Bismuth oxide nanoparticles were characterized by Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), and UV-Visible Diffuse Reflectance Spectroscopy (UV-DRS). The FTIR spectra obtained implies that the bismuth oxide nanoparticles of the three ratios contain Bi-O-Bi and Bi-O groups indicating its successful formation. XRD diffractogram suggests that the synthesized bismuth oxide nanoparticles form the α-Bi2O3 crystalline phase for ϕ<1 and ϕ>1; meanwhile a mixture of α-/β- Bi2O3 phases for ϕ=1. The SEM image illustrates that bismuth oxide nanoparticles form pebble shapes with the ratios in the order of increasing particle sizes of ϕ>1, ϕ=1, and ϕ<1. The UV-DRS results show that the bismuth oxide with ϕ<1, ϕ=1, and ϕ>1 have respective band gap energies of 2.76 eV, 2.72 eV, and 2.78 eV. The evaluation of the photocatalytic activity of the three bismuth oxide samples shows bismuth oxide with ϕ=1 has the highest photocatalytic activity in remazol black B and methyl orange dyes with rate constants 6.744 x 10-5 s-1 and 7.369 x 10-5 s-1, respectively.

TiO2 shows promising photocatalytic properties that can degrade organic pollutants such as dye under ultraviolet (UV) irradiation. However, TiO2 possesses some disadvantages such as a wide band gap and a high recombination rate of electron-hole pairs. Coupling TiO2 with various metal oxides can enhance photocatalytic properties. In this work, photodepositon (reduction of metal ions on TiO2) followed by the thermal oxidation method were used for the coupling of TiO2 with CuO, ZnO, or SnO2 under various methanol concentrations (25 vol% or 50 vol%) and deposition duration (1 h or 3 h) to observe the effect of these parameters on the photocatalytic degradation activity on Rhodamine B (RhB) dye (up to 90 min). The rate constant of the photodegradation reaction (k) has improved from 0.0141 min−1 (uncoupled TiO2) to 0.0151~0.0368 min−1. Overall, CuO/TiO2 and SnO2/TiO2 samples have shown similar photocatalytic properties (average rate constants of 0.0341 min−1 and 0.0327 min-1, respectively), and both performed better than ZnO/TiO2 in terms of RhB photodegradation (average rate constants of 0.0197 min−1). The difference in photocatalytic performance can be explained by the bandgap of metal oxides and their relative band positions with TiO2. Lastly, CuO/TiO2 (50 vol%, 3 h) and SnO2/TiO2 (50 vol%, 3 h) have shown the best photocatalytic properties respectively due to a longer deposition time and higher concentration methanol, resulting in more deposited materials.

Capturing and utilizing of CO2 are more important than ever, both to reduce CO2 emission and to increase the economic value of CO2 derivatives. In this study, synthesis of metal-organic frameworks (MOFs) was conducted by combining Zn2+ metal nodes and 2-methylimidazolate ligand to form zeolitic imidazolate frameworks (ZIF-8) materials. ZIF-8 was synthesised with the addition of sodium chloride to modulate the crystal morphology during the in-situ synthesis, using either water or methanol as the solvent. According to the refinement of the X-ray diffraction pattern, the ZIF-8 materials were successfully prepared and have unit cell parameters that are reasonably close to the available standard. The formation of ZIF-8 is also confirmed by IR spectroscopy, which reveals the stretching vibration mode of Zn−N from the coordination between Zn2+ and 2-methylimidazolate ligand. The crystal morphology exhibits different shape, as observed in SEM and TEM studies, with the dominant shape being a rhombic dodecahedron. The interaction between ZIF-8 and CO2 was investigated via ex-situ IR spectroscopy, combined with several computational techniques such as density functional theory and molecular dynamics, to elucidate the nature of the CO2 binding sites.

