Design and fabrication of self-suspending aluminum-plastic/semiconductor photocatalyst devices for solar energy conversion.

The design and synthesis of self-suspending photocatalyst device with easy recyclability is important for practical application. Here, this work utilizes aluminum-plastic package waste as raw material to prepare an aluminum-plastic supported TiO (AP-TiO) photocatalyst device through 3D printing design and surface deposition method. A series of characterizations were carried out to explore the structure, morphology and performance of the AP-TiO device.

Pt-Chitosan-TiO for Efficient Photocatalytic Hydrogen Evolution via Ligand-to-Metal Charge Transfer Mechanism under Visible Light.

The Pt-chitosan-TiO charge transfer (CT) complex was synthesized via the sol-gel and impregnation method. The synthesized photocatalysts were thoroughly characterized, and their photocatalytic activity were evaluated toward H production through water reduction under visible-light irradiation. The effect of the preparation conditions of the photocatalysts (the degree of deacetylation of chitosan, addition amount of chitosan, and calcination temperature) on the photocatalytic activity was discussed.
