Dinuclear metal synergistic catalysis （DMSC） has been proved powerful in boosting CO2reduction,while this has not been achieved in heterogeneous catalysts with long-range order *** this study,we,by introduction of metal catalytic centers into an indium-based metal-organic framework （MOF）,obtained a series of isostructural In-MOFs,including three MOFs with mononuclear metal catalytic center （M-In）,three MOFs with dinuclear homometallic catalytic centers （MM-In）,and three MOFs with dinuclear heterometallic catalytic centers (MM’-In,M/M’=Co（II）,Ni（II）,Zn（II）).It was found that all these MOFs can serve as catalysts for photochemical CO2reduction to *** with M-In,the catalytic activities of MM-In were obviously enhanced,and that of MM’-In was further significantly *** example,the CO yield of Co Zn-In reaches a record value of 12,700μmol g-1h-1,which is 4.0,8.1,9.4,and 18.6-fold higher than that of Co Co-In,Zn Zn-In,Co-In,and Zn-In,***,the catalytic activities of Co Ni-In and Ni Zn-In also show different fold increase than those of corresponding dinuclear homometallic and mononuclear metallic *** results of control experiments and theoretical calculation reveal that the higher catalytic activities of MM-In over M-In can be ascribed to the DMSC effect,and the higher catalytic activity of MM’-In over MM-In can be ascribed to the strengthened DMSC *** work reveals the relationship between DMSC effect and bimetal centers in CO2reduction,which provides new insights into the DMSC and paves a new way to design highly active catalysts for photochemical CO2reduction.

Carbon dots self-assembly enables near-infrared emission

Science China Chemistry 2025年

作者： Shurong Ding Shasha liu Yuzhuo Yang linlin shi Yongqiang Zhang Jingkun Yu Haoqiang Song Yingge shi Siyu Lu College of Chemistry Pingyuan Laboratory Zhengzhou University Henan Institute of Advanced Technology Zhengzhou University

In the fields of biomedicine, detection, and anti-counterfeiting, there is a widespread demand for cost-effective, easily synthesized, and environmentally friendly near-infrared(NIR) materials. Carbon dots(CDs), a cheap and non-toxic zero-dimensional carbon nanomaterial exhibiting exceptional photoluminescence(PL) properties and facile structural modification, have emerged as a promising candidate for the development of novel NIR materials. This study presents the synthesis of CDs capable of emitting a wide range of wavelengths from blue to NIR(456–836 nm) as their concentrations increase. The incorporation of oxygen and nitrogen co-doped atoms facilitates the optimization of non-coplanar angles, thereby promoting favorable π-πstacking interactions. This leads to the formation of metal-free rigid clusters through interconnecting adjacent nanoparticles in a gear-like meshing pattern through self-assembly. Consequently, intramolecular motion is constrained, vibration coupling is mitigated, non-radiative transition losses are minimized, and efficient NIR emission from CD clusters in high concentrations is ensured. Furthermore, NIR light-emitting diode(NIR LED) based on the CD clusters was successfully fabricated and employed for various applications including information encryption, anti-counterfeiting, and penetration detection in the field of NIR imaging.

在丁基橡胶(IIR)阻尼材料中添加受阻酚小分子AO-80和环氧树脂618,得到IIR/AO-80二元复合材料和IIR/AO-80/618三元复合阻尼材料。采用动态热机械分析(DMA)及稳定性贮存实验对其阻尼性能和稳定性进行了研究。结果表明,IIR/AO-80二元复合材料阻尼性能有所提高,且tanδ随AO-80用量的增加而呈现先增大后减小的趋势,但其贮存稳定性差;在加入618作共溶剂后,所得IIR/AO-80/618三元复合阻尼材料阻尼性能显著提高,tanδ随618用量的增加而先增大后减小,且618的加入可以改善体系的相容稳定性。
