Abstract The variability of CO 2 hydrogenation reaction demands new potential strategies to regulate the fine structure catalysts for optimizing pathways. Herein, we report a dual‐site strategy boost catalytic efficiency ‐to‐methanol conversion. A descriptor, τ , was initially established screening promising candidates with low‐temperature activation capability and sequentially high‐performance catalyst fabricated centred oxophilic Mo single atoms, who further decorated Pt nanoparticles. In hydrogenation, obtained possess remarkably‐improved methanol generation rate (0.27 mmol g cat. −1 h ). For comparison, singe‐site Pt‐based can only produce ethanol formate acid at relatively low (0.11 0.034 acid), respectively. Mechanism studies indicate that introduction species could create an active hydrogen‐rich environment, leading alterations adsorption configuration conversion pathways *OCH intermediates on sites. As result, selectivity successfully switched.

Abstract Laboratory‐prepared Gnp using molten salt, commercial and reduced graphene oxide (rGO) have been characterized utilized as support for CO 2 hydrogenation catalysts. Ni− Ru− catalysts supported over Gnp, rGO deeply at different stages Raman, IR, XRD, FE‐SEM‐EDXS, SEM‐EDXS, XPS, TEM, also addressing carbon loss before reaction evolved species, thus allowing a better comprehension of the produced materials. Ni Ru/rGO were inactive while Gnp‐supported ones active. Ru has found almost completely selective toward reverse Water Gas Shift to CO, approaching forecasted thermodynamic equilibrium 723 K, in tested conditions (Y ~55 %), with an apparent activation energy range 70–90 kJ/mol. Exhaust pointed out presence sulfur partially linked matrix producing corresponding metal sulfide detection surface oxidized species cationic form adsorbed well. The metal‐based nanoparticles displayed quite narrow size distribution, confirming promising behavior these catalytic systems utilization.
