“We've developed a very effective protection strategy for these narrow bandgap semiconductors, stabilizing them during photoreactions, which requires more than the traditional protective design,” said Dr. Zhao, a postdoctoral associate in Hu’s lab.
The researchers created a 3-nanometer-thick coating. Made from titanium oxide in Hu’s lab, the coating conformally encapsulates the photoabsorber. Loaded onto the coating are metal nanoparticles that serve as co-catalysts
