Web1 day ago · Introduction. Naturally occurring lithium element consists of two stable isotopes, 6 Li & 7 Li, and each isotope plays a critical application in nuclear science and industry. 7 LiOH is usually used as a pH controller in the pressurized-water reactor (PWR) to slow down the corrosion of the pressure vessel wall. In this process, 7 Li needs to be enriched to a … WebFor instance, in some photo-reduction scenarios (e.g., dehalogenation of aromatic halides, H 2 production, and CO 2 reduction), reaction efficiencies on semiconductor nanoparticle catalysts in H 2 O/organic mixtures were reported to be much higher than those in the pure organic phase. 20–22 Although the effect of water as a direct reactant on photocatalytic …
