Colloidal Fe-doped ZnO nanocrystals: Facile low temperature synthesis, characterization and properties

Effect of ionic size compensation by Ag+ incorporation in homogeneous Fe-substituted ZnO: studies on structural, mechanical, optical, and magnetic properties

“…There are various types of physical and chemical methods for synthesizing samples such as simple vapor transport and chemical co-precipitation method, 27 solid state reaction method, 28 radio-frequency (rf) magnetron sputtering technique, 29 facile low temperature synthesis, 30 sol-gel method, [31][32][33] etc. Among these methods, sol-gel method is a simple, inexpensive and high yield method providing uniform homogeneous powders.…”

Sintesis ZnO-SiO2 dan Aplikasinya pada Fotokatalisis Degradasi Limbah Organik Fenol dan Penurunan Kadar Cd(II) secara Simultan

“…Limbah industri yang banyak mengandung fenol diantaranya, industri kimia, petrokimia, farmasi, tekstil, dan baja [1]. Diantara berbagai semikonduktor baru dipelajari, seng oksida (ZnO) dapat digunakan dalam dekomposisi polutan organik karena tinggi fotosensitivitas, karakteristik mekanik sangat baik, rendah biaya, dan aman bagi lingkungan [2][3][4]. ZnO memiliki pita valensi tepi yang terjadi sekitar 3,37 eV, lubang yang sangat kuat sebagai agen oksidasi dan mampu mengoksidasi molekul organik serta menghasilkan radikal hidroksil dalam air [5].…”

Nano-sized Fe-metal catalyst on ZnO–SiO2: (photo-assisted deposition and impregnation) Synthesis routes and nanostructure characterization

“…Among various semiconductors studied, ZnO has been identified as a promising host material and proved to be the most suitable catalyst for widespread environmental applications because of its high photosensitivity, excellent mechanical characteristics, low cost and environmentally safe nature [4,5].…”

“…Another disadvantage of ZnO is that charge carrier recombination of photo-generated electron/hole pairs occurs within nanoseconds and the photocatalytic activity is low [4,[6][7][8]. Therefore, it is necessary to improve its visible-light activities by extending its absorption threshold from the UV light region to the visible light region and also reduce the recombination of photo-generated electron/hole.…”
