Nanomaterial-based catalysts are usually heterogeneous catalysts broken up into metal nanoparticles in order to enhance the catalytic process. Metal nanoparticles have high surface area, which can increase catalytic activity.
Nanotechnology is the manipulation of matter with at least one dimension sized from 1 to 100 nanometers (nm). At this scale, commonly known as the nanoscale, surface area and quantum mechanical effects become important in describing properties of matter.
The World Health Organization declared in 2014 that air contamination caused around 7 million deaths in 2012. This new technology could be an essential asset to this epidemic. The three ways that nanotechnology is being used to treat air pollution are nano-adsorptive materials, degradation by nanocatalysis, and filtration/separation by nanofilters.
The discovery of a highly ordered crystal nanostructure of amorphous C-S-H gel and the application of photocatalyst and coating technology result in a new generation of materials with properties like water resistance, self-cleaning property, wear resistance, and corrosion protection. [10]
In chemistry, plasmonic catalysis is a type of catalysis that uses plasmons to increase the rate of a chemical reaction. [1] A plasmonic catalyst is made up of a metal nanoparticle surface (usually gold, silver, or a combination of the two) which generates localized surface plasmon resonances (LSPRs) when excited by light.

Research in photocatalysis again paused until 1964, when V.N. Filimonov investigated isopropanol photooxidation from ZnO and TiO 2 ; [4] [9] while in 1965 Kato and Mashio, Doerffler and Hauffe, and Ikekawa et al. (1965) explored oxidation/photooxidation of CO
