The catalytic applications of micron Cu powder are limited due to its large particle size and small specific surface area. Modifying micro-Cu achieve a high performance is challenge in the application copper. In this work, was used synthesize CeO2–Cu catalyst, phase composition pore structure were analyzed using XRD, BET, etc. CO2 hydrogenation catalyst comparison with CeO2 Cu, we found that exhibited synergistic effect between cerium, resulting much higher at 500 °C than or alone. H2-TPR TEM characterization revealed formed interfacial interactions relatively Ce–Cu interface, where cerium oxide could promote reduction CuO lower temperature. Additionally, confinement for oxygen vacancy concentration, thereby promoting performance. Cu–CeO2 interaction provides valuable insights into powder.
