       Cu catalysts prepared by precipitation with NaOH are more active in the decomposition of CH₃OH than those precipitated with NH₃.  The difference is due to promoter action of the occluded Na salts.  The NaOH-precipitated catalysts, like other promoted Cu catalysts, favor HCOOCH₃ rather than HCOOH production from CH₃OH.
