Oxidation occur s when a substance poses an electron and combines with another substance. In some cases this reaction is initiated by having the atoms excited by a wave lenght of light such as the Ultraviolet. Thae presence of a catalystic surface like TiO may assist the process.
Photochemical oxidation is therefor the reaction of a chemicla cjhange in a substance which causes it to lose electrons which is initiated by light.
A common example is photochemical smog which is caused by hydrocarbons and NOx reacting under the influence of UV light

∙ 12y agoRegarding the so called Redox set of chemical reactions, the process of chemical reduction is the opposite of the process of chemical oxidation.
What is different between the Reduced methane H2CH2 (CH4) and the Oxidized carbon dioxide O=C=O is - the reduced molecule has no Oxygen whereas the oxidized molecule has no Hydrogen.
Interspersed throughout the above is electron transfer - paramount in importance to Photosynthesis.
