“…Then, in 2018, Kumar et al did an experiment in levofloxacin (LFC) degradation with Ag/Fe 3 O 4 bridged SrTiO 3 /g‐C 3 N 4 with superior performance; it was able to fully degrade in 90 minutes. LFC is a popular antibiotic that belongs to fluoroquinolone family that used in treating severe bacterial infections . SrTiO 3 also played the role in heavy metal reduction, such as Cr (VI) reduce to Cr (III).…”

Summary With the increasing demand and depleting trend of commercial energies, it has forced the researchers all over the world to accelerate research and development in the area of renewable energy. Currently, unique and interesting features of binary compounds have gained more attention by researchers, and it became a favourite research topic among various groups of researchers around this world. It was noticed that strontium titanate (SrTiO3) consists of several extraordinary properties that can apply for miscellaneous applications especially for energy storage, fuel cells, as well as to generate hydrogen fuel via photocatalysis process. Besides that, it was noticed that SrTiO3 can be synthesised in different pathways. The method of preparation and amount of precursors can affect the surface properties of SrTiO3. Thus, this article presents a critical review on how SrTiO3 synthesis methods affect its surface morphology and the applications of SrTiO3 in various fields.

Inspired by living systems, the construction of smart devices that can self-heal in response to structural damage is a promising technology for maintaining the high activity and stability of catalysts during heterocatalytic reactions. Here this study demonstrates an ingenious platform that enabled efficient persulfate (PS) activation for contaminant degradation via integrating a catalyst with photoactuation regeneration. Under irradiation, it is unambiguously confirmed that the collective properties of a tailored FeOOH@C N catalyst permit interfacial photoexcited electron transport from the photocatalyst substrate to needle-shaped FeOOH. This results in the simultaneous recovery of Fe(III) and optimization of the Fe(II)/Fe(III) ratio on FeOOH surface during PS activation process, so that the healed chemical structure ensures that subsequent PS activation remains unimpaired. Aqueous organic contaminant (bisphenol A) oxidation efficacy in this system is almost 20 times higher than for photo- or Fenton-oxidation alone. This work highlights the concept of catalyst regeneration for stable reactive species generation in solution, which represents alternative application of photocatalysis for practical environmental remediation. Further, the photoactuation healing approach can be expanded into various domains, such as material fabrication or chemical synthesis.

“…Among these, Advanced Oxidation Processes (AOPs) are considered as an effective method to remove non-biodegradable organic pollutants such as CIP from aqueous solution (Bobu et al, 2008). Recently, an innovative treatment technology based on sulfate radicals has gained great attention as an alternative to conventional AOTs for the oxidation of organic pollutants (Deng et al, 2013;Epold et al, 2015). Due to its relatively high stability, aqueous solubility and low cost, Persulfate is commonly used as a source of sulfate radicals in field application.…”

Being used in large quantities for some decades, antibiotics have been of little notice since their existence in the environment. Present study aims at investigating the optimization of Ciprofloxacin removal (CIP) in Thermally Activated Persulfate (TAP)/Aeration systems by Central Composite Design (CCD). The effect of operating parameters including initial pH, CIP concentration, Persulfate concentration and temperature on the removal process was investigated in order to find out the optimum conditions. Typically, high temperature, high Persulfate dose, and low initial CIP concentration increased the removal efficiency of CIP. At the tested pH range of 3-11, the highest removal occurred at pH 3.93. Finally, the effects of Mn3O4 Nanoparticles, N2 gas, and COD reduction in optimal condition were studied. Mn3O4 Nanoparticles and N2 gas in optimized conditions increased the removal efficiency from 93.41 to 90.1, respectively. The results showed that Thermally Activated Persulfate oxidation was the efficient process for the treatment of aqueous solution containing Ciprofloxacin due to the production of Sulfate radicals.
