Thermal decomposition is an endothermic chemical decomposition produced by heat that breaks the chemical bonds in the compound (Salavati-Niasari et al., 2008). The specific temperature at which an element chemically decomposes is the decomposition temperature. Nanoparticles are synthesized by decomposing metals at a particular temperature undergoing chemical reaction that produce secondary products.

Thermal decomposition: Thermal decomposition is the process of chemical decomposition of a compound at a specific temperature. In this method, nanoparticles are produced by decomposing the metals at their specific decomposition temperature (Salavati-Niasari et al., 2008; Abdullah et al., 2016; Adner et al., 2016; Ahab et al., 2016; Bartůněk et al., 2016; Glasgow et al., 2016; Khayati et al., 2016; Lee et al., 2016; Polteau et al., 2016; Sharifi et al., 2016; Sharma et al., 2016).

In the thermal decomposition method, the chemical reactions take place in a pressure-and temperature-controlled container such as an autoclave, in which the solvent reaches a temperature above its boiling point. If water is used as a solvent in this process, then this method is termed a hydrothermal process (Yu 2001, Rajamathi and Seshadri 2002). Chen and coworkers (2010) found the hydrothermal method useful in the synthesis of CuNPs of different sizes. Authors used sodium dodecyl benzene sulfonate (SDBS) as a surfactant for stabilization as well as to control the shape and size of the NPs. In this method, they found that the reaction temperature and SDBS play a significant role in shaping the final CuNPs.

Thermal decomposition processes can be geared towards facilitating further treatment or safe disposal of an organic feedstock, but can also be designed to facilitate the recovery of resources such as energy, carbon, nutrients, and/or metals. Thermal hydrolysis and advanced oxidation processes (AOPs) such as ozonation aim to make wet organic matter, usually sewage sludge, more biodegradable and are commonly applied as pretreatment to anaerobic digestion (Barber, 2016). Hydrothermal carbonization (HTC) (Danso-Boateng et al., 2013; Danso-Boateng, Holdich, et al., 2015; Danso-Boateng, Shama, et al., 2015), liquefaction (HTL) (Aida et al., 2016; Lu et al., 2017), and gasification (HTG) (Afif et al., 2011; He et al., 2014) aim to convert wet organic matter into charcoal, biocrude, or syngas, respectively. Hydrothermal oxidation (HTO) processes such as low pressure wet oxidation (LOPROX) (Blöcher et al., 2012) and supercritical water oxidation (SCWO) (Stendahl & Jäfverström, 2004) aim at complete destruction and conversion of wet organic matter to carbon dioxide. Pyrolysis (Bridle & Pritchard, 2004; Shepherd et al., 2016; Bai et al., 2017) aims to convert dry organic matter into charcoal and/or biocrude. Gasification (Rong et al., 2015) aims to convert dry organic matter into syngas. Incineration (Li et al., 2017) usually involves complete decomposition of organic matter by means of oxidation to carbon dioxide. Smoulder combustion (Yermán et al., 2015, 2017; Fabris et al., 2017) also aims at complete decomposition of organic matter but can be designed to yield pyrolysis products such as biocrude. Pyrolysis and HTL have been investigated with recovery of both nutrients and energy in mind, while the other processes have typically been targeted primarily towards recovering carbon in the form of charcoal or energy carriers.

Further, decomposition of anhydrous copper acetate and orange peel powder at 600 °C, causes the formation of CuO nanostructures (Equation 9). The gaseous products such as, water, carbon dioxide, and acetone are formed during the thermal decomposition process.[59]
