Photochemical catalysis:

In this type of catalysis, a catalyst is activated by light. The catalyst absorbs light energy and uses it to initiate or accelerate the reaction. An example of photochemical catalysis is the

  • use of a photocatalyst to split water into hydrogen and oxygen.

 

photochemical catalysis

some points on photochemical catalysisare given below:

  1. Photochemical catalysis is a form of catalysis that contains  the use of light to push a chemical reaction.
  2. Photochemical catalysis might be used to form reactive intermediates, such as
  • free radicals
  • and excited states, which can participate in a wide range of reactions.
  1. Photochemical catalysis might be used in
  • both homogeneous and heterogeneous systems,

liable on the

  • nature of the catalyst
  • and the reactants.
  1. Photochemical catalysis might be used in a broad range of reactions, including
  • organic synthesis
  • polymerization
  • and environmental remediation.
  1. The wavelength and intensity of the light used in photochemical catalysis can influence the rate and selectivity of the reaction.
  2. Examples of photochemical catalysts include
  • transition metal complexes
  • organic dyes
  • and semiconductor materials.
  1. Photochemical catalysis can be used to form highly reactive species that can take part in reactions that are challenging or impossible to achieve using conventional thermal catalysis.
  2. Photochemical catalysis is a zone of active research, with modern catalysts and applications being developed.
  3. Photochemical catalysis has the likely to be used in many areas, including
  • renewable energy
  • green chemistry
  • and medicine.
