“…The isotherms can be classified as type IV, revealing the mesoporous structure of various prepared samples. 18 , 19 From the adsorption branch of the isotherm, a slight increase in the specific surface area was observed by calcination at 700 °C (the specific surface for ACW, ACW-calcined, and SnO 2 /ACW-calcined samples were found to be 50.05, 56.89, and 56.45 m 2 g –1 , respectively). Table 1 indicates that the pore volume of ACW-calcined and SnO 2 /ACW-calcined samples exhibits wide pore volume compared to ACW sample, and the pore size distribution confirms the existence of mesopores and macropores 20 as shown in Figure 3 (inserted Figure).…”

Activated carbon granules present in our household filters used in water purification are significant waste. Activated carbon waste (ACW) was ground to a fine powder, then impregnation of SnO 2 on ACW was performed under mild conditions followed by calcination of SnO 2 -ACW at 700 °C for 2 h, producing a SnO 2 -ACW hybrid composite. This hybrid composite material was used in the preparation of electrodes for supercapacitor and capacitive deionization applications. The electrochemical performance of the electrodes was investigated by using cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance spectroscopy. Calcination and addition of SnO 2 contributed to an obtained electrode with a high specific capacitance of 30.46 F g –1 in a solution of 1 M Na 2 SO 4 compared to the original ACW (0.122 F g –1 ) and calcined-ACW (1.42 F g –1 ) at an actual current of 1 mA. This electrode was also investigated for water desalination through the capacitive deionization technique and exhibited an electrosorption capacity of 6.44 mg/g compared to the commercial AC (8.9 mg/g) so it is a highly promising and economic electrode.

“…Among these metal oxides, TiO 2 is most attractive photocatalyst for the degradation of untreated pollutants. [24][25][26][27][28] Thus, TiO 2 is used in industries as colouring agents in paints, papers and cosmetics, etc., and it is also widely used as a photocatalyst material. 29 In the present study, TiO 2 has been selected as a photocatalyst for the decolourization of (Methylene Blue) MB dye which is mostly used in the dying process.…”

A simple one-step biosynthesis route has been adopted for the synthesis of high crystalline phase pure anatase TiO2 nanoparticles. The structural conformation and functional group analysis of the synthesized nanoparticles were made through X-Ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR), respectively. The optical property and the band gap were estimated by using UV-Visible diffuse reflectance spectroscopy (UV-DRS). The surface morphological properties of the anatase TiO2 nanoparticles were confirmed using Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) and the size of the synthesized nanoparticles are 8 nm. The element analysis was evaluated by using EDS and X-ray photoelectron spectroscopy (XPS). The photocatalytic activity of the prepared sample was investigated by the decolourization of Methylene blue dye under UV and solar light irradiation. The maximum dye removal efficiency of 99.2% was observed for solar light irradiation. Besides, the prepared samples also exhibit excellent antibacterial activity against Klebsilla Pneumoniae and Streptococcus Pneumoniae. The antibacterial activity for the synthesized TiO2 nanoparticles show maximum zone of inhibition (23.5 mm). Thus, the biogenic property of the bioprocessed TiO2 nanoparticles is a potential material for environmental and biomedical applications. [Formula: see text]
