“…Several research outputs about the photocatalytic performance and reaction conditions of pollutant degradation for OIHPs are summarized in Table 2. Compared with other photocatalytic applications of OIHPs, photocatalytic degradation of pollutants was less attractive, since nearly all degradation processes of OIHPs should be implemented in the liquid phase generally, and pollutants such as rhodamine B (RhB), [65] Methylene blue (MB), [86] and Eosin B [87] exist in wastewater. It is no doubt that the key challenge of photocatalytic degradation of pollutants is the aquatic solution as reaction environment in general.…”

Over the past few decades, organic–inorganic halide perovskites (OIHPs) as novel photocatalyst materials have attracted intensive attention for an impressive variety of photocatalytic applications due to their excellent photophysical (chemical) properties. Regarding practical application and future commercialization, the air–water stability and photocatalytic performance of OIHPs need to be further improved. Accordingly, studying modification strategies and interfacial interaction mechanisms is crucial. In this review, the current progress in the development and photocatalytic fundamentals of OIHPs is summarized. Furthermore, the structural modification strategies of OIHPs, including dimensionality control, heterojunction design, encapsulation techniques, and so on for the enhancement of charge‐carrier transfer and the enlargement of long‐term stability, are elucidated. Subsequently, the interfacial mechanisms and charge‐carrier dynamics of OIHPs during the photocatalytic process are systematically specified and classified via diverse photophysical and electrochemical characterization methods, such as time‐resolved photoluminescence measurements, ultrafast transient absorption spectroscopy, electrochemical impedance spectroscopy measurements, transient photocurrent densities, and so forth. Eventually, various photocatalytic applications of OIHPs, including hydrogen evolution, CO2 reduction, pollutant degradation, and photocatalytic conversion of organic matter.

“…Elanthamilan et al [38] used M-type magnetic strontium hexaferrite (SrFe 12 O 19 ) microspheres and showed 90.2% MB degradation efficiency with higher recyclability. Fu et al [39] used iron (II) carbonate mineral as a catalyst and reported that 99.7% of MB was degraded in 480 min at a pH of 7.0, an H 2 O 2 dosage of 122.38 mM, and a reaction temperature of 25 • C using 2.5 g/L of mineral. Chahar et al [40] reported the use of Mg 2+ -substituted Co-Zn nanoferrite particles of the composition Co 0.5 Zn 0.5 MgFeO 4 having good magnetic properties and achieved complete MB photodegradation in one hour of visible light irradiation.…”

This study presents an efficient way to degrade methylene blue (MB) present in water via photodegradation using H2O2 as an oxidant in the presence of UV irradiation and without the use of a catalyst. The reaction variables, employed to evaluate the performance of the photodegradation process using the UV/H2O2 system, were the amount of H2O2 in the reacting solution and the initial concentration of methylene blue. The degradation of methylene blue in the presence of H2O2 was not observed during agitation in darkness. The degradation time decreased as the H2O2 concentration increased after the ideal concentration was reached. At this stage, as it began to scavenge the generated hydroxyl radicals, the rate of degradation became inversely proportional to the concentration of H2O2. An increase in the quantities of MB and H2O2 improved the degradation efficiency because the oxidation process was aided by using the appropriate amount of H2O2 and an ideal length of UV light exposure. The experimental data obtained were well-fitted to zero-order reaction kinetics based on the high values of the correlation coefficient. It is believed that the OH radicals (OH●) generated during the breakdown of H2O2 and the generated O2●− species attack the MB molecules and produce MB radicals (MB●). These MB radicals further experience oxidation and convert to intermediates and finally to CO2 and H2O. The UV/H2O2 system proved to be quite efficient for the photodegradation of methylene blue without the use of any solid catalyst. This UV/H2O2 system can be employed in the degradation of other organic pollutants in industrial wastewater.