The hydrothermal carbon (HTC) were prepared from low polymeric sugars and low concentration glucose under hydrothermal carbonization reactions without using dispersants. The composition and structure of the biochar produced were characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), Raman spectroscopy (Raman), and N2 adsorption-desorption, indicating that amorphous graphitic carbon was obtained. Experimental results from the static adsorption of Cr(VI)-contaminated wastewater showed that HTCP-2 exhibited the highest adsorption capacity for Cr(VI), with a maximum adsorption capacity of 22.62 mg.g−1.The adsorption Cr(VI), MB, and RhB by the synthesized biochar all conformed to the pseudo-second-order kinetic model and Freundlich isotherm, suggesting a multilayer chemical adsorption process. Additionally, the synthesized HTC surface is enriched with a significant amount of oxygen-rich functional groups, which also has good adsorption performance for cationic dyes. Furthermore, the test results of fluorescence, photocurrent, and impedance indicate that HTCP-2 possesses the ability to generate and separate photoinduced charge carriers. This implied that HTCP-2 can be used for the preparation of adsorption photocatalysts, which effectively remove environmental pollutants through the synergistic effect of adsorption-photocatalysis.

The existence of waste makes water unfit for consumption. Phenol waste is one example of waste that is often found. The toxic and corrosive nature of phenol is very dangerous for life, so its presence must be considered. The adsorption process was carried out using NiAl and ZnAl layered double hydroxides composites with biochar to eliminate the presence of phenol waste The adsorption process was carried out using NiAl and ZnAl layered double hydroxydes materials which were composited with biochar to eliminate the presence of phenol waste. NiAl-Biochar and ZnAl-Biochar composites were successfully prepared, as determined by XRD, FTIR, SEM, and BET analyses. NiAl layered double hydroxide surface area grew from 92.683 to 438.942 m2/g while ZnAl layered double hydroxide surface area increased from 9.621 to 58.461 m2/g. pHpzc of material is between 5.1 and 9.4. Optimal pH of NiAl and ZnAl layered double hydroxide is 3, optimum pH of NiAl-Biochar and ZnAl-Biochar is 5, and optimum pH of Biochar is 7. All kinetic and isotherm models for all materials were pseudo-second-order and Freundlich, respectively. NiAl-Biochar and ZnAl-Biochar have maximal adsorption capacities of 74.62 mg/g and 52.91 mg/g, respectively. The material's reusability indicates that NiAl-Biochar has superior qualities and may be reused for up to five cycles, followed by ZnAl-Biochar, NiAl layered double hydroxide, ZnAl layered double hydroxide, and Biochar.

Besides use of pomelo peels (agricultural residues) as a feedstock for the pyrolysis, to contribute to environmental sustainability, rice husk was used as a silica source for obtaining the silica support. From the result, it was found that non-catalytic pyrolysis of pomelo peels gave a bio-oil yield of 33.3 wt%. The catalytic pyrolysis with vanadium-modified silica decreased the bio-oil yields ranging between 27.2-33.1 wt%. This was due to the occurrence of the second reactions generated from the active sites on the catalysts, which leads to the conversion of bio-oil into gas products. For NS catalyst, increasing the amount of vanadium loading directly decreased the bio-oil yields and increased the gas yield. The variation of product phase distribution was not clearly observed for MS catalyst even with various vanadium loadings. In addition, NS catalyst exhibited higher efficiency in reducing the acid content in the bio-oil, and increasing the phenol content. The distinguished properties of the nanoparticles may be the main reason for these phenomena. Copyright © 2023 by Authors, Published by BCREC Group.

The solid mixture was washed until the pH of 2, then left at room temperature for 3 days. Physical properties of synthesized CSH were characterized using Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), wavelength dispersive X-ray fluorescence (WDXRF), Scanning Electron Microscope (SEM), nitrogen adsorption-desorption isotherm, and melting point test. It is concluded that the CSH were formed due to hydrolysis of fishbone-derived carbon in a moderately concentrated sulfuric acid solution of carbon-derived fishbone and crystallization into a fibrous octa calcium phosphate (OCP) form.
