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.
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
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.
Benito Mussolini, dictator of Fascist Italy (left), and Adolf Hitler, dictator of Nazi Germany (right), were fascist leaders.. Fascism (/ ˈ f æ ʃ ɪ z əm / FASH-iz-əm) is a far-right, authoritarian, and ultranationalist political ideology and movement, [1] [2] [3] characterized by a dictatorial leader, centralized autocracy, militarism, forcible suppression of opposition, belief in a ...
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Generic hydrolysis reaction. (The 2-way yield symbol indicates a chemical equilibrium in which hydrolysis and condensation are reversible.). Hydrolysis (/ h aɪ ˈ d r ɒ l ɪ s ɪ s /; from Ancient Greek hydro- ' water ' and lysis ' to unbind ') is any chemical reaction in which a molecule of water breaks one or more chemical bonds.
