“…[8] However, the yield of DMC over CeO 2 , metaldoped CeO 2 or supported CeO 2 catalysts (especially in dehydrant-free reactions) has been unsatisfactory (0.1-5.0 %) (Table S3). Additionally, the catalysts suffer deactivation and complex production protocols, as demonstrated with Ce/SBA-15, [9] H-CeO 2 -1.2, [10] Ce-UiO-66-2, [11] CeO 2 /Al 2 O 3 [12] and Ce 1 Zn 0.1 O δ . [13] Meanwhile, the unique properties of ionic liquids (ILs) can engender dramatic synergy with nanoparticles to enhance the attributes of nanocatalyst@IL composites for catalytic applications.…”

As a crucial strategy towards a sustainable chemical industry, the direct synthesis of dimethyl carbonate (DMC) from renewable carbon dioxide (CO2) and methanol (MeOH) is studied, using CeO2 nanoparticles modified with 1‐butyl‐3‐methylimidazolium hydrogen carbonate ([BMIm][HCO3]) devoid of stoichiometric dehydrating agents. The synthesized CeO2@[BMIm][HCO3] catalyst having high thermal stability harnesses the unique physicochemical properties of CeO2 and the ionic liquid to exhibit a DMC yield of 10.4% and a methanol conversion of 16.1 % at optimal conditions (pressure of CO2 = 5 MPa; temperature = 130 °C). The catalytic behavior of CeO2@[BMIm][HCO3] studied with a detailed XRD, XPS, CO2 and NH3‐TPD, Raman spectroscopy, TGA, FTIR, SEM and TEM suggests that the synergy between the two catalytic components originating from an increased surface oxygen vacancies boosts the overall catalytic performance. After several recycling tests, the catalyst demonstrated no significant reduction in DMC yield and methanol conversion. This platform is an attractive approach to synthesize thermally stable nanoparticle@ionic liquid that retains and merges the physical attributes of both materials for producing useful bulk chemicals from readily available chemical resources.
