摘　　要：Ultrafast reaction kinetics is essential for rapid detection,synthesis,and process monitoring,but the intrinsic energy barrier as a basic material property is challenging to tailor.With the involvement of nanointerfacial chemistry,we propose a carbonization-based strategy for achieving ultrafast chemical reaction.In a case study,ultrafast Griess reaction within 1 min through the carbonization of N-(1-naphthalene)ethylenediamine(NETH)was realized.The carbonization-mediated ultrafast reaction is attributed to the synergic action of reduced electrostatic repulsion,enriched reactant concentration,and boosted NETH nucleophilicity.The enhanced reaction kinetics in o-phenylenediamine-Cu^(2)+and ophenylenediamine-ascorbic acid systems validate the universality of carbonization-engineered ultrafast chemical reaction strategy.The finding of this work offers a novel and simple tactic for the fabrication of multifunctional nanoparticles as ultrafast and effective nanoreactants and/or reporters in analytical,biological,and material aspects.
