Regulated reaction pathway of CO2 photoreduction into CH4 by metal atom pair sites

Rare Metals 2024年第9期43卷 4620-4627页

作者： Dong-Po He Guang-Bing Huang jun Hu Yang Wu Xiao-Dong Li Qing-Xia Chen shan Zhu Wen-Sheng Yan jun-Fa Zhu Yang Pan Xing-Chen Jiao Key Laboratory of Synthetic and Biological Colloids Ministry of EducationSchool of Chemical and Material EngineeringJiangnan University Hefei National Research Center for Physical Sciences at Microscale National Synchrotron Radiation LaboratoryUniversity of Science and Technology of China Max Planck Institute of Microstructure Physics State Grid Anhui Electric Power Research Institute

The carbon dioxide （CO2） reduction process involves complex protonation, making the resulting product often unpredictable. To achieve the desired product, it is crucial to manipulate the reaction steps. Herein, we build the metal atom pair sites for selective CO2photoreduction into methane. As a prototype, Ni atom pair sites loaded on the Mo S2nanosheets were synthesized and verified by highresolution transmission electron microscopy （HRTEM）,X-ray photoelectron spectroscopy （XPS） and X-rayabsorption near edge structure spectra （XANES）. In-situ Fourier transform infrared spectroscopy （FTIR） monitors the*CHO group, a crucial intermediate in CH4production,during CO2photoreduction on the Ni-Mo S2nanosheets,whereas this monitoring is not observed for the Mo S2nanosheets. Also, theoretical calculations disclose that over the Ni-Mo S2nanosheet slab, the formation energy of*CHO intermediates is determined to be lower （0.585 e V） than the desorption energy of*CO intermediates for CO production（0.64 e V）, implying the higher selectivity of CH4production. Accordingly, the Ni-Mo S2nanosheets demonstrate a methane formation rate of 27.21μmol·g-1·h-1, coupled with an impressive electron selectivity of 94.2%.

Objective: Huazhi Rougan granules(HRGs) are a promising drug to improve alcoholic liver disease(ALD), but its mechanism remains unclear. Materials and Methods: Network pharmacology, molecular docking, and animal experiments were used to reveal the potential mechanism of HRG against ALD. Results: A total of 245 potential targets of HRG against ALD were obtained. Functional enrichment analysis suggests that HRG could synergistically regulate various biological pathways to exert therapeutic effects on ALD. Molecular docking showed that the key targets exhibited the good binding ability with the key compounds. The in vivo experiments showed that HRG can effectively alleviate pathological changes in liver tissue, improve blood lipid levels, antioxidant stress ability, and liver function, and reduce the release of inflammatory cytokines in the liver. Conclusions: This study reflects that HRG is an effective strategy for treating ALD, providing a basis for revealing the prevention and treatment mechanisms of ALD.

针对湖库周边农田淹没后土壤磷释放风险控制的问题,采用共热解法制备Ca改性生物炭(Ca-BC),通过X射线光电子能谱分析(XPS)、X射线多晶粉末衍射分析(XRD)、吸附实验和模拟培养实验等,进行Ca-BC对土壤磷赋存形态影响和稳定化机制研究.结果表明,Ca-BC吸附磷的过程符合Langmuir(R^(2)=0.940)和一级吸附动力学模型(R^(2)=0.961),表明该吸附过程为化学作用主导的单层吸附,最大吸附量达到267.93 mg·g^(-1).模拟培养实验表明,当Ca-BC添加量为1%时,土壤中较活跃性的交换态磷形态从7.42%下降至4.59%.XRD结果表明,Ca-BC吸附磷后出现Ca_(3)(PO_(4))_(2)和Ca_(5)(PO_(4))_(3)(OH)吸收峰,证明磷酸盐在生物炭表面形成较稳定的晶体沉淀.XPS分析表明,生物炭表面羰基官能团参与磷固定过程,提高了生物炭对磷的吸附能力.总体来讲,CaBC添加量大于1%时,对磷的释放有较好的固定能力,具备对土壤磷释放控制的潜在应用价值.
