"The light absorber captures photons of sunlight and then harnesses the energy to generate the energetic electrons. Those energized electrons are then passed to the catalyst, which knits the hydrogen ions into H2. And the individual chains were so short that they allowed the catalyst's nickel ions—also in the solution—to nuzzle close enough to the nanoparticles to grab the electrons and knit H2 molecules together."

The words "capture", "harness", "nuzzle", "grab", and "knit" aren't in my scientific dictionary.It makes me wonder what this article is really about. Witchcraft?

Abstract

Homogeneous systems for light-driven reduction of protons to H2 typically suffer from short lifetimes because of decomposition of the light-absorbing molecule. We report a robust and highly active system for solar hydrogen generation in water that uses CdSe nanocrystals capped with dihydrolipoic acid (DHLA) as the light absorber and a soluble Ni2+-DHLA catalyst for proton reduction with ascorbic acid as an electron donor at pH 4.5, which gives >600,000 turnovers. Under appropriate conditions, the precious-metal-free system has undiminished activity for at least 360 hours under illumination at 520 nm and achieves quantum yields in water of over 36%.
