The waste soot particles emitted from a diesel engine were studied as a dye adsorbent for water treatment. The input parameters were optimized using response surface methodology to achieve the maximum removal of dye methylene blue (MB). Experiments were conducted according to three‐level Box–Behnken Design with three factors time, pH, and initial concentration of dye in the solution. Further, analysis of variance analysis was carried out to find the level of significance of each parameter toward dye removal. Finally, for 0.05 g of diesel soot in a 50 ml solution, the maximum dye removal predicted was more than 99%. The basic medium (pH 12) found was favorable for the adsorption of MB. Also, 96% of detergent was removed in 60 min. Langmuir isotherm model and Pseudo‐second‐order kinetic model were most suitable for equilibrium and kinetic studies, respectively, for the removal of MB on diesel exhaust emission soot.

“…Hence, the soot particles are hazardous waste, which needs to be minimized. The minimization of diesel soot can be done using more efficient diesel engines and using exhaust after-treatment devices 23 . However, there exist still no method, that can bring down the diesel soot to zero.…”

The diesel soot (DS) coated non-woven fabric was studied for oil-water separation along with the adsorption of dyes, detergents, and pharmaceuticals. The DS coated non-woven fabric showed more than 95% separation efficiency and consistent repeatable performance during oil-water separation experiment. In addition to this, the DS coated non-woven fabric of 17.2 cm 2 area successfully adsorbed ~85%, 97%, and 100% methylene blue (MB) dye, ciprofloxacin, and detergent, respectively from their respective solutions within 30 min, which was not possible using uncoated non-woven fabric. The DS coated non-woven fabric was found to be hydrophobic with the contact angle of 140° which was almost invariant upto 60 °C. Hence, the DS coated non-woven fabric showed promising performance in the oil-water separation and adsorption applications.

“…DEES was found to have good hydrophobic property and used for the water−oil separation application [Figure 14A(i−iii)]. 75 Liang et al established a relationship between the wettability and chemical compositions of the soot particles produced through the incomplete combustion of candles. On the basis of the site of formation by the upper or lower flame, they explored the hydrophobic property of CS.…”

Herein, we provide a possible description for the isolation/fabrication of nanocarbons from freely available global pollutant waste as black-carbonaceous-soot particulates known as black carbon (BC). It is important to mention here that BC contains many different types of nanocarbons, which have routinely been formed during combustion and were further admixed with air, and therefore enhancing the possibility of global warming. Nevertheless, the different composition and burning condition of fuel results in the emission of different-sized−shaped soot particulates. BC particulates are generally divided into two categories, i.e., indoor and outdoor BC. A possibility has been discussed here to develop some more easily accessible isolation methodologies for the extraction of nanocarbons from BC, explicitly with the expectation to use them for fruitful purposes. Additionally, it will also contributing in improving the overall air quality. In particular, this review summarizes the spectroscopic and microscopic identifications of nanocarbons isolated from the different types of indoor and outdoor BC particulates. Further, in subsequent sections, we have discussed their possible applications, like sensing, bioimaging/biological activity, adsorption, photocatalysis, energy storage devices, agricultural uses, photonics, superamphiphobic material, etc.
