Increasing the NO concentration up to 4.5% significantly enhanced HCN production, achieving a maximum carbon\u2010based yield of 3.5%. Elevating the temperature further improved activity, with the highest HCN yield of 4.8% obtained at 475\u00b0C. Comparison between ramping and constant\u2010temperature conditions demonstrated that the initial reaction temperature strongly influenced product distribution, with ramping from 300\u00b0C enabling substantially higher CH\n                    <jats:sub>4<\/jats:sub>\n                    conversion and HCN formation. In situ Fourier Transform Infrared (FTIR) spectroscopy identified Pt\u2010CO, Pt\u2010CN, Pt\u2010NCO, and Al\u2010NCO species, among which Pt\u2010CO showed the strongest correlation with HCN production, whereas strongly adsorbed Pt\u2010CN behaved predominantly as an inhibiting spectator species. Temperature\u2010swing operation effectively promoted desorption of such inhibiting species, thereby enhancing HCN and NH\n                    <jats:sub>3<\/jats:sub>\n                    yield, a trend supported by in situ dispersive x\u2010ray absorption fine structure (DXAFS) analysis. These findings highlight the critical role of dynamically controlling surface intermediates in improving low\u2010temperature HCN synthesis.\n
