چکیده:

Recently, synthesis of tungstate nano materials have been extensively investigated [1-3]. For example, metal tungstate nanorods/nanowires have been synthesized via a facile hydrothermal process [4]. Yu et al. synthesized thin 1D and 2D CdWO4 nanocrystallites by polymer controlled crystallization [5]. Wang et al. have synthesized CdWO4 nanorods or nanofibers by hydrothermal treatment using cetyltrimethylammonium bromide (CTAB) as capping molecule [6]. To the best of our knowledge, preparation of nanosized CoWO4, NiWO4 and doped Ni1-xCoxWO4 compounds via hydrothermal has not been reported. In this paper, we report the hydrothermal preparation of Ni1-xCoxWO4 samples (where x = 0, 0.1, 0.25, 0.5 and 1.0) in the presence of cetyltrimethylammonium bromide (CTAB) as organic template and demonstrated the effect of reaction condition on the shape of the prepared materials
