Summary

Chemical engineering processes are typically governed by multiple unit operations. To minimize the energy consumption and economic cost, researchers face the challenge of integrating multiple steps of reactions and separations. A tandem reaction involves sequential reactions within one condition, presenting an effective scheme for emerging chemical industries (1). On page 1257 of this issue, Yan et al. (2) present a tandem catalyst with porous overcoating structures, In2O3-Pt/Al2O3, for coupling catalytic propane dehydrogenation with selective H2 combustion.
