Visible light-induced PET-RAFT polymerization of methacrylates with novel organic photocatalysts

Tunable organic photocatalysts for visible-light-driven hydrogen evolution.

Photocatalytic hydrogen production from water offers an abundant, clean fuel source, but it is challenging to produce photocatalysts that use the solar spectrum effectively. Many hydrogen-evolving photocatalysts are active in the ultraviolet range, but ultraviolet light accounts for only 3% of the energy available in the solar spectrum at ground level. Solid-state crystalline photocatalysts hav...

Mechanism of Visible Light photocatalysts of Gold Nanoparticles (Au NPs) for Organic Synthesis

Visible Light-Induced Atom Transfer Radical Polymerization for Macromolecular Syntheses

Visible light-induced atom transfer radical polymerization (ATRP) of vinyl monomers are examined by using various photocatalysts systems including Type I and Type II photoinitiators, dyes, dimanganese decacarbonyl and semiconducting photocatalysts. The influence of various experimental parameters on the polymerization such as type of light sources and photocatalyts, and concentration of metal c...

Bottom-up design of 2D organic photocatalysts for visible-light driven hydrogen evolution.

To design two-dimensional (2D) organocatalysts, three series of covalent organic frameworks (COFs) are constructed using bottom-up strategies, i.e. molecular selection, tunable linkage, and functionalization. First-principles calculations are performed to confirm their photocatalytic activity under visible light. Two of our constructed 2D COF models (B1 and C3) are identified as a sufficiently ...

Facile Preparation of Silver Halide Nanoparticles as Visible Light Photocatalysts

In this study, highly efficient silver halide (AgX)-based photocatalysts were successfully fabricated using a facile and template-free direct-precipitation method. AgX nanoparticles, which included silver chloride (AgCl), silver bromide (AgBr) and silver iodide (AgI), were synthesized using different potassium halides and silver acetate as reactive sources. The size distribution of the AgX nano...
