“…COD removal confirms the destruction of the organic materials in the TDW and the color reduction [64]. The percentage of COD removal obtained for NSAC (1)(2)(3)(4)(5) samples are: 35.7, 40.3, 46.1, 54.5, 61.3, and 70.1%, respectively, for 120 min irradiation. The NSAC5 catalyst was found to be the most efficient one.…”

“…The bands of NSAC (1-5) were of higher energy, when compared to pure NiO. The NSAC (1-5) samples displays higher optical absorption; this is due to addition of intermediate energy bands in NSAC (1)(2)(3)(4)(5), and these intermediate energy levels decrease the effective band gap of the NiO and make it more receptive in the UV region of the electromagnetic spectrum.

“…They also exhibit hysteresis loop, corresponding to the mesopore structure behavior of Type-IV isotherm. Thus, the AC and NSAC (1)(2)(3)(4)(5) samples are a blend of Type-I and Type-IV isotherms as defined by IUPAC classification. AC uptake of nitrogen adsorption reached as high as 136.63 cm 3 /g, whereas lowest nitrogen adsorption of 33.47 cm 3 /g was obtained for NSAC5.…”

A B S T R A C TNickel oxide nanoparticles supported activated carbon (NSAC) photocatalyst was successfully prepared using a cost-effective microwave irradiation method. The earned UV lightsensitive NSAC composites were characterized using powder X-ray diffraction, Fourier transform infrared spectroscopy, High-resolution scanning electron microscope with energydispersive X-ray analysis, X-ray photoelectron spectroscopy, and Brunauer-Emmett-Teller surface area analyzer. Optical properties of NSAC composites were investigated using UVVis diffuse reflectance spectroscopy and photoluminescence spectroscopy, which exposed prolonged light absorption in UV light region and hold better charge separation capability, respectively, as compared to pure NiO. The photocatalytic activity was tested by the degradation of textile dye waste water (TDW) under UV light irradiation. Chemical oxygen demand of TDW was calibrated before and after the photocatalysis experiment under UV light to evaluate the mineralization of wastewater. The results demonstrated that NSAC composites showed imposing photocatalytic enrichment over pure NiO. The coordinated blending of the oxygen vacant sites, structural defects of NiO along with electron transmission capacity, and presence of surface oxygen on AC has led to the lasting light absorption, delayed charge recombination, and sustenance, which favor the enrichment of the photocatalytic activity of NSAC.

“…Recently, adsorption has been regarded to be very effective and attractive because of its operation under mild conditions and no need of oxidant, active catalyst, and irradiation [8,9]. Therefore, adsorption with carbon nanotubes, activated carbon (AC), biomass, and metallic-organic frameworks (MOFs) has been actively studied for the removal of dye molecules from water [10][11][12][13][14][15]. However, adsorbents with high adsorption capacity, structural integrity, low cost and facile recyclability are required for the practical operations or commercial applications.…”

Adsorptive removal of bulky dye molecules from water with mesoporous polyaniline-derived carbon

Polyaniline-derived carbon (PDC) was obtained via pyrolysis of polyaniline under different temperatures and applied for the purification of water contaminated with dye molecules of different sizes and charge by adsorption. With increasing pyrolysis temperature, it was found that the hydrophobicity, pore size and mesopore volume increased. A mesoporous PDC sample obtained via pyrolysis at 900 °C showed remarkable performance in the adsorption of dye molecules, irrespective of dye charge, especially in the removal of bulky dye molecules, such as acid red 1 (AR1) and Janus green B (JGB). For example, the most competitive PDC material showed a Q 0 value (maximum adsorption capacity) 8.1 times that of commercial, activated carbon for AR1. The remarkable adsorption of AR1 and JGB over KOH-900 could be explained by the combined mechanisms of hydrophobic, π-π, electrostatic and van der Waals interactions. 597
