Vanadium phosphorous oxide (VPO) catalysts have been recognized as heterogeneous catalyst for selective oxidation of low-carbon alkanes i.e., n -butane toward maleic anhydride. This process has widely gained attention globally due to its highly selective and cost-effective process. Herein, we employed Cd 0 . 2 Zn 0 . 8 S as a support for the VPO catalyst and evaluated its n -butane catalytic performance. Compared to the unpromoted catalyst (Blank-VPO), a higher n -butane conversion and MA yield were successfully obtained from the promoted catalyst (Cd 0 . 2 Zn 0 . 8 S@VPO). Interestingly, it reduces the byproducts, i.e., CO 2 and CO emission. Characterization methods such as TGA, XRD, EDS, SEM, FTIR, NH 3 -TPD, XPS, TEM, and Raman spectroscopy were used to characterize the Cd 0 . 2 Zn 0 . 8 S, VPO precursor and catalyst. Graphical Abstract
