%X Al<sub>2</sub>S<sub>3</sub>/MoS<sub>2</sub> nanocomposite has been synthesized through electrochemical method</span><span style=\"font-family:&quot;\"> and characterized by UV-Visible spectroscopy, XRD, SEM and <span>EDAX data. UV-Visible spectroscopy measurements
reveal that the Al<sub>2</sub>S<sub>3</sub>/MoS<sub>2</sub></span> nanocomposite has maximum absorption at 353.04 nm and this peak position
reflects the band gap of particles and it is found to be 2.51 eV which was
calculated using Tauc plot. X-Ray diffraction (XRD) reveals crystaline size to
be 49.85 nm which was calculated using Williamson-Hall (W-H) plot method. Photocatalytic
degradation of acetic acid, chloroacetic acid and trichloroacetic acid has been
studied by volumetric method using NaOH solution. Photocatalytic degradation of
chloroacetic acid and acetic acid follows first order kinetics. The
photodegradation efficiency for Al<sub>2</sub>S<sub>3</sub>/MoS<sub>2</sub> nanocomposite was found to be ¡Ö97.8%. A Taft linear free energy relationship is
noted for the <span>catalysed reaction with <i>¦Ñ</i>* = 0.233 and indicating electron
withdrawing groups</span> enhance the rate. An isokinetic relation is observed
with <i>¦Â</i> = 358 K indicating <span>that enthalpy factor controls the reaction rate.
The result of this paper suggests</span> the possibility of degradation of
organic compounds, industrial effluants and toxic organic compounds by
photodegradation process by ecofriendly Al<sub>2</sub>S<sub>3</sub>/ MoS<sub>2</sub>.
The antibacterial activity of Al<sub>2</sub>S<sub>3</sub>/MoS<sub>2</sub> nanocomposite was investigated. These particles were shown to have an effective
bactericide.
