H2HUBB TAKEAWAY
In a laboratory model, following their full spectroscopic and electrochemical characterization, the dyes were then employed to sensitize the nanocrystalline TiO2- or SnO2-based photoanodes of three-electrode DS-PECs, and the corresponding performances in terms of photocurrent production and hydrogen generation, as well as electrode stability, were assessed under several different conditions. The authors concluded that preliminary density functional theory (DFT) computational investigations indicated that the dyes presented the correct electronic structure and energy levels alignment for their desired application in devices. These findings from a laboratory model add evidence supporting molecular hydrogen's biological and therapeutic potential in the model studied.

What Effects Did Molecular Hydrogen Have?
In this work, the researchers report the design and synthesis of two new organic D-A-π-A dyes endowed with a common benzothiadiazole-dithienosilole (BTD-DTS) central core, and their evaluation as anodic sensitizers in dye-sensitized photoelectrochemical cells (DS-PEC) aimed at molecular hydrogen generation. Following their full spectroscopic and electrochemical characterization, the dyes were then employed to sensitize the nanocrystalline TiO2- or SnO2-based photoanodes of three-electrode DS-PECs, and the corresponding performances in terms of photocurrent production and hydrogen generation, as well as electrode stability, were assessed under several different conditions. The authors concluded that preliminary density functional theory (DFT) computational investigations indicated that the dyes presented the correct electronic structure and energy levels alignment for their desired application in devices.
