Abstract：
Climate neutrality for the year 2050 is the goal assumed at the level of the EU27+UK. As Romania is no exception, it has assumed the gradual mitigation of pollution generated by the energy sector, and by 2030, according to \'Fit for 55\', the share of energy from renewable sources must reach 42.5% from total energy consumption. For the rest of the energy produced from traditional sources, natural gas and/or coal, modern technologies will be used to retain the gaseous noxes. Even if they are not greenhouse gases, NO and SO2, generated from fossil fuel combustion, cause negative effects on the environment and biodiversity. The adsorption capacity of different materials, three nanomaterials developed in-house and three commercial adsorbents, both for NO and SO2, was tackled through gas chromatography, elemental analysis, and Fourier-transform infrared spectroscopy. Fe-BTC has proven to be an excellent material for separation efficiency and adsorption capacity under studied conditions, and is shown to be versatile both in the case of NO (80.00 cm3/g) and SO2 (63.07 cm3/g). All the developed nanomaterials generated superior results in comparison to the commercial adsorbents. The increase in pressure enhanced the performance of the absorption process, while temperature showed an opposite influence, by blocking the active centers on the surface.
摘要：
2050年的气候中立是欧盟27+英国的目标。罗马尼亚也不例外，它假设逐步减轻能源部门产生的污染，到2030年，根据“适合55岁”，可再生能源的份额必须达到总能耗的42.5%。对于传统来源产生的其余能量，天然气和/或煤炭，现代技术将被用来保留气态的氢气。即使它们不是温室气体，化石燃料燃烧产生的NO和SO2，对环境和生物多样性造成负面影响。不同材料的吸附能力，内部开发的三种纳米材料和三种商业吸附剂，NO和SO2都是通过气相色谱法解决的，元素分析,和傅里叶变换红外光谱。在研究条件下，Fe-BTC已被证明是分离效率和吸附能力的优异材料，并且在NO（80.00cm3/g）和SO2（63.07cm3/g）的情况下都具有通用性。与商业吸附剂相比，所有开发的纳米材料都产生了优异的结果。压力的增加增强了吸收过程的性能，虽然温度表现出相反的影响，通过阻挡表面上的活动中心。
