Abstract

Selective synthesis of the monoclinic Cd(OH)2 and hexagonal Cd(OH)2 was successfully achieved by controlling the reaction temperature and concentrations of Cd ion and NaCl in the solution. Monoclinic Cd(OH)2 was obtained when the amount of NaCl in the solution was 3∼5 mmol and hexagonal Cd(OH)2 was synthesized for NaCl amount either above 6 mmol or 2 mmol NaCl while other parameters were fixed as follows (reaction temperature: 30 °C,0.01 M Cd(NO3)2: 100 ml, 0.1 M NaOH: 100 ml).It is confirmed that the specific shape of the stratified CdS synthesized by sulphidizing Cd(OH)2 of different crystal structures affected the photocatalytic activity.
