“…The carbonaceous species/ZnO nanocomposite was synthesized using an aqueous solution containing 0.01 M Zn­(NO 3 ) 2 ·6H 2 O, 0.01 M HMTA, and 0.002 M l -(+)-ascorbic acid by a microwave-assisted hydrothermal reaction at 180 °C for 30 min. The nanocomposite consisted of quasi-single crystalline ZnO regions and amorphous carbonaceous regions . Murugan et al reported the microwave-hydrothermal synthesis of carbon-coated LiMPO 4 (M = Mn, Fe, and Co) nanocomposite involving in situ carbonization of glucose.…”

Structural study and phase transition investigation in a simple synthesis of porous architected-ZnO nanopowder

“…Zinc oxide (ZnO) has been attracting a lot of attention for its various applications, such as semi-conductor devices, photo catalysts, pigments in paints and photovoltaic uses [1][2][3][4][5][6]. The well-known properties, such as the wide direct band-gap (3.3 eV), large exciton binding energy (60 meV), low cost, environmental friendly and abundance, make it a very interesting material.…”

“…There are a lot of parameters during synthesis that can affect the structure and microstructure of ZnO which are essential for their performance [17][18][19]. Thermal decomposition of zinc oxalate has been reported to produce porous and relatively high specific surface ZnO [6] which is especially interesting for gas sensing, photovoltaic or photocatalysis applications [21,22,12]. In the particular case of dye sensitized solar cells (DSSC), ZnO was reported as a good alternative of the conventional TiO 2 semiconductor material for the first time in 1994 [23].…”
