Nanoparticles of ZnO2 were synthesized through sol-gel technique using zinc acetate and hydrogen peroxide in aqueous solution exposed to UV irradiation and dried at 100 degrees C. Using electron microscope techniques, X-ray ...

In this report, the photocatalytic and electrochemical activity of ZnO and ZnO/CdO nanocomposites were determined. Pure ZnO and nanocomposite ZnO/CdO were prepared by a vapor to solid mechanism and were characterized by ...

Developing a device or material to detect volatile organic compounds (VOC) is no longer a challenge, despite its great interest. The difficulty is linked to developing a material that does not suffer from interferences, ...

Nanopartículas de argila bentonita, montmorilonita sódica, modificadas organofílicamente por octadecilamônio (Np-A) e nanopartículas de óxido de zinco (Np-ZnO) foram incorporadas em matriz de quitosana (Q) em diferentes ...

RESUMEN: Se estudió la reducción fotocatalítica de CO2 en presencia de agua (i.e., fotosíntesis artificial) empleando seleniuro de zinc (ZnSe) puro y modificado. El ZnSe se sintetizó mediante precipitación asistida con ...

(Eng) In this paper, samples of pure ZnO were prepared through solid - state chemical reaction, and optical spectral properties were investigated at low temperature. It was found that the strong broad ...

Desenvolver um material para detectar compostos orgânicos voláteis (VOC) não é mais um desafio, apesar de seu grande interesse. A dificuldade está ligada ao desenvolvimento de um material que não sofra interferências, como ...

ZnO is a versatile material used in numerous applications, such as antireflective coatings, transparent electrodes for solar cells, gas sensors, varistors and electro and photoluminescent devices. One of the most important ...
