Abstract The electrocatalytic hydrogen evolution reaction (HER) is a promising route to produce sustainable energy carrier for global carbon neutrality. HER performance largely determined by the overall proton activities, but identification of such key activities in microscopic process rather difficult. Herein, study demonstrates visualized concept integrating fundamental with electrochromic technology on well‐designed Pt@WO 3 platform acidic electrolyte, where can be rapidly discriminated color changes electrode. In contrast bare WO counterpart, electrode displays more positive potential initial‐coloration state and faster decoloration rate associated significantly improved kinetics intercalation deintercalation within component. Correspondingly, as‐prepared catalyst exhibits remarkable activity lower onset‐potential (45 mV, adsorption accumulation) smaller Tafel slope (50 mV dec −1 , desorption), nearly 11.1‐ 3.5‐fold enhancement than those counterpart. It believed that work interesting visualization functionality into may improve readability advance exploration intelligent electrocatalysts.
