郭新闻论文成果：Defect-Enriched N,O-Codoped Nanodiamond/Carbon Nanotube Catalysts for Styrene Production via Dehydrogenation of Ethylbenzene
nanodiamond/carbon nanotube hybrid nitrogen and oxygen codoping structural defect direct dehydrogenation styrene production
2023/3/6
Owing to the unique structure and enriched surface ketonic carbonyl group, nanodiamond (ND) shows excellent catalytic performance for dehydrogenation reaction. However, the agglomeration of predispers...
Chemical reactions are happening around us all the time – it’s obvious when you think about it, but how many of us do when we start a car, cook an egg, or fertilize the lawn?
Chemical reactions that are driven by light offer a powerful tool for chemists who are designing new ways to manufacture pharmaceuticals and other useful compounds. Harnessing this light energy requir...
Cornell chemists have discovered a class of nonprecious metal derivatives that can catalyze fuel cell reactions about as well as platinum, at a fraction of the cost.
