Colloid Catalysis

Colloids are a technique to get over these restrictions of traditional catalyst preparation techniques. The required support is then covered with NPs that were first generated in a solvent by reduction of dissolved metal precursors. As an alternative, they can be utilised straight away to make bulk catalysts without a support. Colloids are heterogeneous mixes of two materials in chemistry where minute particles of one material are scattered in another material. Small particles suspended in another material are referred to as the dispersed phase, and the substance in which they are suspended is referred to as the dispersion medium. For instance, the liquid phase of water is the dispersed phase in the fog, while other gases are the dispersion medium. Colloidal dispersed phase particles are so tiny that we cannot see them with 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
