An Efficient Support-Free Nanoporous Co Catalyst for Reverse Water–Gas Shift Reaction
Abstract
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.
