Experimental Characterization Dataset of UV-Modified and APTES-Functionalized Graphene Oxide Foam for Enhanced CO₂ Adsorption

This dataset supports the research hypothesis that ultraviolet (UV) irradiation and subsequent amine functionalization can enhance the surface properties and CO₂ adsorption performance of graphene oxide foam (GOF) adsorbents. The hypothesis is based on the premise that UV treatment can modify the GOF structure by introducing additional oxygen-containing functional groups, creating structural defects, and improving accessibility to adsorption sites, while APTES functionalization can further enhance CO₂ affinity through amine–CO₂ interactions. The dataset contains experimental results including CO₂ adsorption measurements, Fourier-transform infrared spectroscopy (FTIR) spectra, X-ray diffraction (XRD) patterns, and Brunauer–Emmett–Teller (BET) surface analysis data. The CO₂ adsorption data demonstrates the adsorption performance of pristine GOF, UV-treated GOF, and APTES-functionalized GOF samples. FTIR data can be used to evaluate changes in surface functional groups associated with UV modification and amine grafting. XRD data provides information regarding structural changes and variations in interlayer spacing of the GOF framework, while BET analysis describes the textural properties, including surface area, pore volume, and pore size distribution. The data indicates that UV treatment and amine functionalization contribute to improved CO₂ adsorption performance compared with pristine GOF. The combined characterization results provide insights into the relationship between surface chemistry, structural modification, porosity, and adsorption behavior. The dataset can be interpreted to evaluate the influence of material modification strategies on GOF-based adsorbents and can be used as supporting information for the development of advanced carbon-based materials for CO₂ capture applications.本数据集支持如下研究假说：紫外（UV）辐照与后续胺基功能化可有效提升氧化石墨烯泡沫（GOF）吸附剂的表面性能与CO₂吸附性能。该假说的核心前提为：紫外处理可通过引入额外含氧官能团、构建结构缺陷以及优化吸附位点可及性来修饰GOF微观结构；而APTES功能化则可借助胺基与CO₂的特异性相互作用，进一步增强材料对CO₂的亲和能力。 本数据集涵盖多组实验表征结果，具体包括CO₂吸附性能测试数据、傅里叶变换红外光谱（FTIR）谱图、X射线衍射（XRD）图谱以及布鲁诺尔-埃米特-特勒（BET）表面分析数据。其中，CO₂吸附数据完整呈现了原始GOF、UV处理GOF以及APTES功能化GOF三类样品的吸附表现。FTIR谱图可用于定量与定性评估紫外改性与胺基接枝过程中，材料表面官能团的演变规律。XRD图谱则可提供GOF骨架的结构变化与层间距波动相关的关键信息；而BET表面分析则可系统表征材料的织构特性，涵盖比表面积、孔体积与孔径分布等核心参数。 实验结果表明，相较于原始GOF样品，经UV辐照与胺基功能化联合处理的GOF吸附剂的CO₂吸附性能得到显著提升。综合各项表征结果可深入揭示材料表面化学特性、结构改性手段、孔隙结构与吸附行为之间的内在关联机制。本数据集既可用于评估各类改性策略对GOF基吸附剂的调控效果，亦可作为开发面向CO₂捕集应用的先进碳基吸附材料的支撑性研究资料。
