…The reaction rate is significantly increased compared to when platinum black and hydrogen ions are not present, and the state of platinum black and hydrogen ions remains the same after the reaction is completed. When the catalyst is a solid substance such as platinum black and the reactants are gases such as hydrogen and oxygen, it is called a heterogeneous catalytic reaction. When they are in the same solution phase, such as hydrochloric acid and methyl acetate aqueous solution, it is called a homogeneous catalytic reaction. … *Some of the terminology that refers to "homogeneous catalytic reactions" is listed below.
