“…In the C 1s spectrum of NC/NiS-CeO 2 catalyst (Figure 4a), three main peaks were observed near 284.6, 286.1, and 288.2 eV, which can be attributed to C�C, C−S, and N−C�N bonds, respectively. 38 This is consistent with the FT-IR results. Moreover, the N 1s spectrum is shown in Figure 4b.…”

“…The degradation of AMX is basically completed in 40 min, while 1-g-C 3 N 4 only degrades 50% of AMX. This is due to the fact that thinner nanosheets can provide more reactive sites in the process of photocatalytic oxidation reduction [27]. Therefore, 3-g-C 3 N 4 was selected and compounded with CDs and agar to construct aerogel in the subsequent experiments.…”

Photocatalysis is one of the effective ways to degrade pollutant antibiotics. Agar is used as the adsorption module to provide abundant pore structure. Carbon dots (CDs) are selected as light energy conversion components. Graphitic carbon nitride (g-C3N4) is used as the main material of the catalyst. Agar/CDs/g-C3N4-functionalized aerogel with a unique 3D pore structure is assembled. The Agar/CDs/g-C3N4 aerogel shows the highest photocurrent density, which is 3.7 times that of agar, 2.4 times that of 3-g-C3N4 and 1.6 times that of Agar/g-C3N4 aerogel. Compared with 3-g-C3N4 and Agar/g-C3N4 aerogel, which can completely remove AMX after 75 min, Agar/CDs/g-C3N4 aerogel can degrade amoxicillin (AMX) completely after 45 min of illumination. The reason is that Agar/CDs/g-C3N4 aerogel has a larger specific surface area, richer functional groups, a wider spectral range, higher photocurrent density and better carrier migration and separation efficiency. It is a good strategy with which to combine the effects of each component in the ternary system for the efficient photocatalysis of organic pollutants.

“…In general, the generated hydroxyl radicals (•OH) (oxidation potential: 2.8 eV) [41] have high reactivity towards color-causing organic compounds [42]. Therefore, higher initial H 2 O 2 concentrations (5 and 8 mM) resulted in higher color removal efficiency rates.…”

UV/H2O2 is a commonly used advanced oxidation process for removing non-biodegradable organic compounds. However, additional efforts are needed to understand the relative significance of operational factors during the UV/H2O2. Here, we investigated the effect and specific contribution of crucial factors such as H2O2 concentration, UV intensity, and reaction time on the color and total organic carbon (TOC) removal efficiency in textile wastewater using the one-factor-at-a-time method and multi-layer perceptron (MLP) analysis. The results showed that color removal was enhanced with high H2O2 concentration, high UV intensity, and long reaction time. Overall, more than 99% removal of color was achieved by the UV/H2O2, utilizing the following parameters: H2O2 concentration of 5 mM, UV intensity of 26.6 W/m2, and reaction time of 180 min. On the other hand, the removal of TOC was increased by high H2O2 concentration and long reaction time, but not by high UV intensity. In the MLP analysis, the H2O2 concentration was identified as the primary factor affecting both color and TOC removal, accounting for 43% and 50% reduction of the color and TOC, respectively. Overall, this study helps to understand the relative importance of the most critical operating factors in treating actual textile wastewater by the UV/H2O2.
