Figure 8. Effect of the Pd-PdO interfacial interaction and appropriate supports on the electrocatalytic performance of Pd-based oxides. (A) Diagram of NRR process on the Pd-PdO interface; (B) the relation between the varied irradiation times and the reduction degree (blue line) and NH₃ yield rate (brown line) of PdO/CNTs; (C) LSV curves of PdO/CNTs with different irradiation times; (A-C) reproduced with permission from^[150]: Copyright 2019, The Royal Society of Chemistry; (D) diagram of the introduction of ordered mesoporous carbon over Pd/OMC and Pd-PdO/OMC catalysts. The CV curves of Pd-PdO/OMC and its counterparts measured in different solutions: (E) 0.5 M H₂SO₄ solution; (F) 0.5 M H₂SO₄ + 0.5 M HCOOH solution; (D-F) reproduced with permission from^[151]: Copyright 2020, Elsevier.
