“…The matched energy band of g‐C 3 N 4 and TiO 2 has been fruitful to couple them for constructing the heterojunction, which is considered an alternative to obtain maximized photocatalytic performance in comparison to individuals [31,32] . Therefore, TiO 2 /g‐C 3 N 4 composite have been extensively researched in recent years, and most published works have shown that the coupling of g‐C 3 N 4 with TiO 2 is of greater importance benefiting from both g‐C 3 N 4 and TiO 2 properties [31–36] . Although the majority of these studies concentrate on the treatment of volatile chemical compounds, phenols, and organic pigments.…”

“…Therefore, the photocatalytic activity of TiO 2 has not yet been achieved as per expectation. Several strategies, such as doping with metals [22] or non‐metal, [23] coupling with visible‐light active semiconductors, [24–27] etc have been addressed to tune its photocatalytic properties. Doping reduces the energy band gap, while coupling with other semiconductors enhance the separation rate of electron–hole pair charge through the transfer of electrons and holes between the semiconductors [28] .…”

The impact of alkaline hydrothermal treatment on the structure and morphology of Degussa P25 was evaluated. The modification results in a larger surface area, which improves 2,4‐dichlorophenoxyacetic acid (2,4‐D) adsorption capacity and has a remarkable effect on the 2,4‐D photocatalytic degradation. The 30 % mod. TiO2/g‐C3N4 and 50 % mod.TiO2/g‐C3N4 composites were made by combining the treated Degussa P25 with g‐C3N4 at mass ratios of 30 % and 50 %. Using XRD, SEM, EDX, BET, UV‐vis DRS, and PL, the synthesized materials were physically characterized. When compared to their pure components, the composites show a longer “lifetime” of charge carriers and a reduced energy band gap. The 2,4‐D degradation under visible light irradiation (λ>400 nm) was used to assess their photocatalytic activity. The influence of pH and 2,4‐D initial concentration were investigated. The enhanced 2,4‐D degradation efficiency of more than 80 % is ascribed to the cooperative photocatalytic action of mod.TiO2 and g‐C3N4. Both ⋅OH, O2⋅− radicals and h+ were the ROS dominating the degradation of 2,4‐D under investigated experimental circumstances. The 2,4‐D photocatalytic degradation follows pseudo‐first order kinetics. The findings of this work indicate that Degussa P25/g‐C3N4‐based photocatalysts may be employed, depending on the pH conditions, in the wastewater treatment.

In the recent years, photocatalytic hydrogen production using nanomaterials‐based photocatalysts have gained extensive attention. Various metal oxides have been widely explored in the photocatalytic hydrogen generation. It is interesting to prepare the efficient photocatalysts for photocatalytic hydrogen generation reactions. In present work, we used simple synthetic procedure for the preparation of cobalt oxide nanoparticles (Co3O4 NPs). The Co3O4 NPs were prepared using precipitation method. The surface structural features such as topological surface morphology was checked by scanning electron microscope. Presence of Co and O elements were authenticated by energy dispersive X‐ray spectroscopy. The phase purity or formation of Co3O4 NPs was evaluated by powder X‐ray diffraction approach. The optical band gap of the obtained Co3O4 NPs was determined by using ultraviolet‐visible spectroscopy. Furthermore, we have explored the synthesized Co3O4 NPs as photocatalyst for photocatalytic hydrogen production reaction. The obtained results exhibited good photocatalytic behavior of Co3O4 NPs was towards hydrogen production. The hydrogen amount of 4565 μmol.g−1 was produced using Co3O4 NPs as photocatalyst. The reusability of the Co3O4 NPs photocatalyst was also checked and obtained results showed that Co3O4 NPs is stable for reusability.

MXene has indeed gained significant attention in recent years as a promising photocatalyst for various applications, including photocatalytic degradation of pollutants. MXene possesses several unique physical and chemical properties that make it suitable for such applications, including its uniform planar structure, strong metal conductivity, effective functional groups, and numerous derivatives. These properties contribute to the excellent photodegradation performance and long‐term stability exhibited by MXene‐based photocatalysts compared to other photocatalysts. MXene‐based composites, which are formed by incorporating MXene with other materials, demonstrate even better photodegradation activity due to their abundant active sites and porous structure. One crucial factor influencing the photodegradation performance of MXene‐based photocatalysts is the presence of active functional groups on the surface of MXene. These functional groups play a significant role in the photocatalytic process and contribute to the overall efficiency of the catalyst. To provide a broader understanding of MXene‐based photocatalysts, the physicochemical properties of MXene are briefly described in this review. This includes its structural characteristics, electrical conductivity, and the presence of functional groups. This review also investigates the physical and chemical synthesis routes for preparing MXene, both in its natural state and as composites with other materials. These synthesis methods are essential for tailoring the properties of MXene‐based photocatalysts to meet specific requirements. Finally, the review discusses future work and challenges in MXene‐based photocatalysis. This field holds great promise for addressing environmental concerns and improving the degradation of organic compounds. However, further research is needed to optimize the synthesis methods, enhance the photocatalytic efficiency, and explore the practical applications of MXene‐based photocatalysts.
