In the present work, ZnO nanostructures were synthesized via wet chemistry method. The seeding solution was prepared from zinc nitrate tetrahydrate and hexamethylenetetramine. Prior to the heating process, the seeding solution was immersed in cold bath (0°C). XRD analysis had shown sharp peaks in diffractogram, indicating the high crystallinity of ZnO nanostructures. The crystallite size was determined using Scherrer equation and Williamson-Hall method. Other relevant parameters including stress, strain, and energy density were calculated using Williamson-Hall assuming UDM, UDSM, and UDEDM. The results had revealed that crystallite size calculated with Williamson-Hall method is more accurate than Scherrer equation.

Hydrogen is a promising alternative energy without greenhouse gas emissions. The transition metal carbides (TMCs) are considered a sustainable alternatives to noble metals in catalysis. Among the TMCs, Co[Formula: see text]C ([Formula: see text] = 2, 3) nanoparticles (NPs) act as an excellent electrocatalyst for hydrogen evolution reaction (HER) by water splitting. In our report, Co[Formula: see text]C nanocomposites were synthesized by wet chemistry method using cobalt (II) acetate, sodium hydroxide as precursors and triethylene glycol as solvent. In addition, Co2C NPs were synthesized by similar wet chemistry method using cobalt (II) acetate as precursors and triethylene glycol, oleylamine as solvent. The cobalt carbide NPs exhibited high electrocatalytic activity. Co[Formula: see text]C nanocomposites performed a −0.33 V onset potential and 91 mV/dec Tafel slope, while the Co2C NPs exhibited a better performance of −0.27 V and 60 mV/dec, respectively.

Acicular Mullite

Mullite was synthesized by firing precursors prepared from kaolinite via a wet chemistry method at various temperatures. The acicular mullite grains were formed in samples with addition of AlF3 by this process. The phase evolution and morphology of the fired samples were investigated. For the samples without AlF3, the mullitization began to occur at 1300 and almost completed at 1550 , the grains formed were normal-shaped. For the samples with AlF3, acicular mullite was formed, and mullitization began to occur at 1100 and completed at 1250 . The growth of the acicular mullite was associated with a liquid phase. The formed acicular mullite was alumina-rich and had a composition of about 73.4 wt% Al2O3 and 26.6 wt% SiO2 (Al2O3/SiO2=1.65, molar ratio).
