    Description

    General description

    Nitric acid (HNO3) is a highly corrosive mineral acid.[1][2] It is usually utilized for abstracting transition metal catalyst from single-walled carbon nanotubes (SWNTs) in order to purify them.[3] 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.[4]

    Application

    Nitric acid was used to increase the number of acid sites by altering the surface of activated carbon.[5]
    It may be used:
    • In combination with acetic anhydride and zeolite catalysts for the preparation of p-nitrotoluene with high regioselectivity.[6]
    • In the pretreatment of rice straw for enhanced production of xylose.[7]
    • To minimize the extent of cation ordering in LiNi0.5Mn1.5O4, a transition metal-substituted spinel material, by surface treatment.[8]
