The high\u2010index facets (HIF) Pt nanocrystals are regarded as excellent catalytic activity and stability catalysts. However, nucleation, growth and evolution of high\u2010index facets Pt nanocrystals induced by defective sites is still a challenge. In this work, tetrahexahedron (THH) and hexactahedron (HOH) Pt nanocrystals are synthesized, which are loaded on the nitrogen\u2010doped reduced graphene oxide (N\u2010rGO) support of the integrated electrodes by the square wave pulse method. Experimental investigations and density functional theory (DFT) calculations are conducted to analyze the growth and evolution mechanism of HIF Pt nanocrystals on the graphene\u2010derived carbon supports. It shows that the H adsorption on the N\u2010rGO\/CFP support can induce evolution of Pt nanocrystals. Moreover, the N\u2010defective sites on the surface of N\u2010rGO can lead to a slower growth of Pt nanocrystals than that on the surface of reduced graphene oxide (rGO). Pt\/N\u2010rGO\/CFP (20\u00a0min) shows the highest specific activity in methanol oxidation, which is 1.5 times higher than that of commercial Pt\/C. This research paves the way on the design and synthesis of HIF Pt nanocrystal using graphene\u2010derived carbon materials as substrates in the future.<\/jats:p>","DOI":"10.1002\/smll.202309457","type":"journal-article","created":{"date-parts":[[2023,12,27]],"date-time":"2023-12-27T15:50:51Z","timestamp":1703692251000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["Evolution
