| 1 | Improving the activity and stability of Ni-based electrodes for solid oxide cells through surface engineering:Recent progress and future perspectives显示文摘Solid oxide cells(SOCs)have attracted great attention in the past decades because of their high conversion efficiency,low environmental pollution and diversified fuel options.Nickel-based catalysts are the most widely used fuel electrode materials for SOCs due to the low price and high activity.However,when hydrocarbon fuels are employed,nickel-based electrodes face serious carbon deposition challenges,leading to a rapid decline of cell performance.Great efforts have been devoted to understanding the occurrence of the coking reaction,and to improving the stability of the electrodes in hydrocarbon fuels.In this review,we summarize recent research progress of utilizing surface modification to improve the stability and activity of Ni-based electrodes for SOCs by preventing carbon coking.The review starts with a briefly introduction about the reaction mechanism of carbon deposition,followed by listing several surface modification technologies and their working principles.Then we introduce representative works using surface modification strategies to prevent carbon coking on Ni-based electrodes.Finally,we highlight future direction of improving electrode catalytic activity and anti-coking performance through surface engineering. | Junxian Pan Yongjian Ye Mengzhen Zhou Xiang Sun Yihan Ling Keiji Yashiro Yan Chen | 2021 | Materials Reports(Energy)2021，1，2： | 2 |

| 6 | New two-layer Ruddlesden-Popper cathode materials for protonic ceramics fuel cells显示文摘New two-layer Ruddlesden-Popper(RP)oxide La_(0.25)Sr_(2.75)FeNiO_(7-δ)(LSFN)in the combination of Sr_(3)Fe_(2)O_(7-δ) and La_(3)Ni_(2)O_(7-δ) was successfully synthesized and studied as the potential active single-phase and composite cathode for protonic ceramics fuel cells(PCFCs).LSFN with the tetragonal symmetrical structure(IMmmm)is confinned,and the co-existence of Fe^(3+)/Fe^(4+) and Ni^(3+)/Ni^(2+) couples is demonstrated by X-ray photoelectron spectrometer(XPS)analysis.The LSFN conductivity is apparently enhanced after Ni doping in Fe-site,and nearly three times those of Sr_(3)Fe_(2)O_(7-δ),which is directly related to the carrier concentration and conductor mechanism.Importantly,anode supported PCFCs using LSFN-BaZr_(0.1)Ce_(0.7)Y_(0.2)O_(3-δ)(LSFN-BZCY)composite cathode achieved high power density(426 mW·cm^(-2) at 650℃)and low electrode interface polarization resistance(0.26Ω·cm^(2)).Besides,distribution of relaxation time(DRT)function technology was further used to analyse the electrode polarization processes.The observed three peaks(Pl,P2,and P3)separated by DRT shifted to the high frequency region with the decreasing temperature,suggesting that the charge transfer at the electrode-electrolyte interfaces becomes more difficult at reduced temperatures.Preliminary results demonstrate that new two-layer RP phase LSFN can be a promising cathode candidate for PCFCs. | Yihan LING Tianming GUO Yangyang GUO Yang YANG Yunfeng TIAN Xinxin WANG Xuemei OU Peizhong FENG | 2021 | Journal of Advanced Ceramics2021，10，5： | 1 |
| 7 | Interactions between hydrocarbon-bearing fluids and calcite in fused silica capillary capsules and geological implications for deeply-buried hydrocarbon reservoirs显示文摘During the burial processes of deep/ultra-deep hydrocarbon reservoirs,the interactions between hydrocarbon-bearing fluids and reservoirs significantly affect the quality evolution of hydrocarbons and reservoirs;thus,this topic requires further investigation.In this study,the continuous evolution and the coupling mechanisms in various anhydrous and hydrous nC_(16)H_(34)-(water)-(calcite)systems in fused silica capillary capsules(FSCCs)were investigated using laser Raman spectroscopy,fluorescence color analysis,and fluorescence spectroscopy,and the mineral alterations were analyzed using scanning electron microscopy(SEM).The experimental results show that extensive organic-inorganic interactions occur in the systems if water is present,and different inorganic components have different effects on hydrocarbon degradation.Distilled water promotes freeradical thermal cracking and steps oxidation,forming more low-molecular-weight hydrocarbons,CO_(2),and organic acids(e.g.,acetic acids)but suppresses the free-radical cross-linking,generating less high-molecular-weight hydrocarbons.However,in the presence of CaCl_(2) water,the yields of hydrocarbon gases are lower than in the distilled water system because high concentrations of Ca ions inhibit the generation of free radicals.Calcites,which exhibit different