Zinc acetylacetonate hydrate

About 0.9 mmol of zinc (IE) acetylacetonate hydrate and appropriate quantities of vanadyl (IV) acetylacetonate are dissolved in a 250 mL 1 4 volume mixture of ethylene glycol and methyl alcohol. An ultrasonic bath is used to hasten the dissolution. The contents are stirred for 2 h to get a homogeneous solution. To this, a 5 wt% aqueous solution of polyvinyl alcohol (mol. wt. = 72,000) is added until a viscous gel is produced. The gel is first dried at 273 K for a day followed by calcination at 600°C for 1 h to obtain vanadium doped ZnO nanorods.
