AI Thread Summary
A recent development in water splitting technology has been reported, highlighting a catalyst made from Co4O4 stabilized with bulky polytungstate ligands. This catalyst efficiently converts water into hydrogen and oxygen by spontaneously organizing into its active form using cobalt, tungsten, and phosphate salts. The process involves tris-(2,2'-bipyridyl)ruthenium(III) as an oxidant in the photocycle, although its stability remains unaddressed. If the ruthenium oxidant can be recycled effectively, this breakthrough could lead to the production of cheap, high-purity hydrogen, marking a significant advancement in renewable energy. The lead author of the study is an undergraduate, underscoring the potential for innovative contributions from emerging researchers.

Pretty exciting development to convert water to hydrogen and oxygen appears in http://www.sciencemag.org/cgi/content/abstract/science.1185372" ).

The catalyst is based on Co4O4 stabilized with bulky polytungstate ligands. The best part is that the complex spontaneously organizes into the active form by combining salts of cobalt, tungsten and phosphate. It doesn't get much easier than that! Tris-(2,2'-bipyridyl)ruthenium(III) is reported to by the oxidant in the photocycle but its stability in the cycle isn't mentioned. If the ruthenium oxidant is recycled this could be really big. I can't wait to read the hardcopy.

WOW! Could cheap abundant high purity hydrogen be just around the corner?

Awesome! Thanks for posting this.
 
Hehe and an undergraduate is the lead author!
 

Thread 'Solubility of MgSO47H2O in water'

It seems like a simple enough question: what is the solubility of epsom salt in water at 20°C? A graph or table showing how it varies with temperature would be a bonus. But upon searching the internet I have been unable to determine this with confidence. Wikipedia gives the value of 113g/100ml. But other sources disagree and I can't find a definitive source for the information. I even asked chatgpt but it couldn't be sure either. I thought, naively, that this would be easy to look up without...

Thread 'Why does having 8 valence electrons make an element inert?'

I was introduced to the Octet Rule recently and make me wonder, why does 8 valence electrons or a full p orbital always make an element inert? What is so special with a full p orbital? Like take Calcium for an example, its outer orbital is filled but its only the s orbital thats filled so its still reactive not so much as the Alkaline metals but still pretty reactive. Can someone explain it to me? Thanks!!
