Chemical fixation of CO₂ into fine chemicals is one of the key areas of research today to mitigate greenhouse gas CO₂ and its successful utilization as C1 building block. Nanocrystalline MgO has been synthesized by simple precipitation method followed by calcination at 450 °C. The materials are characterized thoroughly by several instrumental tools, which suggested the presence of mesoscopic void space and excellent catalytic activity for the synthesis of organic cyclic carbonates by chemical fixation of CO₂ on a wide range of epoxides at atmospheric pressure and room temperature within a short reaction time. Maximum product yields upto 99% for the cyclic carbonates are observed. It also displayed a high catalytic activity in the N-formylation of various amines by using formic acid as reagent (acts both as carbon source and reducing agent) at room temperature with excellent product yields upto 99.5%. This nanocrystalline MgO material showed high recycling efficiency for the cycloaddition of CO₂ onto the epoxides and no sign of catalyst deactivation.

将CO ₂化学固定为精细化学品是当今减轻温室气体CO ₂及其成功用作C1构件的主要研究领域之一。通过简单的沉淀方法，然后在450°C下煅烧，合成了纳米晶体MgO。该材料通过多种仪器工具进行了全面表征，这表明存在介观孔隙空间，并且具有通过化学固定CO ₂合成有机环状碳酸酯的出色催化活性。在大气压和室温下在很短的反应时间内就可以在多种环氧化物上使用。观察到环状碳酸酯的最大产物收率高达99％。通过在室温下使用甲酸作为试剂（兼作碳源和还原剂），在各种胺的N-甲酰化反应中也表现出很高的催化活性，优良的产物收率高达99.5％。这种纳米晶体MgO材料显示出高的循环效率，可将CO ₂环加成到环氧化物上，并且没有催化剂失活的迹象。