surface reactivities in different fluid conditions,affect hydrocarbon degradation in different ways.In the anhydrous nC16H34-calcite system,calcites promote the generation of both hydrocarbon gases and high-molecular-weight hydrocarbons.In contrast,in the hydrous nC16H34-distilled(CaCl_(2))watercalcite system,calcites promote the generation of hydrocarbon gases and suppress the generation of high-molecular-weight hydrocarbons.Calcite also reacts with organic acids via surface reactions to form secondary pores.Therefore,except for the formation temperature and pressure,organic-inorganic interactions are controlled by multiple factors,such as the water saturation,water type,water salinity,and the mineral content,resulting in different evolutions of the hydrocarbon degradation and reservoir properties. | Zihao JIN Guanghui YUAN Yingchang CAO Keyu LIU Yanzhong WANG Jianye SUN Xiluo HAO Ling ZHOU Yihan WEI Shuqi WU | 2022 | Science China Earth Sciences2022，65，2： | 0 |
| 8 | Robust Joule-heating ceramic reactors for catalytic CO oxidation显示文摘Joule-heating reactors have the higher energy efficiency and product selectivity compared with the reactors based on radiative heating.Current Joule-heating reactors are constructed with electrically-conductive metals or carbon materials,and therefore suffer from stability issue due to the presence of corrosive or oxidizing gases during high-temperature reactions.In this study,chemicallystable and electrically-conductive(La_(0.80)Sr_(0.20))_(0.95)FeO_(3)(LSF)/Gd_(0.1)Ce_(0.9)O_(2)(GDC)ceramics have been used to construct Joule-heating reactors for the first time.Taking the advantage of the resistance decrease of the ceramic reactors with temperature increase,the ceramic reactors heated under current control mode achieved the automatic adjustment of heating to stabilize reactor temperatures.In addition,the electrical resistance of LSF/GDC reactors can be tuned by the content of the highconductive LSF in composite ceramics and ceramic density via sintering temperature,which offers flexibility to control reactor temperatures.The ceramic reactors with dendritic channels(less than 100μm in diameter)showed the catalytic activity for CO oxidation,which was further improved by coating efficient MnO_(2)nanocatalyst on reactor channel wall.The Joule-heating ceramic reactors achieved complete CO oxidation at a low temperature of 165℃.Therefore,robust ceramic reactors have successfully demonstrated effective Joule heating for CO oxidation,which are potentially applied in other high-temperature catalytic reactions. | Fangsheng LIU Zhibo ZHAO Yuyao MA Yi GAO Jiajie LI Xun HU Zhengmao YE Yihan LING Dehua DONG | 2022 | Journal of Advanced Ceramics2022，11，7： | 0 |
| 9 | Random Terpolymer Based on Simple Siloxane-functionalized Thiophene Unit Enabling High-performance Non-fullerene Organic Solar Cells显示文摘Incorporation of siloxane-functionalized units into polymers backbone has proven to be an efficient strategy to improve photovoltaic performance. In this work, a low-cost siloxane-containing unit was developed to construct a series of terpolymers, and the effects of siloxane on the polymer performance were systematically studied. Different contents of thiophene containing siloxane-functionalized side chain were introduced into PM6 to obtain a series of polymers(PM6, PM6-SiO-10, PM6-SiO-20 and PM6-SiO-30). The siloxane-functionalized side chains in polymers have only a slight effect on the absorption behavior and frontier molecular orbitals. However, when the siloxane content increased, the terpolymers' aggregation property decreased and the temperature-dependency increased, leading to improved donor-acceptor compatibility. The power conversion efficiency(PCE) based on PM6:Y6, PM6-SiO-20:Y6 and PM6-SiO-30:Y6 devices was 15.64%, 16.03% and 15.82%, respectively. In comparison, the active layer based on PM6-SiO-10:Y6 exhibits the most appropriate phase separation morphology, resulting in effective exciton dissociation, more balanced hole-electron transport and less recombination. Consequently, the highest PCE of 16.69% with an outstanding shortcircuit current density of 26.96 mA·cm-2 was obtained, which are one of the highest values for siloxane-functionalized polymer-based devices.This work demonstrates that finely controlling the content of siloxane-functionalized thiophene is beneficial for obtaining high-performance terpolymer donors and provides a novel and low-cost method to improve photovoltaic performance. | Fuliang Cheng Shiting Lai Yihan Zhang Ling Xue Xinxin Xia Peipei Zhu Xinhui Lu Xunfan Liao Yiwang Chen | 2024 | Chinese Journal of Polymer Science2024，42，3： | 0 |
