Spinel-structure catalyst catalyzing CO₂ hydrogenation to full spectrum alkenes with an ultra-high yield

Spinel-like ZnFe₂O₄ is tailor-made synthesized for catalyzing CO₂ hydrogenation, achieving an ultra-high yield (1858.1 g kg_cat^-1 h^-1) of full spectrum alkenes in a three-stage reactor system. This study provides rational design concepts from catalyst to equipment amelioration by combining promoter regulation and ex situ water removal, efficiently catalyzing CO₂ into valuable chemical feedstocks with industrial potential.
