2D platinum diselenide (PtSe2) exhibits exceptional layer‐dependent electrical properties and high catalytic activity for hydrogen evolution reactions, making it an ideal system for studying structure–activity correlations. However, the synthesis of high‐quality atomically thin PtSe2 materials has proven challenging. This study presents a simple chemical vapor deposition method for synthesizing high‐quality ultrathin 1T‐PtSe2 ribbons on Au foils, making it easily applicable. Theoretical and experimental results confirm that these atomically thin 1T‐PtSe2 ribbons possess abundant catalytic sites and can serve as ideal electrocatalysts. This study advances the large‐scale synthesis and potential application of ultrathin transition metal disulfides and presents a novel method for designing and synthesizing highly active ultrathin catalysts. A controllable synthesis method for high‐quality atomically thin PtSe2 is crucial for both fundamental research and practical applications. In this study, large‐scale ultrathin 1T‐PtSe2 ribbons of high quality are synthesized on Au foils and utilized as electrocatalysts. The results provide clear insight into the morphology and structure of PtSe2 ribbons and offer a new avenue for the rational design and modulation of high‐performance 2D catalysts for hydrogen evlution reaction.
