The catalyst plays an extremely important role in the modern chemical industry, chemical production, scientists experiment and life activities, the catalyst can flourish. Nowadays almost more than half of chemical products are used in the production process where the catalyst. According to statistics, about 80% to 85% of the chemical production process using a catalyst, the purpose is to accelerate the reaction rate and improve production efficiency.
Application
Homogeneous catalyst
With the catalyst and reactants in one phase, the reaction is performed without the presence of a phase boundary, known homogeneous catalysis, heterogeneous catalysis can play catalyst is a heterogeneous catalyst. Molecules or ions that function independently in the active center of a uniform, high activity and high selectivity.
Heterogeneous catalyst
Heterogeneous catalysts of different phases present in the reaction (for example: a solid catalyst in the liquid reaction mixture) A simple heterogeneous catalytic reactions comprising a reactant or substrate, substrates; adsorbed in the surface of the catalyst, reactants key result is very fragile and lead to new keys are generated, but because the product key is not solid catalyst between, leaving the product appears. Table reactions are known to many different possibilities structural position adsorption reaction occurred.
