“…It was observed that the absorption edge of P-CeO2-TiO2 showed a gradual red shift with increase in synthesis temperature from 400 °C to 600 °C and hence decreasing the bandgap value from 2.98 to 2.93 eV. Another study by Sha et al [346] showed a gradual decrease in the bandgap energy of SCS synthesized CeO2-TiO2 modified with plots [349] ). [346] with permission from Elsevier, copyright 2020.…”

“…Several reports show that CeO2-TiO2 heterojunction are efficient towards photocatalytic applications. However, the visible photocatalytic activity can be further enhanced by modifying this heterojunction with metal or non-metal atoms by increasing the electron-hole separation and by extending energy range of photoexcitation [346,347] .…”

“…This ternary interface improved the photoinduced lifetime of electrons and enhanced the rate of carrier transport. In a study by Sha et al, [112] CeO 2 -TiO 2 hybrids were designed using NiÀ P to enhance the photocatalytic properties of oxide hybrid. The enhanced properties were attributed to band edge narrowing and subdued recombination tendency of photo-induced e À -h + pairs.…”

Global warming and its cause and effects have necessitated the researchers to look beyond fossil and its derivatives. The scalability of CO2 reduction and H2 energy is one of the most enigmatic questions asked by the calamitous environmental changes happening across the world such as bushfires in Australia, Amazon and California or the melting of Arctic and Antarctic ice scalps. Thus, the research fraternity is keen to elevate the efficiency of CO2 reduction and H2 energy to the extent that the good chemical livestock produced by CO2 conversion and H2 fuel would become principal energy resources. In this quest, photocatalytic pathway envisions the environmentally benign protocol to bring about CO2 reduction and H2 production. Photo‐reduction of CO2 and H2 generation via photocatalytic water splitting by utilizing oxide based heterostructured photocatalysts are the promising approaches to carry out CO2 mitigation and H2 production efficiently ascribed to the advanced optoelectronic and structural superiority of oxides photocatalysts as discussed in this review.

Constructing heterostructures is a promising strategy to improve the photoelectrochemical (PEC) performance of photoanodes in PEC water‐splitting systems. The effect on PEC performance is dependent on the deposition conditions of the overlayer in the heterostructured photoanode. Herein, the deposition condition of the antimony selenide (Sb2Se3) overlayer by adjusting the duty cycle and cycle number during pulse‐reverse electrodeposition. This aims to assess its impact on the PEC characteristics of the Sb2Se3 overlayered titanium dioxide (Sb2Se3/TiO2) nanotube photoanode. Adequate pulse‐off time in the duty cycle ensures sufficient permeation of deposition electrolyte into the inner wall of TiO2 nanotube, leading to uniform Sb2Se3 deposition. On the other hand, an excessive cycle number negatively affects PEC performance, as Sb2Se3 agglomeration blocks the pores of the TiO2 nanotube. Consequently, the Sb2Se3/TiO2 nanotube photoanode, when fabricated with the optimal pulse‐off time and cycle number, exhibits enhanced PEC performance. This is due to efficient charge transfer/separation facilitated by the p–n heterojunction and improved light absorption. These insights offer valuable guidance in choosing the appropriate fabrication processes for heterostructured photoanodes in efficient PEC water‐splitting systems.
