Historically, The wear of material can be traced to very early periods of human history. Lenardo Devinici is known to have had an interest friction but he was characteristically well a head of his time, and consistent interest in friction and wear awaited the further development of machines.

Some of phenolic compounds like chlorophenols can cause serious environmental problems. In particular, these compounds were introduced into the environment in the waste streams of several industrial operations, such as, pulp bleaching with chlorine, water disinfection or even waste incineration. Therefore the applications for metal oxide nanoparticles have been used to increase the photocatalytic property by influencing generation and recombination of the charge carriers under light.
