“…1), palladium is more prone than the previously considered metals to forming extremely thin 2D nanosheets by means of top-down methods. According to earlier reports, successful deposition of a Pd monolayer onto Al (111), 61 Pt(111), 62 Ni(111), 63 Mo (100), 64,65 Ta (110), 66 Re{0001}, 67 and HOPG 68 can be achieved through a thermal evaporation approach. Among the most common methods for the synthesis of 2D Pd layers is CO-mediated growth, [69][70][71][72][73] electrochemical deposition, [74][75][76] and the reduction of a PdCl 2 -graphite intercalation compound precursor.…”
