Compared with industrial used Pt-and Cr-based catalyst in dehydrogenation (DH) of light alkanes, the sulfide V-K/γ-Al 2 O 3 catalyst reported in this study shows lower cost and toxicity, and significant DH performance. The yield to isobutene reached as high as 52.9%, which is among the highest reported to date. We attribute such high isobutene yield to the precise
