“…Higher photoelectrochemical activity was also obtained for GO/In 2 S 3 /TiO 2 nanorods used as photocatalysts for photoelectrochemical water splitting [227]. The improved performance was attributed to the larger surface area, visible light absorption and improved carrier transport because of additional defect states [92,[228][229][230].…”

TiO2 is seen as a low cost, well-known photocatalyst; nevertheless, its sluggish charge kinetics does limit its applications. To overcome this aspect, one of the recent approaches is the use of its composites with graphene to enhance its photoactivity. Graphene-based materials (nanosheets, quantum dots, etc.) allow for attachment with TiO2 nanostructures, resulting in synergistic properties and thus increasing the functionality of the resulting composite. The current review aims to present the marked progress recently achieved in the use of TiO2/graphene composites in the field of photocatalysis. In this respect, we highlight the progress and insights in TiO2 and graphene composites in photocatalysis, including the basic mechanism of photocatalysis, the possible design strategies of the composites and an overview of how to characterize the graphene in the mixed composites. The use of composites in photocatalysis has also been reviewed, in which the recent literature has opened up more questions related to the reliability, potential, repeatability and connection of photocatalytic mechanisms with the resulting composites. TiO2/graphene-based composites can be a green light in the future of photocatalysis, targeting pollution remediation, energy generation, etc.

“…32 H. Esmaili et al reported photo-electrochemical water splitting with naphthalene diimide functionalized graphene nanoribbons as the water oxidation layer on TiO 2 films. 33 These results strongly suggested that the interaction of TiO 2 and graphene nanoribbons can have enhanced photocatalytic activity due to effective charge separation between interfaces of graphene/TiO 2 surfaces. However, photocatalytic nanoribbons generally used in the oxide state, which has many oxygen-derived modification groups existing on the surface of GNRs obtained by oxidative cleavage and function as electron trapping sites.…”

“…The oxygen evolution reaction (OER), as shown in Equation (2), is an anodic reaction and it is a rate-limiting reaction because it utilizes four electrons to form O 2 . So, the overall efficiency of water splitting depends on OER, and a significant effort has been dedicated to synthesizing OER photocatalysts [ 2 ]. Similarly, several catalysts have been developed for the electrochemical water splitting [ 3 , 4 , 5 ].…”

The rapid depletion of fossil fuels and environmental pollution has motivated scientists to cultivate renewable and green energy sources. The hydrogen economy is an emerging replacement for fossil fuels, and photocatalytic water splitting is a suitable strategy to produce clean hydrogen fuel. Herein, the photocatalyst (PdO.TiO2) is introduced as an accelerated photoelectrochemical oxygen evolution reaction (OER). The catalyst showed significant improvement in the current density magnitude from 0.89 (dark) to 4.27 mA/cm2 (light) during OER at 0.5 V applied potential. The as-synthesized material exhibits a Tafel slope of 170 mVdec−1 and efficiency of 0.25% at 0.93 V. The overall outcomes associated with the photocatalytic activity of PdO.TiO2 demonstrated that the catalyst is highly efficient, thereby encouraging researchers to explore more related catalysts for promoting facile OER.
