“…Subsequently, the photogenerated electrons (holes) transfer from the CB of p-diamond (VB of ZnO) to the CB of ZnO (VB of p-diamond) under electric field located at the interface between ZnO and BDD, and the probability of the recombination of electron-hole pairs are significantly reduced. Consequently, the highly efficient electron-and hole-related redox processes would occur for the degradation [20].…”

The ZnO nanorod arrays (NRs) have been fabricated on p-type boron-doped diamond (BDD) substrate by hydrothermal method. It was demonstrated that the density and diameter of the ZnO NRs can be effectively controlled by adjusting the reactant concentration. Photocatalytic activity of the fabricated ZnO NRs/p-BDD heterojunction was investigated for the degradation of methyl orange dye and the results indicated that diameter and density of ZnO NRs play a very important role in photocatalytic degradation. Furthermore, the ZnO NRs/p-BDD heterostructure photocatalysts are easily recycled and reused.

“…Combining oxide or nitride semiconductors with diamond substrates attracts great attention mainly motivated by the lack of efficient p-type doping in the oxides (nitrides) and n-type doping in diamond, respectively. The complementary configuration of these wide band gap materials with p-type boron-doped diamond and n-type oxides (ZnO, TiO 2 ) and n-type nitrides (GaN, AlN) has been most widely studied recently [10][11][12][13][38][39][40][41][42][43][44][45][46][47][48][49][50][51][52][53]. Generally, growth of oxides and nitrides films on diamond remains challenging due to the high difference in the thermal expansion coefficients and large lattice mismatch (leading to structural imperfections) and relatively less efficient performance of devices.…”

“…In recent decade, ZnO-related nanostructures and the corresponding nanooptoelectronic devices have been extensively studied [54]. The heterojunctions based on ZnO nanostructures were generally grown on silicon [55], GaN [56], sapphire [57], and diamond [11,39,41]. Experimentally, the performances of the diamond-related biosensor electrodes have been significantly improved by modifying ZnO nanorods (NRs) (Figure 13) synthesized using the sol-gel method [10].…”

In the last decade, besides the breakthrough of high-rate growth of chemical vapor deposited single-crystal diamonds, numerous nanostructured diamond films have been rapidly developed in the research fields of the diamond-based sciences and industrial applications. The low-dimensional diamonds of two-dimensional atomic-thick nanofilms and nanostructural diamond on the surface of bulk diamond films have been theoretically and experimentally investigated. In addition, the diamond-related hybrid nanostructures of n-type oxide/p-type diamond and n-type nitride/p-type diamond, having high performance physical and chemical properties, are proposed for further applications. In this review, we first briefly introduce the three categories of diamond nanostructures and then outline the current advances in these topics, including their design, fabrication, characterization, and properties. Finally, we address the remaining challenges in the research field and the future activities.

“…Among the important class of semiconductors, ZnO has UV light‐responsive properties, high chemical stability, low toxicity, low cost, and high oxidative efficiency and attracted considerable attention intrinsic . Moreover, ZnO has higher electron mobility (200‐300 cm 2 V −1 s −1 ) compared with TiO 2 (0.1‐4.0 cm 2 V −1 s −1 ) and exhibits a higher efficiency than TiO 2 in the photocatalytic degradation of some dyes.…”

To overcome the drawbacks of fast charge recombination and the limited visible‐light absorption of semiconductor photocatalysts, N ion irradiation is used to enhance photocatalytic performance of ZnO nanowires. Compared with as‐grown ZnO nanowires, the photocatalytic performance of ZnO under dose of 5 × 1015 cm−2 was efficiently improved because of the bandgap energy decreasing and the introduction of oxygen vacancies defects. On one hand, the reduced bandgap energy improves the easy transfer process of electrons and holes, thus improving the charge separation efficiency, and visible‐light absorption. On the other hand, N ion irradiation increases oxygen vacancy defects and hinders the recombination of photo‐excited electrons and holes. This study has certificated that ion irradiation is an efficient way and created a new insight on the enhancement of photocatalytic activity.
