WebBecause my professor today was like heterogenous works better and it’s more effective throughout application in a reaction than homogenous catalysts. But I think homogenous ones could be more effective since there is a higher interaction between them and the reactants ( same phase) making it more efficient in some way,I really don’t know now. Web8 sep. 2024 · In homogeneous, homo- means “same.” In heterogeneous, hetero- means “different” or “other.” In general use, the word homogeneous can describe something that is made up of parts or elements that are the same or very similar. It can also be used to describe two things as being the same or very similar in nature.
