heterogeneous catalysis

Catalysis - It has been mentioned earlier that a catalyst usually increases the rate of reaction. A catalyst is not consumed in the reaction, it is used up in one step and then released in the next step. Catalytic reactions can be classified into two types. They are i) Homogenous reaction..

Catalytic reactions are classified as homogeneous catalysis or heterogeneous catalysis. When a catalyst mixes homogenously with the reactants and forms a single phase it is called a homogenous catalyst. When a catalyst exists in a different phase from that of the reac..

Heterogeneous catalysis is extensively used in chemical industry. Hence, development, selection and application of solid catalysts forms an important area in surface chemistry studies. The nature of the solid catalyst has profound effects on heterogeneous catalyt..

Surface chemistry is the study of processes that occur at the interface of two bulk phases. The bulk phases can be of the type solid-gas, solid-liquid, liquid-gas and liquid-liquid. There is no interface between gases because of their complete miscibility. The bulk phase can be solutions or pure co..

. Catalysis involves reactions where catalysts are used. Catalysts are used to accelerate the rate of reaction. Catalysts accelerate the rate of reaction by providing an alternate reaction pathway in which the activation energy is lower. Homogenous catalysis involves catalysts w..
