Provided herein are methods and compositions for chemical mechanical polishing (CMP) of metals. The present methods and compositions involve the use of a corrosion inhibitor having the general formula C.sub.mH.sub.2m+1(OCH.sub.2CH.sub.2).sub.n-L-R in the CMP slurry composition, where m is an integer between 6 and 11, inclusive of end points, and n is an integer greater than or equal to 6, L is a bond, O, S, R.sup.1, SR.sup.1, or OR.sup.1, where R.sup.1 is a C.sub.1-4 alkylene; and R is an anionic group. The present methods and compositions can be used to achieve a high metal removal rate, while effectively inhibiting metal corrosion during CMP, and are particularly useful for CMP of cobalt (Co).

A method of increasing a density of carboxylic acids on a surface of a carbon nanoparticle is disclosed. The method includes contacting an oxygen-containing functional group on a surface of a carbon nanoparticle with a reducing agent to provide a hydroxyl group; reacting the hydroxyl group with a diazoacetate ester in the presence of a transition metal catalyst to provide an ester, the diazoacetate ester having the structure wherein R is a C1-8 hydrocarbyl, preferably tert-butyl, methyl, ethyl, isopropyl, allyl, benzyl, pentafluorophenyl, or N-succinimidyl; and cleaving the ester to provide a carboxylic acid group. Surface-functionalized carbon nanoparticles made by the method are also disclosed.
