| 1 | Room-temperature conversion of ethane and the mechanism understanding over single iron atoms confined in graphene显示文摘The catalytic conversion of ethane to high value-added chemicals is significantly important for utilization of hydrocarbon resources.However, it is a great challenge due to the typically required high temperature(> 400 ℃) conditions.Herein, a highly active catalytic conversion process of ethane at room temperature(25 ℃) is reported on single iron atoms confined in graphene via the porphyrin-like N4-coordination structures.Combining with the operando time of flight mass spectrometer and density functional theory calculations, the reaction is identified as a radical mechanism, in which the C–H bonds of the same C atom are preferentially and sequentially activated, generating the value-added C2 chemicals, simultaneously avoiding the over-oxidation of the products to CO2.The in-situ formed O–FeN4–O structure at the single iron atom serves as the active center for the reaction and facilitates the formation of ethyl radicals.This work deepens the understanding of alkane C–H activation on the FeN4 center and provides the reference in development of efficient catalyst for selective oxidation of light alkane. | Suheng Wang Haobo Li Mengqi He Xiaoju Cui Lei Hua Haiyang Li Jianping Xiao Liang Yu N.Pethan Rajan Zhaoxiong Xie Dehui Deng | 2019 | Journal of Energy Chemistry2019，28，9： | 1 |

| 3 | Ensemble Transform Sensitivity Method for Adaptive Observations显示文摘The Ensemble Transform(ET) method has been shown to be useful in providing guidance for adaptive observation deployment.It predicts forecast error variance reduction for each possible deployment using its corresponding transformation matrix in an ensemble subspace.In this paper,a new ET-based sensitivity(ETS) method,which calculates the gradient of forecast error variance reduction in terms of analysis error variance reduction,is proposed to specify regions for possible adaptive observations.ETS is a first order approximation of the ET;it requires just one calculation of a transformation matrix,increasing computational efficiency(60%-80%reduction in computational cost).An explicit mathematical formulation of the ETS gradient is derived and described.Both the ET and ETS methods are applied to the Hurricane Irene(2011) case and a heavy rainfall case for comparison.The numerical results imply that the sensitive areas estimated by the ETS and ET are similar.However,ETS is much more efficient,particularly when the resolution is higher and the number of ensemble members is larger. | Yu ZHANG Yuanfu XIE Hongli WANG Dehui CHEN Zoltan TOTH | 2016 | Advances in Atmospheric Sciences2016，33，1： | 1 |

| 8 | Mechanically induced Cu active sites for selective C–C coupling in CO_(2)electroreduction显示文摘Developing a convenient method to endow bulk Cu-based electrode with high activity of electrocatalytic CO_(2)reduction reaction(CO_(2)RR)to multicarbon(C_(2+))products is desirable but challenging.Herein,for the first time,we report that mechanical polishing induces highly reactive Cu sites for selective C-C coupling in CO_(2)RR.We find that mechanical polishing could endow Cu foil with abundant nanocavity surface structure,which efficiently confines the carbonaceous intermediates to enhance the probability of C-C coupling reaction.By confining the carbonaceous intermediates with Cu nanocavity,the as-prepared electrode delivers a Faradaic efficiency toward C_(2+)products of 65.7%at-1.3 V vs.RHE,which is enhanced up to 1.7 folds compared with that of commercial Cu foil.This work provides a new method to enable Cu foil with high activity of CO_(2)RR to C_(2+)products. | Zhao Chen Yao Song Zhenyu Zhang Yafeng Cai Huan Liu Wenxiang Xie Dehui Deng | 2022 | Journal of Energy Chemistry2022，31，11： | 0 |
