Therefore, an ever-growing demand for sustainable and environmentally-friendly energy technologies are prompting scientists to explore alternative approaches to reduce the carbon footprint. [2] Among the different sustainable energy sources, solar energy is an inexhaustible source of energy (173000 Terawatt (TW), almost 10 000 times of 17.7 TW, global energy consumption in 2020) and the largest currently available on earth with a ubiquitous distribution worldwide. [3] However, its decentralized and intermittent nature poses a great challenge to our energy needs. [4] Artificial photosynthesis, imitating a natural photosynthesis, where the harvesting of sunlight directly into chemical bonds (hydrogen, (H 2 ) fuel) is a highly promising approach to address the serious issue like air pollution, greenhouse gas emission, etc. Artificial photosynthesis by means of photoelectrochemical (PEC) water splitting has been studied extensively to split water using sunlight and semiconductor into oxygen (O 2 ) and H 2 , where the generated H 2 can be stored and transported to other energy conversion systems. [5] In recent years, PEC water splitting turned out to be an elegant and ecological way to generate clean H 2 fuel. Despite having mature and commercialized technologies, photovoltaic-electrochemical (PV-EC) water splitting systems have the most significant complications in PV designs. [6] In a photocatalytic (PC) water splitting system, on the other hand, both H 2 and O 2 are generated on the same surface of the PC particles, and hence in most cases, backward complex reactions like hydrogen oxidation reaction and oxygen reduction reaction occur quickly, lowering the solar to H 2 (STH) conversion efficiency. [7] In comparison to the PC system, the physical separation of oxidation and reduction species in PEC cells makes them more practical, effective, and safer. Moreover, the PEC cells have an electrode/electrolyte interface that performs simultaneous roles of light-harvesting and electrolysis in a single reactor. Consequently, the large-scale application of PEC cells is the most achievable, even at lower operating temperature as it opens up the opportunity to improve efficiency and reduce costs through the nature of its device structure. In particular, a recent assessment of its practicability has shown that the lifespan (i.e., stability), efficiency, and capital cost of The photoelectrochemical (PEC) cell that collects and stores abundant sunlight to hydrogen fuel promises a clean and renewable pathway for future energy needs and challenges. Monoclinic bismuth vanadate (BiVO 4 ), having an earthabundancy, nontoxicity, suitable optical absorption, and an ideal n-type band position, has been in the limelight for decades. BiVO 4 is a potential photoanode candidate due to its favorable outstanding features like moderate bandgap, visible light activity, better chemical stability, and cost-effective synthesis methods. However, BiVO 4 suffers from rapid recombination of photogenerated charge carriers that have impeded further imp...

“…WO 3 is considered as another candidate material for applications in electronics [ 7 , 107 ]. 1D WO 3 nanostructures (such as NRs, NWs and nanoneedles) have been used in photocatalytic applications [ 108 , 109 ], sensor switching devices [ 110 ], gas sensors [ 111 , 112 ] and UV photodetectors [ 2 ]. Because of the excellent performance of 1D WO 3 and BDD, it is worth combining them in 1D n-WO 3 /p-BDD heterojunction to provide new applications in electronics, especially at higher temperatures.…”

This review is mainly focused on the optoelectronic properties of diamond-based one-dimensional-metal-oxide heterojunction. First, we briefly introduce the research progress on one-dimensional (1D)-metal-oxide heterojunctions and the features of the p-type boron-doped diamond (BDD) film; then, we discuss the use of three oxide types (ZnO, TiO2 and WO3) in diamond-based-1D-metal-oxide heterojunctions, including fabrication, epitaxial growth, photocatalytic properties, electrical transport behavior and negative differential resistance behavior, especially at higher temperatures. Finally, we discuss the challenges and future trends in this research area. The discussed results of about 10 years’ research on high-performance diamond-based heterojunctions will contribute to the further development of photoelectric nano-devices for high-temperature and high-power applications.
