摘要: Molybdenum disulphide has been prepared by atmospheric-pressure hydrogen reduction of molybdenum trisulphide in the temperature range 400–750 °C for 4 h and characterized. Chemical analysis product confirmed S to Mo ratio 2.00 as desired MoS2, consistent with its thermogravimetric data an air atmosphere. MoS2 under these reducing conditions possessed a hexagonal structure n-type diamagnetic semiconducting behaviour lower surface area. The catalytic activity was studied liquid-phase hydrogenation nitrobenzene. X-ray studies on MoS3 when reduced at 750 48 indicated that so formed is unstable, resulting formation over-reduced products Mo2S3 Mo.
