In the case of CO2 thermal‐catalytic hydrogenation, highly selective olefin generation and subsequent olefin secondary reactions to fuel hydrocarbons in an ultra‐short residence time is a huge challenge, especially under industrially feasible conditions. Here, we report a pioneering synthetic process that achieves selective production of high‐volume commercial gasoline with the assistance of fast response mechanism. In situ experiments and DFT calculations demonstrate that the designed NaFeGaZr presents exceptional carbiding prowess, and swiftly forms carbides even at extremely brief gas residence times, facilitating olefin production. The created successive hollow zeolite HZSM‐5 further reinforces aromatization of olefin diffused from NaFeGaZr via optimized mass transfer in the hollow channel of zeolite. Benefiting from its rapid response mechanism within the multifunctional catalytic system, this catalyst effectively prevents the excessive hydrogenation of intermediates and controls the swift conversion of intermediates into aromatics, even in high‐throughput settings. This enables a rapid one‐step synthesis of high‐quality gasoline‐range hydrocarbons without any post‐treatment, with high commercial product compatibility and space‐time yield up to 0.9 kggasoline·kgcat‐1·h‐1. These findings from the current work can provide a shed for the preparation of efficient catalysts and in‐depth understanding of C1 catalysis in industrial level.
