CeZrO 2 can effectively catalyse the generation of dimethyl carbonate (DMC) by direct reaction of carbon dioxide (CO₂) and methanol (MeOH). However, its morphologically controllable synthesis and resolution of particle agglomeration remain a challenge. In this paper, uniformly dispersed rod-like structures were synthesised by adjusting the composition of the reaction solvent during CeZrO 2 synthesis. Experiments and characterisation showed that the addition of alcohol directly affected the morphology and aggregation of ions in solution and promoted the reduction of Ce 4+ to Ce 3+ , thus improving the catalytic performance of rod-shaped CeZrO 2 . When n-butanol was added at an alcohol-to-water ratio of 1/1, the generation of DMC has been optimised at 4.36 mmol/g, which was about 10% higher than the performance of DMC from a single aqueous solution. In this work, a simple, efficient and rapid modification method was used to achieve the improvement of catalyst performance, and the modulation of the reaction solvent can effectively reduce the cost of catalyst production compared with the doping modification of the catalyst with metal elements, and this study is an important reference for the optimisation of the performance of other types of catalysts.
