These limitations of traditional catalyst production techniques are solved by the use of colloids. By reducing dissolved metal precursors, NPs are created in a solvent and then applied to the chosen support. To prepare bulk catalysts, they can also be utilised directly without a support. Colloids are heterogeneous mixes of two substances in chemistry that have minute particles of one material scattered throughout another. The term "dispersion medium" refers to the material in which the tiny particles are suspended. The term "dispersed phase" refers to the mixture in which the particles are dispersed. For instance, the dispersed phase of a fog is water (liquid), while the dispersion medium is a variety of gases. Because they are so minute, dispersed phase particles in colloids are invisible to the naked eye. Colloids can be classified into the following two categories according to how the dispersed phase and dispersion medium interact:
Lyophilic colloids or lyophilic sols
Lyophobic colloids or lyophobic sols
