Taking advantages of selective adsorption of surfacatnts or forein chemical species, the morphology-controlled synthesis of various shapes of photocatalytic materials was done to obtain the highest photoactivity. As the results, by using cetyltrimethylammonium bromide (CTAB) which acts as surfactant, dispersed CdS single crystals were obtained via a hydrothermal condition. Strong interaction between the cationic head groups of CTAB and the {001} planes of CdS hexagonal crystals result in a single-crystalline growth along [100] direction. On the other hand, uniform and single-crystalline α-Fe2O3 polyhedral nanoparticles in hexagonal crystal system named truncated hexagonal bipyramid (THB) were fabricated. Under hydrothermal condition, carboxymethyl cellulose (CMC) and hydrazine molecules play roles such as dispersant and capping agents, respectively, during the crystallographical growth. The optical and magnetic properties of the hematite particles were investigated as well.
