Data set for "Surfactant Effects on the Synthesis of Porous Cerium Oxide from a Type IV Deep Eutectic Solvent"

This dataset relates to a novel, low temperature and green method for atom-efficient solvothermal synthesis of crystalline, micelle templated cerium IV oxide (ceria) from a type IV deep eutectic solvent (DES) comprising a hydrated cerium containing metal salt, cerium(iii) nitrate hexahydrate (Ce(NO₃)₃·6H₂O), and a hydrogen bond donor, urea, in a molar ratio of 1:3.5. We have used high concentration (20% w/w) solutions of C-12 and C-16 alkyl chain length cationic surfactants (CₙTAB and CₙTANO₃) and C-16 alkyl chain length non-ionic surfactant BrijC₁₀ in the DES to alter the porosity of the cerium oxide produced. The characterisation of the cerium oxide has been carried out using scanning and transmission electron microscopy (SEM/TEM), N₂ sorption, Small Angle X-ray Scattering (SAXS) and temperature programmed reduction (TPR) to understand and quantify the nature of the crystallinity, morphology and porosity along with CO oxidation for the catalytic activity of the material.

Included in the dataset are the X-ray diffraction (XRD), SAXS, N₂ sorption, SEM Energy Dispersive X-Ray Analysis (EDX), X-ray photoelectron (XPS) and CO oxidation characterization data for these materials.

本数据集涉及一种新颖、低温且绿色的原子经济性溶剂热合成方法，可通过由含铈水合金属盐——硝酸铈(III)六水合物（cerium(iii) nitrate hexahydrate, Ce(NO₃)₃·6H₂O）与氢键供体尿素按1:3.5摩尔比组成的IV型低共熔溶剂（deep eutectic solvent, DES），制备得到胶束模板化的结晶型二氧化铈（cerium IV oxide, ceria）。本研究采用C12、C16烷基链长阳离子表面活性剂（CₙTAB、CₙTANO₃）以及C16烷基链长非离子表面活性剂BrijC₁₀的高浓度（20% 质量分数，w/w）低共熔溶剂溶液，以此调控所制备氧化铈的孔隙结构。针对所制得的氧化铈材料，本研究借助扫描电子显微镜与透射电子显微镜（scanning and transmission electron microscopy, SEM/TEM）、氮气吸脱附测试、小角度X射线散射（Small Angle X-ray Scattering, SAXS）以及程序升温还原（temperature programmed reduction, TPR）开展表征工作，以解析并量化其结晶度、形貌与孔隙特性，并通过CO氧化反应评估该材料的催化活性。
