a Scheme of in-situ regioselective reconstruction of Ni-Ce(OH)3/CeO2 to form the dual-active sites of the creatively carburized Ni clusters and precisely designed FLPs. b XRD patterns of the Ni-Ce(OH)3/CeO2 pre-catalysts and spent Ni-Ce(OH)3/CeO2 catalysts. c High-resolution TEM images of the Ni-Ce(OH)3/CeO2 pre-catalysts. d CO yields of the RWGS reaction. e Comparison of CO generation rates of Ni-Ce(OH)3/CeO2 (this work) and other state-of-the-art Ni catalysts through RWGS reaction under similar reaction conditions (see Supplementary Table 1 for more details). f Catalytic stability of Ni-Ce(OH)3/CeO2. Reaction conditions: Ni-Ce(OH)3/CeO2 (50 mg), WHSV (72,000 mL gcat−1 h−1), H2:CO2:N2 of 3:1:8 and 550 °C. All catalysts were subjected to in-situ treatment at 600 °C for 2 h under reaction conditions prior to performance evaluation. The spent Ni-Ce(OH)3/CeO2 catalysts referred to the Ni-Ce(OH)3/CeO2 pre-catalysts that had undergone the 1000 h stability test.
