"The quantum yield of the new photocatalyst is 19% under visible light of wavelength 420 nm and is approximately 50 times the previously reported values (0.4%)*."
Just thought I'd throw this out for anyone looking at photocatalysis as a means of hydrogen production.
Another tungsten oddity, photo-luminescence of WS2:

"The edges of WS2 monolayers exhibit PL signals with extraordinary intensity, around 25 times stronger than that at the platelet’s center."
Looks like a pyramid-shaped atomically-small WS2 layer creates spontaneous room temperature photo-luminescence... perhaps something we could use to inject photons from the WS2 layers into water to assist dissociation.
