The organic dyes that have been added to water by various industrial effluents possess a serious threat to the environment due to their mutagenic character. TiO2 has been widely employed as a photocatalysis for the degradation of these dyes. However, a non-metal doped TiO2 can be a promising candidate for the advanced treatment of industrial wastewater containing organic dyes. In this work, we have prepared and tested different boron-doped TiO2 photocatalysts to examine the effect of boron addition on the photocatalytic activity of TiO2. The various boron precursors used are boric acid (BA), boron oxide (BO), and boron nitride (BN), through which Boron is formulated and is doped through a single-step sol-gel method. The prepared nanocomposites are characterized using various characterization techniques, such as Field Emission Scanning Electron Microscopy (FESEM), Transmission electron microscopy (TEM), ultraviolet-visible (UV-Vis) and Raman spectroscopy, X-ray diffraction (XRD), Fourier Transform Infrared (FTIR) spectroscopy, photoluminescence, and X-ray Photoelectron Spectroscopy (XPS) analysis. UV light of wavelength 365 nm has been used for studying the photocatalyst behavior. Both rhodamine-B (RhB) and industrial wastewater samples have been studied for degradation kinetics. The boron-doped TiO2 nanocomposites show a high level of dye degradation (>95%) with RhB dye and (>63%) with industrial wastewater samples. Further, TiO2-BA composites in both the cases showed maximum dye degradation compared with other boron nanocomposites with an enhancement in the efficiency of (>13%) over a pure phase of TiO2.
各种工业废水中添加的有机染料具有诱变特性，对环境造成严重威胁。TiO2作为光催化剂已被广泛应用于这些染料的降解。然而，非金属掺杂TiO2可以成为含有机染料工业废水深度处理的有希望的候选者。在这项工作中，我们制备并测试了不同掺硼的TiO2光催化剂，以考察硼的加入对TiO2光催化活性的影响。硼的前驱体有硼酸(BA)、氧化硼(BO)和氮化硼(BN)，硼是通过单步溶胶-凝胶法制备和掺杂的。利用各种表征技术，如场发射扫描电子显微镜(FESEM)、透射电子显微镜(TEM)、紫外可见(UV-Vis)和拉曼光谱、x射线衍射(XRD)、傅里叶变换红外(FTIR)光谱、光致发光和x射线光电子能谱(XPS)分析，对所制备的纳米复合材料进行了表征。用波长为365 nm的紫外光研究了光催化剂的行为。对罗丹明- b (RhB)和工业废水样品的降解动力学进行了研究。硼掺杂TiO2纳米复合材料对RhB染料和工业废水样品的染料降解率分别为>95%和>63%。此外，与其他硼纳米复合材料相比，这两种情况下的TiO2- ba复合材料都表现出最大的染料降解能力，比纯TiO2相的效率提高了(>13%)。

Ferric tannate (TA-Fe3+) has the potential to transform ammonium (NH4+) and nitrite (NO2−) into nitrogen gas (N2) through adsorption and catalysis. Few reports have given detailed account of different adsorption behavior for NH4+ and NO2−, which is important to develop the potential of the material. TA-Fe3+ was synthesized here and its performance as an adsorbent/catalyst for the simultaneous removal of NH4+ and NO2− from water was investigated. Results confirmed the adsorption and catalysis capability of TA-Fe3+ toward NH4+ and NO2−: (1) Following a 24 h adsorption and redox, the concentrations of NH4+ and NO2− in the mixed solution decreased from initial values of 10.71 and 7.14 to 4.28 and 1.64 mmol/L, respectively, and 0.41 mmol/g of N2 was produced with a maximal N2 yield rate of 0.072 mmol/[g·h]. The N2 yield was about 144 times that in the absence of TA-Fe3+; (2) intermediate products such as nitrous oxide (N2O) and nitrate (NO3−) were not detected; and (3) Raman spectrum analysis identified the site of Fe–O bond to be the center of adsorption and catalysis. Moreover, there were interesting findings: (1) TA-Fe3+ exhibited significantly distinct adsorption behavior toward NH4+ and NO2−. External diffusion and internal diffusion exerted a key influence on the adsorption toward NH4+ and NO2−, respectively; NH4+ was adsorbed on TA-Fe3+ in the form of monolayer, and NO2− in the forms of both monolayer and multilayer; (2) TA-Fe3+ was easily regenerated with water; and (3) adsorption toward NO2− was the rate-determining step of the catalytic reaction. These findings will provide valuable enlightenment for the further work to reveal the adsorption and catalysis mechanisms of TA-Fe3+.

Methylisothiazolinone (MIT) is a commonly used bactericide in wastewater treatment. Residual MIT in wastewater can lead to high environmental risks and toxicity. In this work, an emerging material MXenes has been introduced into the heterogeneous electro-Fenton catalysts to degrade MIT. Ti3C2Tx@Fe3O4, V2CTx@Fe3O4, and Mo2CTx@Fe3O4 were assessed as catalysts for MIT removal. The reasons for the differences among the three catalyst effects were analyzed according to different characterization results. Mo2CTx@Fe3O4 exhibited the best catalytic activity for MIT degradation. At pH = 3, the removal rate of MIT and corresponding chemical oxygen demand of catalyst Mo2CTx@Fe3O4 were 93.41% and 62.46% after 120 min. Among the three catalysts, Mo2CTx@Fe3O4 had larger surface area and porosity. Mo2CTx@Fe3O4 had the highest surface iron content, which meant that Fe3O4 was more easily loaded on the surface of Mo2CTX. What is more, Mo2CTX had the strongest ability to accelerate the regeneration of Fe2+. The durability of Mo2CTx@Fe3O4 was also evaluated. After four cycles, the removal efficiency of MIT only decreased from 92.51% to 89%. This work supports the development of heterogeneous electro-Fenton catalysts and the degradation of MIT.
