“…Apart from temperature-induced transitions, it has also been reported that mechanical grinding at room temperature could irreversibly transform the tetragonal structure into a monoclinic structure [20]. Of the three BiVO 4 crystal structures, the monoclinic scheelite structure is the one that is most commonly used for photocatalysis because of its higher activity than the other structures [5].…”

Photoelectrochemical (PEC) water splitting, which is a type of artificial photosynthesis, is a sustainable way of converting solar energy into chemical energy. The water oxidation half-reaction has always represented the bottleneck of this process because of the thermodynamic and kinetic challenges that are involved. Several materials have been explored and studied to address the issues pertaining to solar water oxidation. Significant advances have recently been made in the use of stable and relatively cheap metal oxides, i.e., semiconducting photocatalysts. The use of BiVO 4 for this purpose can be considered advantageous because this catalyst is able to absorb a substantial portion of the solar spectrum and has favourable conduction and valence band edge positions. However, BiVO 4 is also associated with poor electron mobility and slow water oxidation kinetics and these are the problems that are currently being investigated in the ongoing research in this field. This review focuses on the most recent advances in the best-performing BiVO 4 -based photoanodes to date. It summarizes the critical parameters that contribute to the performance of these photoanodes, and highlights so far unresolved critical features related to the scale-up of a BiVO 4 -based PEC water-splitting device.

“…Among them, CuBi 2 O 4 is promising that could offer an exceptional positive onset potential of over 1.0 V versus RHE [48,76]. Indeed, this V OC is suitable for assembling with several photoanode made of BiVO 4 , Fe 2 O 3 etc for construction of a bias-free PEC device [21,77]. It is now important to further enhance the H 2 -evolving rate on this photocathode that readily reaches the level of ca.…”

Photoelectrochemical water splitting represents an attractive technological solution to harvest and then store the solar energy which is abundant but intermittent. It can be achieved by employing a photoelectrochemical cell, also called an artificial leaf. In order to construct viable photoeclectrochemical cells, efforts are being dedicated to engineer robust and efficient photocathodes for solar H 2 generation and photoanodes for solar water oxidation reaction. In this article, we discuss on the recent achievements and current perspectives in engineering of viable hybrid photocathodes. The state of the art on the design of a hybrid photocathode, its performance as well as the current understanding of its mechanistic operation will be first described. We then discuss on the technical strategies that are currently being developed to enhance the robustness and performance of a hybrid photocathode.

“…Among these materials, bismuth oxide compounds are prominent due to their special layer structure, which is beneficial to electron transfer in the interlayer Liu et al (2010). Besides, Bi 6s and O 2p orbitals can form a new valence band in a row above the original position through orbital hybridization, thereby effectively reducing the band gap and producing visible light absorption (Martinez Suarez et al 2015). Especially, bismuth oxyhalides, as a typical layerstructured photocatalytic materials, have been successfully prepared and applied in the water purification of organic pollutants (Ahern et al 2015;Henle et al 2007;Sun et al 2015;Wang et al 2011).…”

Three-Dimensional Bi $$_{5}$$ 5 O $$_{7}$$ 7 I Photocatalysts for Efficient Removal of NO in Air Under Visible Light

In this study, we report a flower-like Bi 5 O 7 I photocatalyst with a 41% gaseous nitride oxide (NO) removal efficiency under visible light through the in situ thermal treatment of the hierarchical architecture BiOI synthesized using a facile hydrothermal process. The UV-Vis diffuse reflectance spectroscopy and photocurrent experiments showed that the absorption band edge and photo-induced electron-hole pairs separation efficiency of Bi 5 O 7 I were negative than that of BiOI, whereas the as-prepared Bi 5 O 7 I exhibited excellent and stable visible light photocatalytic performance for NO removal as compared with original BiOI and P25. The results of electron spin resonance spectroscopy and density functional theory calculations suggested that the prominent visible light photocatalytic activity of obtained Bi 5 O 7 I has been attributed to the proper electron band structure which oxidizes the O 2 molecule to ·OH radicals with two electrons in the conduction band.
