Zinc Oxide (ZnO) nano-superstructures (NSSs) have attracted intense research interests due to their large surface areas and unique properties. In this work, we report an original approach to synthesize ZnO NSSs in a one-step manner with a hydrothermal method. The crystalline structures and growth mechanism can be understood by surface energy calculations. The reaction kinetics was investigated ...

Ultrathin cobalt phosphate (CoHPO4 · 3H2O) nanosheets are successfully synthesized by a one pot hydrothermal method. Novel CoHPO4 · 3H2O ultrathin nanosheets are assembled for constructing the electrodes of supercapacitors. Benefiting from the nanostructures, the as-prepared electrode shows a specific capacitance of 413 F g(-1), and no obvious decay even after 3000 charge-discharge cycles. Such...

Cadmium is an extremely toxic metal, which even in low levels is harmful to the human body, animals and also plants. Human manufactures such as cadmium-nickel batteries and pesticides, plastic, make the earth polluted with cadmium; therefore removal of the cadmium Water is vital for human and animal. Scientists use different methods for cadmium removal including adsorption, precipitation, i...

It is pertinent to realize that scientific research indicates the most promising method for producing H2 photo electrochemical water splitting through a anode. Cobalt-doped SrTiO3 (Co-SrTiO3) composite nanostructures were created in this study via hydrothermal synthesis. The impact of cobalt concentration change on Co-SrTiO3 has been identified using morphological, structural, and research. Sur...

This study investigated the influence of ZnO nanostructures on dye adsorption to increase the photovoltaic conversion efficiency of solar cells. ZnO nanostructures were grown in both tree-like and nanorod (NR) arrays on an AZO/FTO film structure by using a hydrothermal method. The results were observed in detail using X-ray diffraction, field-emission scanning electron microscopy (FE-SEM), UV-v...

Spherical materials with yolk-shell structure have great potential for a wide range of applications. The main advantage of the yolk-shell geometry is the possibility of introducing different chemical or physical properties within a single particle. Here, a one-step hydrothermal synthesis route for fabricating amphoteric yolk-shell structured aluminum phenylphosphonate microspheres using urea as...

Several samples of mesoporous silica were prepared via sol-gel chemistry in the presence of CTAB as template with variation of stirring intensity and aging time, ratios of CTAB/SiO2 and NH4OH/H2O in synthesis mixture. Effects of aging temperature, hydrothermal treatment and ter-Butanol addition to the synthesis mixture on the textural properties of obtained samples were also studied. Results of...

a series of copper and cobalt substituted nanospinel ferrites have been synthesized by the hydrothermal method. these compounds were characterized by ft-ir, xrd, edx, sem and vsm techniques. all of the synthesized nanospinel ferrites were found to be highly efficient and magnetically recoverable in the solvent-free synthesis of substituted 2,6-(2-hydroxybenzyl)-phenols (trisphenols). a wide ran...
