Titanium dioxide (TiO 2) is the most commonly used photocatalyst in many environmental applications but it can be used only under UV light owing to its high band gap energy (3.2 eV).

Most of the conventionally developed water-splitting photocatalysts, however, were only active under UV irradiation, and only a few have been demonstrated to operate under visible light, at up to ...

Researchers have developed "nanofibrous blankets" that float on contaminated water, using sunlight to break down pollutants.

Obviously, a photocatalyst requires light to work. However, the UBC researchers found that their PFAS elimination system doesn’t need as much UV light as other methods.

"The 'red shift' allows the photocatalyst to absorb visible light by extending the active region of the nanocomposite from UV to the visible," Jian Ku Shang of the department of materials science and ...

More specifically, the study's core experiments involved the application of KQGZ as a photocatalyst under visible light to defluorinate a range of PFASs, including polytetrafluoroethylene (PTFE ...

Titanium dioxide (TiO2) is a photocatalyst that interacts with UV light to accelerate chemical reactions. An even mix of Prussian blue and TiO2 nanoparticles coat the paper, which then takes on a ...
