General description
Nitric acid (HNO3) is a highly corrosive mineral acid. It is usually utilized for abstracting transition metal catalyst from single-walled carbon nanotubes (SWNTs) in order to purify them. The effect of nitric acid on the oxidation of multiwalled carbon nanotubes (MWCNTs) has been investigated by sample weight, Raman spectrum, solubility, morphology and alignment examinations.
Application
Nitric acid was used to increase the number of acid sites by altering the surface of activated carbon.
It may be used:
• In combination with acetic anhydride and zeolite catalysts for the preparation of p-nitrotoluene with high regioselectivity.
• In the pretreatment of rice straw for enhanced production of xylose.
• To minimize the extent of cation ordering in LiNi0.5Mn1.5O4, a transition metal-substituted spinel material, by surface treatment.
