Summary: A Pt(ii)-based photo-hydrogen-evolving molecular device tethered to dimethyl-substituted viologens shows improved photocatalytic performance by utilizing multiple hydrogen evolution pathways taken by doubly and triply reduced species generated via consecutive photo-driven steps, despite being affected by Dexter-type energy transfer quenching. The results suggest new design strategies for finely tuned molecular devices controlling the photocatalytic HER.

Summary: The study reported the tuning of dominant products in the photocatalytic hydrogen transfer reaction over Pt/Nb2O5 photocatalysts using a support-induced modification strategy. It was found that the positively charged Pt (Pt delta+) species over 2D Nb2O5 nanoplates contributed to the reduction of phenylacetylene. This work sheds light on the design and application of Nb-based catalysts in the transfer hydrogenation of organics in photocatalysis.

Summary: In this paper, non-metallic elements doped ZrO2 photocatalysts were designed and further loaded with single-atom Pt based on first-principles. The relationship between the composition and performance of photocatalysts during doping and loading of single-atom was explained through electronic properties, and their photocatalytic hydrogen evolution performance was explored. Loading and doping had a synergistic effect on the modification of ZrO2, and doping effectively improved its catalytic performance.

Summary: This study investigates the deactivation mechanism of Pt/b-TiO2 NFs photocatalyst used in photocatalytic pure water splitting for hydrogen production, and proposes simple and effective methods to improve stability. The accumulation of H-2 and the adsorption of the product H2O2 are found to decrease the stability of the photocatalyst. Timely transfer of large amounts of H-2 and mechanical disturbance can significantly improve the stability of the catalyst.

Summary: In this study, a universal and rapid method using a newly developed water-soluble star polymer hydrogel is presented for direct and reproducible printing and patterning of freestanding functional thin films. The resulting thin films exhibit features such as high transmittance, high mechanical strength, multiresponsive self-healing capability, recyclability, and multifunctionality. Various humidity-sensing devices, including an actuating switch, a supercapacitive sensor, and a noncontact electronic skin, are easily constructed using the humidity-induced assembly techniques. This method shows universality and efficiency in the fabrication and assembly of controlled thin films for advanced flexible electronics.
