Abstract

A MoS2/AlOOH composite was synthesized by calcining the reaction product of Na2MoO4, Na2S, HCl and basic Al2O3. The obtained composite was characterized using thermal analysis, X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, high-resolution transmission electron microscopy, ultraviolet–visible spectroscopy and infrared spectroscopy. The degradation reaction of methyl orange was used to evaluate the photocatalytic properties of the composite. The results showed that alumina existed in the form of AlOOH with the deposited nano-MoS2 on the surface. The composite contained an intensive absorption between 380 and 450 nm and presented excellent photocatalytic properties. In addition, the composite still retained a high catalytic activity after repeatedly used for three times. The catalytic activity of the composite was influenced by the initial concentration of methyl orange, the amount of the catalyst, the pH value, and the temperature. The composite was a promising photocatalyst for the removal of organic chemicals from wastewater.
