Synthesis, Characterizations of Molybdenum disulfide& Zinc oxide for Photo catalysis & bio sensing application is reported in this work. The material was synthesized using two step hydrothermal route from Sodium Molybdate, Sulfur, Hydrazine, Ammonia & Zinc Nitrate hexa-hydrate. In first step molybdenum disulfide is synthesized. The reaction temperature was 150oC. The time of reaction was 34 hrs. The resultant was then washed & dried to obtain MoS2 in form of shimmery black powder, In second step MoS2.ZnO is synthesized the reaction temperature was 80oC. The time of reaction was 6 hrs.
X-Ray studies confirmed the formation of crystalline MoS2.ZnO. The SEM of sample confirms the flower-like morphology of the sample. The TEM image reveals that sample is consist in of spherical particles, Nano flowers and rod like structures. The EDX results are also in good agreement with the stoichiometric values of the chemicals used. Finally study regarding the Bio sensing and photo catalytic applications has been conducted to check out the sensitivity and catalytic activity of molybdenum disulfide/Zinc Oxide Nano composite. For this purpose experiments for non-enzymatic detection of glucose has been performed through 3-electrode based system. First, CV curves for the different concentration of glucose in pH 7.0 PB solution are recorded and analyzed without using any enzyme. Results have shown a good relation between peak current and concentration of glucose in range of 50 μm and 5000 μm. So, effective sensitivity, large surface area and high electrical conductivity made Nanostructure of MoS2/ZnO a promising material for bio sensing. in second phase MoS2/ZnO electrode has been tested for degradation of organic dyes like MB, RHB , Sandoz Yellow etc. due to good optical properties of ZnO and band gap tuning using MoS2 the large range of light is harvested which increase the degradation rate of organic dyes as shown in degradation graphs.
