| 1 | Spatial-temporal Evolution Characteristics and Decoupling Analysis of Influencing Factors of China’s Aviation Carbon Emissions显示文摘The aviation industry has become one of the top ten greenhouse gas emission industries in the world. China’s aviation carbon emissions continue to increase, but the analysis of its influencing factors at the provincial level is still incomplete. This paper firstly uses Stochastic Impacts by Regression on Population, Affluence and Technology model(STIRPAT) model to analyze the time series evolution of China’s aviation carbon emissions from 2000 to 2019. Secondly, it uses the Logarithmic Mean Divisia Index(LDMI) model to analyze the influencing characteristics and degree of four factors on China’s aviation carbon emissions, which are air transportation revenue, aviation route structure, air transportation intensity and aviation energy intensity. Thirdly, it determines the various factors’ influencing direction and evolution trend of 31 provinces’ aviation carbon emissions in China(not including Hong Kong, Macao, Taiwan of China due to incomplete data). Finally, it derives the decoupling effort model and analyzes the decoupling relationship and decoupling effort degree between air carbon emissions and air transportation revenue in different provinces. The study found that from 2000 to2019, China’s total aviation carbon emissions continued to grow, while the growth rate of aviation carbon emissions showed a fluctuating downward trend. Air transportation revenue and aviation route structure promote the growth of total aviation carbon emissions, and air transportation intensity and aviation energy intensity have a restraining effect on the growth of total aviation carbon emissions. The scope of negative driving effect of air transportation revenue and air transportation intensity on total aviation carbon emissions in various provinces has increased. While the scope of positive driving influence of aviation route structure on total aviation carbon emissions of various provinces has increased, aviation energy intensity mainly has negative driving influence on total aviation carbon emissions of each province. Overall, the emission reduction trend in the areas to the west and north of the Qinling-Huaihe River Line is obvious. The decoupling mode between air carbon emissions and air transportation revenue in 31 provinces is mainly expansion negative decoupling.The air transportation intensity effect shows strong decoupling efforts in most provinces, the decoupling effort of aviation route structure effect and aviation energy intensity effect is not prominent. | HAN Ruiling LI Lingling ZHANG Xiaoyan LU Zi ZHU Shaohua | 2022 | Chinese Geographical Science2022，32，2： | 5 |
| 2 | Bismuth doped lead-free two-dimensional tin based halide perovskite single crystals显示文摘Heterovalent-metal doping is an efficient tool to tune the optoelectronic properties of the famous halide perovskites.Previous studies have focused on the heterovalent-doping in three-dimensional(3D) halide perovskites.However, there is a lack of such doping in two-dimensional perovskites which possess unique optoelectronic properties and improved chemical stability as compared to 3D analogues.Here, we present successful doping of Bismuth into the lattice of lead-free, two-dimensional perovskite PEA2SnBr4 single crystals.Structural characterizations demonstrate that the doped crystals possess identical crystal structure and layered morphology with the pristine one.Intriguingly, we find the PL peak and spectral shape can be tailored by tuning the concentration of Bi dopants.Femtosecond transient absorption spectroscopy is performed to understand the underlying mechanism related to tunable PL behaviors, and a clear picture of the Bismuth-doping impact is provided. | Ruiling Zhang Xin Mao Pengfei Cheng Yang Yang Songqiu Yang Tuerdi Wumaier Weiqiao Deng Keli Han | 2019 | Journal of Energy Chemistry2019，28，9： | 2 |

| 6 | Regulation of excitation energy transfer in Sb-alloyed Cs_(4)MnBi_(2)Cl_(12) perovskites for efficient CO_(2) photoreduction to CO and water oxidation toward H_(2)O_(2)显示文摘Lead(Pb)-free halide perovskites have recently attracted increasing attention as potential catalysts for CO_(2) photoreduction to CO due to their potential to capture solar energy and drive catalytic reaction.However,issues of the poor charge transfer still remain one of the main obstacles limiting their performance due to the overwhelming radiative and nonradiative charge-carrier recombination losses.Herein,Pb-free Sb-alloyed all-inorganic quadruple perovskite Cs_(4)Mn(Bi_(1-x)Sb_(x))_(2)Cl_(12)(0≤x≤1)is synthesized as efficient photocatalyst.By Sb alloying,the undesired relaxation of photogenerated electrons from conduction band to emission centers of[MnCl6]^(4-)is greatly suppressed,resulting in a weakened PL emission and enhanced charge transfer for photocatalyst.The ensuing Cs_(4)Mn(Bi_(1-x)Sb_(x))_(2)Cl_(12) photocatalyst accomplishes efficient conversion of CO_(2)into CO,accompanied by a surprising production of H_(2)O_(2),a high valueadded product associated with water oxidation.By optimizing Sb^(3+) concentration,a high CO evolution rate of 35.1μmol g^(-1)h^(-1)is achieved,superior to most other Pb and Pb-free halide perovskites.Our findings provide new insights into the mixed-cation alloying strategies for improved photocatalytic performance of Pb-free perovskites and shed light on the rational design of robust band structure toward efficient energy transfer. | Haiwen Wei Zhen Li Honglei Wang Yang Yang Pengfei Cheng Peigeng Han Ruiling Zhang Feng Liu Panwang Zhou Keli Han | 2023 | Journal of Energy Chemistry2023，，7： | 0 |
| 7 | Tuning Exciton Recombination Pathways in Inorganic Bismuth-Based Perovskite for Broadband Emission显示文摘Single-component emitters with broadband emission are attractive but challenging for illumination and display applications.The two-dimensional organic-inorganic hybrid perovskites have exhibited outstanding broad emission property due to low electronic dimensionality and strong exciton-phonon coupling.However,few layered all-inorganic lead-free perovskites with broadband emission have been explored,and the explicit mechanism of exciton recombination in them also needs in-depth understanding.Herein,the inorganic bismuth-based perovskite Cs3Bi2Br9 achieves the stable broadband emission under ambient temperature and pressure by tuning the exciton recombination pathways via antimony(Sb)doping,and the photoluminescence quantum yield(PLQY)realizes an enhancement from 2.9%to 15.9%.The photoluminescence excitation(PLE)spectra indicate that the doped Sb introduces newly extrinsic self-trapped states.The incorporation of Sb promotes the transfer of free excitons(FEs)to extrinsic self-trapped excitons(STEs)observed from Sb content-dependent steady-state PL spectra and,meanwhile,reduces the nonradiative recombination of the generated extrinsic STEs,which are primarily responsible for the remarkably enhanced broad emission.Furthermore,femtosecond transient absorption results elucidate a clear exciton dynamics,in which the transition from FEs to STEs might arise through the gradient energy levels,and finally extrinsic STEs at various energy states contribute to the broadband emission. | Ming Shi Bin Yang Siping Liu Ruiling Zhang Keli Han Can Li Rengui Li | 2022 | Energy Material Advances2022，，1： | 0 |
