“…As we know, ZnO is an n‐type semiconductor with excellent optical and electrical properties. It can be used for many applications including photocatalysts, solar cells, and transparent conducting layer . As gas sensor, the sensitivities of ZnO‐based materials are still low, especially to detect some chemically stable gases, such as benzene, CH 4 , H 2 .…”

ZnO is often used as gas sensor. In order to increase the sensitivity of the sensors, many methods are used to change the gas-sensing properties. In this paper, ZnO was synthesized by hydrothermal method using Zn (NO 3 ) 2 as a zinc source. Sodium lauryl sulfate (SDS) and polyvinylpyrrolidone (PVP) were added into the system to control microstructure and surface morphology of ZnO nanoparticles. The SDS was kept constant, and the PVP was changed. The morphology and composite were investigated by field emission scanning electron microscopy and X-ray diffraction.The chemical valence of the elements was determined by X-ray photoelectron spectroscopy. The sensing properties were investigated at different PVP components. It is found that ZnO has a red zinc structure. When the m SDS :m PVP = 1:1, the sensing sensitivity is best. The mechanism of equivalent matching structure optimization performance is proposed.

XRD and XPS indicate that the SDS and PVP addition will not affect the crystal structure. The experiments show that the sensitivity and selectivity of ZnO increase when m SDS :m PVP = 1:1.

“…Due to its excellent optical and electrical properties, large band gap (3.37 eV) and exciton energy (60 MeV), ZnO is expected to be important in applications such as sensing, light-emitting diodes, photocatalysts, solar cells and transparent conducting layers. [13][14][15][16][17] As we know, the photocatalytic efficiency is relative to the surface chemical reaction and electron-hole recombination. If the course of electron-hole recombination is too fast, the surface chemical reaction will not occur.…”

Semiconductor materials are often used as photocatalysts. In order to increase the photocatalytic ability, rare earths are usually added to change the properties of materials. In this paper, we report that Ce:ZnO nanoparticles were synthesized and their photocatalytic properties researched. Wastewater containing methyl blue was used as the object of investigation. Ce:ZnO samples were synthesized using a simple chemical method. Four samples were obtained: three containing Ce concentrations of (1, 2 and 3) % (w/%) and one of pure ZnO. Optical properties of the samples were investigated with UV-Vis. X-ray diffraction (XRD) and field-emission scanning electronic microscopy (FESEM) were employed to examine the chemical composition and microstructures. It was found that the size of ZnO crystallites is suppressed after Ce-doping. Further, the samples were used as efficient photocatalysts for a photocatalytic degradation of methyl blue. It was observed that Ce-doped ZnO nanoparticles exhibited excellent photocatalytic properties. The degradation ability increased with the increasing Ce concentration. For the sample of 3 % of mass fractions of Ce-doped ZnO, a complete photodegradation was observed after 60 min.
