“…And the porous structure, in which the multiple scattering of light could appear, would enhance the utilization of light of ATC‐P10 . The bandgap energy is obtained by the intercept method according to the formula Ahv = K ( hv – E g ) 2 , . Compared with P25 (3.3 eV) and ZTOF‐1‐P10 (3.0 eV), the band‐gap energy of the ATC‐P10 (Figure b) was calculated to be about 2.9 eV.…”

A series of Ag-enhanced TiO 2-x /C composites (Ag/TiO 2-x /C composites) with metal-organic frameworks (MOFs) as precursors were prepared, and their photocatalytic activities were evaluated by the UV-light driven photodegradation behaviors of methyl blue (MB). The as-obtained samples were characterized by several techniques such as SEM, XRD, N 2 -adsorption, XPS, UV/Vis spectrophotometry and UV/Vis diffuse-reflectance spectra.

“…When the specific surface area and porosity of the catalysts increase, more light will be received, and the porous structure can lead to multiple scattering of light and improve the utilization of light . According to the formula Ahν = K ( hν – E g ) 2 , the bandgaps of these samples were obtained by the intercept method. The bandgaps of PTC‐P6 (2.9 eV), PTC‐P8 (2.8 eV), PTC‐P10 (2.7 eV) and ZTOF‐1‐P10 (3.0 eV) are smaller than that of P25 (3.3 eV), while the bandgap of PTC‐P4 (3.4 eV) is larger than that of P25.…”

A series of Pt modified TiO2–x/C composites with higher specific surface area were obtained by using a Zn‐Ti heterometallic metal‐organic framework (MOF) as the precursor. The photocatalytic activities of these composites were studied by methylene blue (MB) as a representative organic pollutant. The chemical composition and porosity of these composites can be adjusted by changing the pyrolysis temperature. Among them, the sample being pyrolyzed at 1000 °C (PTC‐P10) showed excellent photocatalytic performance, and its rate constant of degradation of MB was higher than that of ATC‐P10 (Ag modified TiO2–x/C composites) due to the rapid capture of electrons and the expansion of the photoresponse range caused by Pt modifying. This work represents a novel approach towards Pt modified TiO2–x/C composites as photocatalysts.

For the PCO process to be effective, several variables such as light intensity, amount of catalyst, temperature, pH, UV irradiation time, and initial pollutants concentration must be optimized (Shahrezaei et al 2012).…”

Petrochemicals are derived directly or indirectly from petroleum. During the production of petrochemicals, various refractory and toxic pollutants are generated, which are harmful to the aquatic system. These pollutants are genotoxic, carcinogenic, and teratogenic. Although these pollutants are harmful, only a limited number of studies have been performed on their removal or degradation. Conventional wastewater treatment techniques are not efficient in removing these pollutants from wastewater. Therefore, the scientific community is now putting up efforts to make the Advanced Oxidation Processes (AOPs) more efficient. The main aim is to produce very reactive species (especially hydroxyl radicals, HO˙) in water by the AOPs. This leads to the degradation or transformation of the contaminants or pollutants, resulting in complete mineralization. The most studied AOPs for the degradation of petrochemical wastewater pollutants are photocatalytic oxidation (PCO), ozonation, catalytic oxidation, catalytic ozonation, and electrochemical advanced oxidation processes. This chapter specifically discusses the various AOPs used to remove specific pollutants and chemical oxygen demand (COD) from petrochemical wastewater treatment to meet discharge standards.
