental challenges, we may need sustainable energy sources, and photocatalysis molecular H2production offers a viable alternative to fossil fuels that can be employed to tackle future difficulties.
