A recently discovered example of this type of substance is water- splitting cobalt oxide, which is not well understood but seems to use phosphate anions [AAN-"eye"-ahnz].
A recently discovered example of this type of substance is water- splitting cobalt oxide, which is not well understood but seems to use phosphate anions [AAN-"eye"-ahnz]. Another replaced the use of Schrock carbenes [KAHR-beenz]  and is named after Robert Grubbs. In the homogeneous or acid type of this, protons usually perform this kind of substance's main function, while the heterogeneous type often involves transition metals such as palladium or platinum. Commonly, one of these is used as an intermediate in a reaction, increasing the number of steps but lowering the activation energy. Name these materials unchanged by a chemical reaction that change the reaction rate.
