| 1 | High-Performance and Hysteresis-Free Perovskite Solar Cells Based on Rare-Earth-Doped SnO_(2) Mesoporous Scaffold显示文摘Tin oxide(SnO_(2)),as electron transport material to substitute titanium oxide(TiO_(2))in perovskite solar cells(PSCs),has aroused wide interests.However,the performance of the PSCs based on SnO_(2) is still hard to compete with the TiO_(2)-based devices.Herein,a novel strategy is designed to enhance the photovoltaic performance and long-term stability of PSCs by integrating rare-earth ions Ln^(3+)(Sc^(3+),Y^(3+),La^(3+))with SnO_(2) nanospheres as mesoporous scaffold.The doping of Ln promotes the formation of dense and large-sized perovskite crystals,which facilitate interfacial contact of electron transport layer/perovskite layer and improve charge transport dynamics.Ln dopant optimizes the energy level of perovskite layer,reduces the charge transport resistance,and mitigates the trap state density.As a result,the optimized mesoporous PSC achieves a champion power conversion efficiency(PCE)of 20.63%without hysteresis,while the undoped PSC obtains an efficiency of 19.01%.The investigation demonstrates that the rare-earth doping is low-cost and effective method to improve the photovoltaic performance of SnO_(2)-based PSCs. | Qiyao Guo Jihuai Wu Yuqian Yang Xuping Liu Zhang Lan Jianming Lin Miaoliang Huang Yuelin Wei Jia Dong Jinbiao Jia Yunfang Huang | 2019 | Research2019，，1： | 3 |

| 3 | Enhanced N_(2)-to-NH_(3)conversion efficiency on Cu3P nanoribbon electrocatalyst显示文摘Ambient electroreduction of nitrogen(N_(2))is considered as a green and feasible approach for ammonia(NH_(3))synthesis,which urgently demands for efficient electrocatalyst.Morphology has close relationship with catalytic activity of heterogeneous catalysts.Nanoribbon is attractive nanostructure,which possesses the flexibility of one-dimensional nanomaterials,the large surface area of two-dimensional nanomaterials,and lateral size confinement effects.In this work,Cu_(3)P nanoribbon is proposed as a highly efficient electrocatalyst for N_(2)-to-NH_(3)conversion under benign conditions.When measured in N_(2)-saturated 0.1 M HCl,such Cu_(3)P nanoribbon achieves high performance with an excellent Faradaic efficiency as high as 37.8%and a large yield of 18.9μg·h^(−1)·mgcat.−1 at−0.2 V.It also demonstrates outstanding stability in long-term electrolysis test at least for 45 h. | Qian Liu Yiting Lin Shuang Gu Ziqiang Cheng Lisi Xie Shengjun Sun Longcheng Zhang Yongsong Luo Abdulmohsen Ali Alshehri Mohamed SHamdy Qingquan Kong Jiahong Wang Xuping Sun | 2022 | Nano Research2022，15，8： | 1 |

| 5 | Bi nanoparticles/carbon nanosheet composite:A high-efficiency electrocatalyst for NO reduction to NH_(3)显示文摘Electrochemical reduction of NO offers us an attractive alternative to traditional selective catalytic reduction process for harmful NO removal and simultaneous NH_(3)production,but it requires efficient electrocatalyst to enable the NO reduction reaction with high selectivity.Here,we report on the development of Bi nanoparticles/carbon nanosheet composite(Bi@C)for highly effective NO reduction electrocatalysis toward selective NH_(3)formation.Such Bi@C catalyst attains an impressive NH_(3)yield of 1,592.5μg·h^(−1)·mgcat.^(−1)and a high Faradaic efficiency as high as 93%in 0.1 M Na_(2)SO_(4)electrolyte.Additionally,it can be applied as efficient cathode materials for Zn–NO battery to reduce NO to NH_(3)with high electricity generation. | Qian Liu Yiting Lin Luchao Yue Jie Liang Longcheng Zhang Tingshuai Li Yongsong Luo Meiling Liu Jinmao You Abdulmohsen Ali Alshehri Qingquan Kong Xuping Sun | 2022 | Nano Research2022，15，6： | 0 |
| 6 | Multiple-Constraint-Aware RWA Algorithms Based on a Comprehensive Evaluation Model:Use in Wavelength-Switched Optical Networks显示文摘Because of explosive growth in Internet traffic and high complexity of heterogeneous networks,improving the routing and wavelength assignment (RWA) algorithm in underlying optical networks has become very important.Where there are multiple links between different the node pairs,a traditional wavelength-assignment algorithm may be invalid for a wavelength-switched optical networks (WSON) that has directional blocking constraints.Also,impairments in network nodes and subsequent degradation of optical signals may cause modulation failure in the optical network.In this paper,we propose an RWA algorithm based on a novel evaluation model for a WSON that has multiple constraints.The algorithm includes comprehensive evaluation model (CEM) and directional blocking constraint RWA based on CEM (DB-RWA).Diverse constraints are abstracted into various constraint conditions in order to better assign routing and wavelength.We propose using the novel CEM to optimize routing according to an assessed value of constraints on transmission performance.This eliminates the effects of physical transmission impairments in a WSON.DB-RWA based on CEM abstracts directional blocking conditions in multiple links between network nodes into directional blocking constraints.It also satisfies rigorous network specifications and provides flexibility,scalability,and first-fit rate for the backbone,especially in multiple links between WSON nodes. | Hui Yang YongliZhao Shanguo Huang Dajiang Wang Xuping Cao Xuefeng Lin | 2012 | ZTE Communications2012，10，3： | 0 |
| 7 | Effect of CeO_(2) nanoparticle sizes on catalytic performances of sulfated CeO_(2)/Al_(2)O_(3) catalyst in NH_(3)-SCR reaction显示文摘The sulfated CeO_(2)/Al_(2)O_(3) catalysts with different sizes of CeO_(2)nanoparticles were prepared by using pure H_2O or acetic acid solution as impregnation solvent, and the influence of sizes of CeO_(2) nanoparticles on the catalytic performances of the sulfated CeO_(2)/Al_(2)O_(3) catalyst was studied. The catalytic performance tests show that the sulfated CeO_(2)/Al_(2)O_(3) catalyst using acetic acid solution as impregnation solvent has better catalytic activity and the resistance to K+poisoning than the sulfated CeO_(2)/Al_(2)O_(3) catalyst using pure H_(2)O as impregnation solvent. The excellent catalytic performances can be ascribed to the smaller sizes of CeO_(2) nanoparticles in CeO_(2)/Al_(2)O_(3) catalyst using acetic acid solution, which results in larger amount of adsorbed sulfate species, surface acid sites, surface active oxygen species and excellent redox property. These features are helpful for improving the catalytic performances of sulfated CeO_(2)/Al_(2)O_(3) catalyst using smaller amount of CeO_(2) to cut the costs. | Zhenghua Hu Dongqi An Lei Zhang Xuping Wang Siyong Fang Xinyun Tian Liu Qiu Jingfang Sun Tingzhen Li Lin Dong | 2024 | Journal of Rare Earths2024，42，3： | 0 |
