a Operando Pd K-edge XANES of Pd1 ASAC catalyst measured under the Suzuki coupling reaction conditions. b Corresponding Bader charge of Suzuki cross-coupling reaction over the Pd1 ASAC. c Yield of biphenyl after two-hour reaction for Pd single atoms loaded on different supports at 298 K. d DFT Model and high-resolution TEM images of Pd1-CeO2(111), Pd1-CeO2(110) ASAC, Pd1-CeO2(100). e Activity of Suzuki cross-coupling catalyzed by Pd single atoms supported on facet-dependent CeO2. Conditions: 1 (0.5 mmol), 2 (ArB(OH)2, 0.6 mmol), Pd1-CeO2(110) ASAC (5 mg, 0.35 mol%), K2CO3 (1.5 mmol), H2O/EtOH (2 mL:2 mL), 25 °C, 2 h.
