Description

General description

Nitric acid (HNO₃) is a highly corrosive mineral acid.[96][97] It is usually utilized for abstracting transition metal catalyst from single-walled carbon nanotubes (SWNTs) in order to purify them.[98] 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.[12]

Application

Nitric acid was used to increase the number of acid sites by altering the surface of activated carbon.[00]
It may be used:

• In combination with acetic anhydride and zeolite catalysts for the preparation of p-nitrotoluene with high regioselectivity.

[01]

In the pretreatment of rice straw for enhanced production of xylose.

[02]

To minimize the extent of cation ordering in LiNi_0.5Mn_1.5O₄, a transition metal-substituted spinel material, by surface treatment.
