摘要: A nanodiamond according to the present invention has acidic functional groups, contains the acidic functional groups in a number density of 1 or more per square nanometer in the nanodiamond surface, and has a specific surface area of 150 m2/g or more. Particles of the nanodiamond preferably have a D50 (median diameter) of 9 nm or less. The nanodiamond is preferably derived from a nanodiamond synthesized by a detonation technique (in particular, an air-cooling detonation technique).

摘要: Acetic acid is produced by oxidation of methane with an oxygen-containing gas in the presence of an acid selected from concentrated sulfuric acid and fuming sulfuric acid, a palladium-containing catalyst and a promoter, preferably a copper or iron salt. The addition of a promoter and O2 to a system that includes a palladium-containing catalyst such as PdCl2 increases the rate of acetic acid formation from methane by more than an order of magnitude as compared with prior art and, in addition, inhibits the precipitation of Pd black.
