**1. Introduction**

Recently, nanotechnologies and nanoscience have raised high hopes for a new potential industry revolution [1]. They produced materials of various types at nanoscales [2]. Nanotechnology is commonly used in many applications such as in industrial, medical, agriculture, aerospace, energy, automotive, and food. Many researchers have conducted to explore the field of nanotechnology. They focus to obtain to get the best nanomaterials with optimal mechanical and physical properties [3–5].

Nanomaterials are a wide class of materials that have a range of the dimension 1 nm-100 nm at least and they are made from nanoparticles [2, 6, 7]. There are several methods to synthesis a nanomaterial that was developed by many researchers.

There is chemical reduction [8, 9], chemical vapor deposition [10], photochemical [11], electrochemical [12], green synthesis [13], photochemical [11], Horizontal Vapor Phase Growth (HPVG) [14, 15], photochemical [11], microwave [16], sol–gel [17], and sonochemical [18]. One of the methods that successfully synthesized nanocomposite materials is the HPVG technique. HVPG was proven to be used to develop and able to produce material with various dimensional of nanostructures like Fe2O3 [19], Ln2O3 [20], Ag-TiO2 and SnO2 [21]. This technique offers some advantages like economical, reliable method, and less source material with high purity [22, 23]. HVPG technique is also capable to create nanomaterials with various shapes such as nanoparticles, nanotubes, nanorods, and triangular nanomaterials [14, 24–26]. They were evaluated to investigate the structure, chemical composition, hardness, and morphological behavior of the nanocomposite material [27]. Previous research about evaluated nanocomposite material synthesized with the HVPG technique is present in **Table 1**.

The applications of HVPG techniques on synthesized nanomaterials were varies among the different sectors. Tibayan et al. [23, 29] used HVPG to synthesized Ag/SnO2 nanocomposite materials that can be used in coating applications. The characterization process used UV filtering analysis to evaluate the UV blocking. The results showed that the UV can be blocked efficiently. Moreover, DFT analysis using An and Ag as the sample material also showed that the entire spectrum of UV light can be absorbed with the model. The summary of the previous research about synthesized nanomaterials using the HVPG techniques can be seen in **Table 2**.

Based on the explanation above, nanomaterials were synthesized by the HVPG technique and evaluated using several tests such as Scanning Electron Microscope (SEM), Energy-Dispersive X-ray Spectroscopy (EDX), X-Ray Diffraction Analysis (XRD), Density-Functional Theory (DFT), Applied Behavior Analysis (ABA),
