Such testing could pave the way for the development of fuel cells based on inexpensive metals that could replace platinum - based fuel cells currently in use. (pnnl.gov)
Baran and his colleagues have previously studied decarboxylative cross-coupling reactions, where commonly - found carboxylic acids are transformed into many different molecules using inexpensive metal catalysts and techniques commonly used for amide - bond synthesis. (sciencedaily.com)
Investigators are pursuing several lines of attack to shrink the platinum content: using it more efficiently, replacing some or all of it with palladium (which performs similarly and is somewhat less expensive), replacing either of those precious metals with inexpensive metals, such as nickel or copper, and foregoing metals altogether.
