“…13 The particle size distribution of the carbon nanospheres of the synthesized samples S1-S4 are shown in Fig. 4 a-d respectively, all the samples are a mix of nano and micro particles, the presence of agglomerated particles might be due to Ostwald ripening mechanism and the strong interatomic interaction between the nanospheres, due to the higher solubility of the crystals, Ostwald mechanism is responsible for the larger growth of crystals from smaller size particles, 16 , S3 has the largest mean particle size diameter of 98 nm, and S1 has the smallest mean particle size diameter of 76 nm, due to the quantum confinement effect S1 has the smallest particle size diameter and hence the largest Eg of 4 eV, and S4 has the largest mean particle size diameter and the smallest Eg of 3.4 eV, which can be used as a photocatalyst to degrade dyes like Methylene blue (MB) or Rhodamine B (RhB) in water, 17 the presence of nanorods might have affected the value of Eg. the lower concentration of the nanoparticles is suggested for S1 and S2 which explains the low intensity peaks of UV-VIS spectrum and this coincides with the results obtained by.…”

Pulsed liquid laser ablation is considered a green method for the synthesis of nanostructures because there are no byproducts formed after the ablation. In this paper, a fiber laser of wavelength 1.064 µm, peak power of 1 mJ, pulse duration of 120 ns, and repetition rate of 20 kHz, was used to produce carbon nanostructures including carbon nanospheres and carbon nanorods from the ablation of asphalt in ethanol at ablation speeds of (100, 75, 50, 10 mm/s). The morphology, composition and optical properties of the synthesized samples were studied experimentally using FESEM, HRTEM, EDS, and UV-vis spectrophotometer. Results showed that the band gap energy decreased with decreasing the ablation speed (increasing the ablation time), the minimum mean particle size of the synthesized samples was 76 nm at an ablation speed of 100mm/s, while the maximum mean particle size was 98 nm at ablation speed of 50 mm/s, the nanospheres were agglomerated to form larger spherical nanoshapes. All the synthesized carbon nano colloids exhibited a blue-green PL emission. It was concluded that the presence of carbon nanorods has an effect on the optical properties of the synthesized nanospheres.

“…The functional groups of MNBC are the main factor for the remediation of contaminants. For example, biochar has negatively charged ion and heavy metals are positively charged cation so it makes a strong electrostatic bond in close proximity which help in removal of heavy metals from soil and water [91]. Organic contaminants like PAHs, phthalic acid esters, estrogen contaminants, and ionizable organic contaminants are remediated from soil and aquatic system by the hydrophobic interactions, pore filling, H-bonding, π-π electron donor-acceptor interactions, and electrostatic attraction [92].…”

Magnetic nanobiochar (MNBC) is a sort of nanobiochar that has been enhanced with magnetic qualities. MNBC is made from a variety of feedstocks, including wood chips, agricultural waste, municipal sludge, animal manure, and other organic waste. These feedstocks are pyrolyzed at various temperatures to produce biochar, which is then mixed with magnetic precursors to create MNBC. Crystallinity, high porosity, specific surface area, and great catalytic activity are a few of the dynamic properties of MNBC. The major purpose of this review paper is to characterize MNBC, using the various biochar synthesis methods and how bulk biochar is converted into MNBC with their high-value applications discussed here.

Nowadays, environmental pollution has become a critical issue for both developed and developing countries. Because of excessive industrialization, burning of fossil fuels, mining and exploration, extensive agricultural activities, and plastics, the environment is being contaminated rapidly through soil, air, and water. There are a variety of approaches for treating environmental toxins, but each has its own set of restrictions. As a result, various therapies are accessible, and approaches that are effective, long-lasting, less harmful, and have a superior outcome are extensively demanded. Modern research advances focus more on polymer-based nanoparticles, which are frequently used in drug design, drug delivery systems, environmental remediation, power storage, transformations, and other fields. Bioinorganic nanomaterials could be a better candidate to control contaminants in the environment. In this article, we focused on their synthesis, characterization, photocatalytic process, and contributions to environmental remediation against numerous ecological hazards. In this review article, we also tried to explore their recent advancements and futuristic contributions to control and prevent various pollutants in the environment.
