“…The polar or dispersive component of surface energy which is attributed to London forces (dispersion, orientation and induction) [2,9]. The polar component includes the orientation and induction forces of the dipoles which can be attributed to the formation of hydrogen bonds [2,10]. There are different approaches for estimating the value of the solid-liquid interfacial energy (γls) from the measured contact angles.…”

“…Due to their simplicity of fabrication and excellent efficiency, copper oxides have resurfaced as an important topic in low-cost solar cell applications (20 percent in Cu2O based cells). Because of the tiny band gap in its crystal structure, it has photocatalytic and photovoltaic capabilities [1][2][3]. According to recent studies, thin-film hetero-junction solar cells, such as Glass / F: SnO2 / CdS / CuO / Ag [2] or FTO / ZnO / Cu2O / Au [4], have shown increased solar energy conversion efficiency.…”

The adhesive characteristics of sol-gel copper oxide (CuO) film surfaces at annealing temperatures ranging from 350 to 550°C were examined in this work. Hydrophobic properties of these oxide film surfaces were studied by contact angle measurements. The surface energy was calculated from contact angle data using harmonic mean method. The structural, morphological and chemical analysis of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared (FTIR). The increase in annealing temperature induces a reduction in the hydrophilic properties of the films (adhesive properties). The rise in the hydrophobicity of the CuO surface has been claimed to be explained by a change in interfacial tension. The FTIR spectroscopy analysis revealed that the increase in the annealing temperature eliminates activated neutral species (hydroxyl groups) reacting with the surface of the sample responsible for the wettability. SEM analysis showed that the morphology of the samples is nanostructured containing agglomerates of various forms, a few hundred nanometers in size, randomly dispersed across the surface. The enhanced roughness of the produced film is primarily responsible for the increased hydrophobicity of the films. The XRD data reveal that the films are highly textured and that increasing the annealing temperature induces better layer crystallization and confirms the development of copper oxide CuO.

“…of the two materials, the mismatch phenomenon at the interface endows the heterojunction with a lot of novel properties, which have been attracting much research on heterogeneous materials and devices. In the past, heterojunctions have made tremendous contributions to photocatalysts [151,152,153], solar cells [154], photovoltaic applications [155], photoelectrochemical applications [156,157,158], diode devices [159], etc. The unique properties of a heterojunction also make it an effective and practical candidate for gas sensors.…”

A gas nanosensor is an instrument that converts the information of an unknown gas (species, concentration, etc.) into other signals (for example, an electrical signal) according to certain principles, combining detection principles, material science, and processing technology. As an effective application for detecting a large number of dangerous gases, gas nanosensors have attracted extensive interest. However, their development and application are restricted because of issues such as a low response, poor selectivity, and high operation temperature, etc. To tackle these issues, various measures have been studied and will be introduced in this review, mainly including controlling the nanostructure, doping with 2D nanomaterials, decorating with noble metal nanoparticles, and forming the heterojunction. In every section, recent advances and typical research, as well mechanisms, will also be demonstrated.
