Final Report Summary - OPTIMLIGHTHARVEST (Large Scale Architectures with Nanometric Structured Interfaces for Charge Separation, Transport and Interception)

The development of new methods for building synthetic architectures spanning over the molecular, nanometric, and macroscopic scales is a challenging task that the OptimLightHarvest project addressed by employing several strategies that combine nanoscale building blocks and molecular components. A key concept implemented in the research aimed at using nanowires as templates for constructing well controlled architectures that bridge over the micro-, nano-, and molecular-scales. Nanowires were selected as templates owing to the unique structural characteristics and geometrical aspect ratio of nanowires reaching 1000 (for example, nanowire with diameter of 30nm and length of 30 microns). The nanowire templates were functionalized with tailor-made materials such as oxides and noble metals using new methods that were developed during the project. We formed unique hybrid architectures that exhibit improved photocatalytic activity, charge transfer characteristics, and customized morphologies. We demonstrated several novel routes for utilizing molecules for controlling the fine structural and electronic details of the hybrid nanostructures spanning the molecular, nano, and micron scales in their design with direct implications for hybrid nanostructure design, synthesis and function. For example, the photocatalytic properties of a widely studied material such as Titania can be tuned and improved by relying on inorganic-organic hybrid materials and anneal process and by using nanowires as structural templates. The exceptional reactivity of the Titania-based photocatalyst is achieved by controlling the thin film morphology, structural details and designed defects that affect the oxide electronic structure.
Within the frame of the project we established new concepts related to design of hybrid nanostructures and presented new methods that may be extended to other types of materials and provide new tools for controlling reactivity, charge transfer, and functionality using hybrid nano structures in general.
