A Co-based catalyst is a great candidate for the hydrogenation of CO2. Herein, a support-free nanoporous Co catalyst with high surface area and hierarchical pores was prepared by chemical dealloying, which exhibited excellent performance in the reverse water–gas shift (RWGS) reaction. High conversion of 54.2% and RWGS reaction rate of 812 μmolCO2/gcat/s could be obtained at a high weight hourly space velocity.
