Abstract Developing solid‐solution nano‐alloys from immiscible metals has garnered significant interest; however, the high formation entropy poses substantial challenges in synthesis, hindering a comprehensive understanding of catalytic mechanisms under alloying effects. Herein, synthesis small‐sized (≈2.5 nm) Ru x Ni 1‐x alloy nanoparticles with precisely controlled Ru/Ni ratios across broad compositional range is reported for first time, despite their bulk immiscibility. The 0.76 0.24 /TiO 2 catalyst, an optimized ratio, delivers superior photo‐thermal activity CO methanation, achieving CH 4 production rate 3.58 mol g metal −1 h 94% selectivity at 250 °C light irradiation, representing 2.82‐fold enhancement over monometallic Ru/TiO . Comprehensive investigations reveal that reconstruction electronic structure Ru–Ni active sites enhances adsorption/activation reactants, promotes transformation intermediate HCO 3 * to HCOO , and facilitates separation photo‐generated charge carriers witnessed by femtosecond time‐resolved transient absorption (fs‐TA) spectroscopy. These combined effects collectively result significantly enhanced performance. This work highlights potential regulating combinations conversion, underscoring promise these cost‐effective alloys heterogeneous catalysis.
