| 1 | In-situ constructing Cu_(1)Bi_(1)bimetallic catalyst to promote the electroreduction of CO_(2)to formate by synergistic electronic and geometric effects显示文摘Electrochemical CO_(2)reduction to formate is a potential approach to achieving global carbon neutrality.Here,Cu1Bi1bimetallic catalyst was prepared by a co-precipitation method.It has a ginger like composite structure(CuO/CuBi_(2)O_(4))and exhibited a high formate faradaic efficiency of 98.07%at–0.98 V and a large current density of–56.12 mA.cm^(-2)at–1.28 V,which is twice as high as Bi2O3catalyst.Especially,high selectivity(FE^(–)_(HCOO)>85%)is maintained over a wide potential window of 500 mV.In-situ Raman measurements and structure characterization revealed that the reduced Cu1Bi1bimetallic catalyst possesses abundant Cu-Bi interfaces and residual Bi-O structures.The abundant Cu-Bi interface structures on the catalyst surface can provide abundant active sites for CO_(2)RR,while the Bi-O structures may stabilize the CO_(2)^(*–)intermediate.The synergistic effect of abundant Cu-Bi interfaces and Bi-O species promotes the efficient synthesis of formate by following the OCHO^(*)pathway. | Houan Ren Xiaoyu Wang Xiaomei Zhou Teng Wang Yuping Liu Cai Wang Qingxin Guan Wei Li | 2023 | Journal of Energy Chemistry2023，，4： | 1 |
| 2 | Physical conversion and superposition of optical skyrmion topologies显示文摘Optical skyrmions are quasiparticles with nontrivial topological textures that have significant potential in optical information processing,transmission,and storage.Here,we theoretically and experimentally achieve the conversion of optical skyrmions among Néel,Bloch,intermediate skyrmions,and bimerons by polarization devices,where the fusion and annihilation of optical skyrmions are demonstrated accordingly.By analyzing the polarization pattern in Poincarébeams,we reveal the skyrmion topology dependence on the device,which provides a pathway for the study of skyrmion interactions.A vectorial optical field generator is implemented to realize the conversion and superposition experimentally,and the results are in good agreement with the theoretical predictions.These results enhance our comprehension of optical topological quasiparticles,which could have a significant impact on the transfer,storage,and communication of optical information. | HOUAN TENG JINZHAN ZHONG JIAN CHEN XINRUI LEI QIWEN ZHAN | 2023 | Photonics Research2023，11，12： | 0 |
