Simple hydrothermal method

In this paper, we reported NO2 sensors based on the ZnO nanorods with different sizes fabricated using a simple hydrothermal method without surfactants. The sensors offered the excellent response and sensitivity to NO2 at very low concentrations as low as 100 ppb. The influence of the size of the ZnO nanorods on the NO2 sensing response was focused.

This paper presents a simple process of fabricating a superhydrophobic carbon steel surface with high water repellence and good corrosion resistance. The steel surface was covered by thin ZnO layers via various methods of sol-gel method, hydrothermal synthesis, and electrochemical deposition, then further functionalised with methyl trichlorosilane.

Hydroxyapatite (HA) is one of the most important calcium phosphate minerals due to its application in orthopaedics and dentistry. The applications of the synthesized HA powder depend upon the morphology of the HA. In this research, hydroxyapatite crystal nanowires are synthesized by simple hydrothermal method from clamshells.

In this paper, a very simple procedure was presented for the synthesis of WO3 nanoparticles by hydrothermal treatment at 180 ◦C for 48 h using sodium tungstate and hydrochloric acid as starting materials. As-obtained WO3 nanoparticles were characterized by field emission electron microscopy (FE-SEM), X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy (EDS).

This paper presents an investigation on the performance of ZnO nanorod (ZNR)-based piezoelectric nanogenerators (PENGs). ZNRs on the ZnO seed layer coated double-sided flexible polyethylene terephthalate (PET) at different molar concentrations (0.01, 0.05 and 0.1 M) were synthesized by controlling the aspect ratio (length/diameter) of ZNRs, that are closely related to the piezoelectric output potential voltage using a simple hydrothermal method.

In this research, we present the ZnO nanorods synthesized through the simple route of the hydrothermal method. The ZnO nanorods were developed through the application of only zinc acetate Zn(CH3 COO)2 and ammonia solution, NH4 OH, in the hydrothermal process at 1500 C for 10 hours. The size of the ZnO nanorods was defined as approximately 300 nm in diameter and 1-2 µm in length. The fabrication of sensors was achieved through drop-coating of synthesized ZnO nanorods on Al2 O3 substrates integrated with Au electrodes.

Oxidative exfoliation followed by chemical reduction is an effective method to synthesize reduced graphene oxide (rGO). However, it is challenging to synthesize large scale high quality rGO by a simple and inexpensive method. In this study, rGO materials were synthesized by a scalable hydrothermal method, where the temperatures were controlled to obtain different morphology and quality of rGO.

In this work, we study a semiconductor-based photocatalyst MoO3 synthesized using three simple techniques, including as-prepared, hydrothermal and microwave-assisted methods. The obtained samples were characterized using X-ray diffraction (XRD), and Raman spectroscopy. We found a better crystallinity in the nanoparticles synthesized by the microwave-assisted method in comparison to those synthesized by the other methods.
