“…Many scholars have reported improving the photocatalytic activity of TiO2 via heteroatom-doping [19], surface modification [20,21], the loading co-catalysts [22][23][24], and the formation of heterojunctions [25][26][27][28]. Among these methods, the transition-metal cation modification of TiO2 is an effective strategy for enhancing the visible light absorption ability and improving the photocatalytic properties of TiO2 [29,30].…”

“…Among the various photoanode materials, TiO 2 is considered one of the most explored candidates for water oxidation, thanks to its extraordinary stability, eco‐friendly, high corrosion resistance, and high photocatalytic performance in the UV region. All of these features make TiO 2 one of the most widely‐ investigated semiconductor photoanodes in photoelectrochemical cells . However, it has been observed that TiO 2 is associated with some drawbacks, hindering its utilization in practical PEC water splitting systems.…”

Point defects play important and crucial roles in the design of high performance photocatalysts. We report on the electrochemical fabrication of black TiÀ Mo-NiÀ O nanotubes as a promising electrode material for solar-assisted water splitting. The ternary TiÀ Mo-NiÀ O catalyst was annealed in hydrogen atmosphere to induce point defects in the material to enhance its conductivity, charge carriers density, and performance. The effect of annealing duration on the performance of ternary TiÀ Mo-NiÀ O nanotube films was investigated. The hydrogenannealed nanotubes showed enhanced optical characteristics in the visible spectrum, which can be related to the formation of defect states upon hydrogen annealing. The 10 h-annealed sample showed an exceptionally enhanced photocurrent density of ∼ 10 mA/cm 2 with a remarkable open-circuit voltage of ∼ À 1.0 V Ag/AgCl under AM 1.5G illumination. This improved photocurrent is in agreement with the obtained 75 % incidentphoton-to-current-conversion-efficiency (IPCE), confirming the improved photoactivity of the hydrogen-treated mixed oxide nanotubes.

“…The N-doped TiO2 photoelectrode performed water splitting with a maximum photoconversion efficiency of 8.35% at 0.3 V bias potential illuminated by xenon lamp illumination at an intensity of 40 mW cm -2 103 . Many other reports came to similar conclusions that their N-doped TiO2 absorbed both UV and visible light and showed improved PEC performance [104][105][106] .…”

Photoelectrocatalysis (PEC) incorporates electrochemical techniques with photocatalysis (PC) to facilitate the separation of the photoelectron-hole produced at semiconductor nanoparticles, leading to enhanced photocatalytic efficiency for various applications. Due to its inherently low cost, non-toxicity and chemical stability, titanium dioxide (TiO2) based PEC devices are considered the most promising system for chemical engineering such as pollution degradation and fuel generation, and PEC sensing. In an attempt to bridge fundamental research and practical applications in chemical engineering and sensing, we herein systematically review recent advances in these PEC systems of different scales. More importantly, we offer a series of rational strategies including cell design, application of electric field photoelectrode morphology manipulation and bandgap engineering to enhance the performance of TiO2-based PEC devices and accelerate the commercialization of the TiO2-based PEC technology in chemical engineering.
