Although platinum catalysts on nitrogen\u2010doped carbon (NC) show promising MOR activity, the coupled variation between Pt and NC during synthesis obscures their individual contributions. Herein, a solid\u2010phase interface reaction (SIR) successfully decouples their interactions, clarifying the role of each component. We define the ripple effect as the long\u2010range electronic modulation induced by Pt\u2013N coordination, which modulates the electronic state of Pt active sites in a long\u2010range manner and thus significantly accelerates MOR reaction kinetics. Based on this, a metal\u2010free catalytic promoter was developed. When combined with commercial 5\u2009wt% Pt\/C, the resulting Pt\/C@NC\u20106hr composite exhibits 1.67 times and twice the mass activity of 5 and 20\u2009wt% Pt\/C. Furthermore, statistical results indicate that the mass activity derived solely from the Pt on NC is 4.74 times higher than that of the original 5\u2009wt% Pt\/C catalyst, demonstrating a remarkably substantial activity enhancement. After 3600\u2009s chronoamperometry at 0.75\u2009V (vs. RHE), it maintains superior current density. This work elucidates the mechanism of microenvironment\u2010enhanced Pt catalysis via the ripple effect and offers a practical strategy for improving commercial Pt\/C.<\/jats:p>","DOI":"10.1002\/cssc.70598","type":"journal-article","created":{"date-parts":[[2026,3,29]],"date-time":"2026-03-29T17:58:57Z","timestamp":1774807137000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Boosting Methanol Electrooxidation on Pt\/C with a Metal\u2010Free Nitrogen\u2010Doped Carbon Cocatalyst via the Ripple Effect"],"prefix":"10.1002","volume":"19","author":[{"given":"Jiawen","family":"Li","sequence":"first","affiliation":[{"name":"State Key Laboratory of Advanced Materials for Intelligent Sensing Key Laboratory of Organic Integrated Circuit Ministry of Education &amp;
