Creation of unsafe squanders and harmful gas exhaust and smokes into the earth because of the fast pace of industrialization and the resultant byitems have influenced nature. For the treatment of a wide range of natural and lethal squanders different ordinary advances are utilized, for example, adsorption, organic oxidation, compound oxidation and cremation. Supercritical water oxidation (SCWO) has been proposed as an innovation fit for crushing an extensive variety of natural dangerous wastes. It has been attracting consideration because of its capacity to crush a substantial assortment of high-hazard wastes coming about because of weapons disarmament and complex mechanical synthetic handling. In the scope of convergence of 1–20% of natural poisons, SCWO is far less expensive than cremation oractive carbon treatment. In parallel, the quick development in nanotechnology has picked up a lot of enthusiasm for the environmental uses of nanomaterials. The high surface territory to a mass proportion of nanomaterials can enormously enhance the adsorption limits of sorbent materials. Because of its diminished size, the surface territories of nanomaterials develop exponentially for an indistinguishable thickness from the breadth shrivels. In view of their decreased size and vast radii of ebb and flow, the nanomaterials have a surface that is particularly responsive (basically because of high thickness of low-planned particlesat the surface, edges, and vortex). These one of a kind properties can be connected to corrupt and search poisons in water and air [1]. Nanomaterials in different shapes/morphologies/frames significantly affect water and air quality in a natural environment [2]. Likewise, a few normal and designed nanomaterials have additionally been demonstrated to have solid antimicrobial properties, including chitosan, silver nanoparticles (nAg), photograph synergist TiO2 , and carbon nanotubes (CNT) [3–7]. Nanotechnology is likewise utilized for discovery of pesticides and substantial metals (e.g., cadmium, copper, lead, mercury, arsenic, etc.). Besides, nanomaterials have improved redox and photocatalytic properties [8–10]. Functionalization process is connected onnanomaterials by covering or substance alteration with a specific end goal to (1) enhance surface and optical properties, (2) evade total, and (3) dispense with association among nanomaterials and biological substance. For instance, doping with a fitting dopant can improve photocatalytic movement and cause red-move in the bandgap of TiO2 that prompts to have the ability to assimilate light in the visible range [11]. Accordingly, hybrid nanocomposites are manufactured by impregnating or covering the fine particles onto strong particles of bigger size to beat thelimitations of NPs.
