1The causes and processes responsible for rocky desertification in karst areas of southern China显示文摘The karst region of southern China is a fragile ecological zone with widespread rocky desertification. This paper describes the rocky desertification occurring in this region in terms of both natural and anthropogenic factors. During geological time periods, the region's changing environment governed the natural rocky desertification processes, whereas during historical and modern times, anthropogenic processes have been superimposed on these natural processes. Human activities have accelerated and exacerbated rocky desertification. The period from the beginning to the middle of the Qing dynasty was an important transitional period in which human activities began to exert a particularly strong influence on rocky desertification. Since then, the effect of anthropogenic factors has increasingly exceeded the effect of natural factors. The rocky desertification process in southern China's karst region combines surface ecological processes (including vegetation degradation and loss, soil erosion, surface water loss, and bedrock solution) with a reduction of the land's biological productivity, leading to degradation that produces rocky desert. Controlling rocky desertification requires comprehensive development of sustainable agriculture and economic development that provides employment alternatives to agriculture and thereby promotes the rehabilitation of rocky desertified land.Sen Li 1,2*, XingHu Wei 1, JinGuo Huang 1, XiZhi Wang 1, GuanYao Lu 1, HuiXia Li 11.

10Efficient synthesis of cyclic carbonates under atmospheric CO_(2) by DMAP-based ionic liquids: the difference of inert hydrogen atom and active hydrogen atom in cation显示文摘The coupling reaction of carbon dioxide(CO_(2)) and epoxides is one of the most efficient pathways to achieve the carbon balance.However,to accomplish it under the mild conditions,especially under the atmospheric pressure,is still a perplexing problem.Three novel ionic liquids(ILs),[DMAPBrPC][TMGH],[DMAPBrPC][DBUH],and[DMAPBrPC][BTMA],are designed and synthesized.All of them display the excellent catalytic activity for the title reaction achieving the yield over 96.6% under the atmospheric CO_(2) pressure at 60℃.Interestingly,[DMAPBrPC][BTMA]with the inert hydrogen atom in cation exhibits the superior catalytic activity as compared to other two ILs with the protic hydrogen atom in cation along with the same anion.The active hydrogen atom in[DMAPBrPC][TMGH]and[DMAPBrPC][DBUH]would impede the–COO^(-)group to absorb CO 2,which is an unfavorable item for the reaction.Moreover,the strong hydrogen bond in[DMAPBrPC][TMGH]and[DMAPBrPC][DBUH]would lessen the nucleophilic ability of Br^(-) anion resulting in the inferior catalytic performance,which is further confirmed by the density functional theory(DFT)calculations.The cation without the active hydrogen atom could also be employed to design the ILs with the excellent catalytic feature when it is combined with the suitable anion.Zhengkun Zhang Jinya Li Guanyao Yu Chao Zeng Menglong Wang Susu Huang Li Wang Jinglai Zhang 2023Green Chemical Engineering2023,4,3:0
11Double interface regulation: Toward highly stable lithium metal anode with high utilization显示文摘The undesirable Li dendrite growth and other knock-on issues have signifi-cantly plagued the application of Li metal anodes(LMAs).Herein,we report that the synergistic regulation of double interfaces adjacent to the metallic Li anode can effectively prevent the dendritic Li growth,significantly improving the cycling performance of LMAs under harsh conditions including high cur-rent density and high depth of discharge.Thorough comparison of electrolytes demonstrated that 1 M lithium bis(fluorosulfonyl)imide(LiFSI)in 1,2-dimethoxyethane(DME)can yield a robust and lithiophobic LiF-rich upper interface(solid electrolyte interphase).Besides,the Sb-based buffer layer forms a lithiophilic lower interface on current collector.The synergy of the upper and lower interfacial engineering plays an important role for outstanding cyclability of LMAs.Consequently,the plating/stripping of Li can be stably repeated for 835 and 329 cycles with an average Coulombic efficiency(CE)above 99%at 1 and 3 mA h cm?2,respectively.Surprisingly,the Li||Li symmetric cell can even withstand the baptism of current density up to 20 mA cm?2.The excellent performance validates that the facile synergistic regulating of interfaces adjacent to the metallic Li anode provides an effective pathway to stabilize LMAs.Guanyao Wang Ming Zhu Ying Zhang Chan Song Xiaolong Zhu Zhongyi Huang Yuanjun Zhang Fangfang Yu Gang Xu Minghong Wu Hua-Kun Liu Shi-Xue Dou Chao Wu 2022InfoMat2022,4,7:0
12An in-situ generated Bi-based sodiophilic substrate with high structural stability for high-performance sodium metal batteries显示文摘Sodium(Na)metal anode exhibits a potential candidate in next-generation rechargeable batteries owing to its advantages of high earth abundance and low cost.Unfortunately,the practical development of sodium metal batteries is inherently plagued by challenges such as the side reactions and the growth of Na dendrites.Herein we report a highly stable Bi-based“sodiophilic”substrate to stabilize Na anode,which is created by in-situ electrochemical reactions of 3D hierarchical porous Bi_(2)MoO_(6)(BMO)microspheres.BMO is initially transformed into the Bi“nanoseeds”embedded in the Na-Mo-O matrix.Subsequently,the Bi nanoseeds working as preferential nucleation sites through the formation of BiNa alloy enable the non-dendritic Na deposition.The asymmetric cells based on such BMO-based substrate can deliver a long-term cycling for 600 cycles at a large capacity of 4 m Ah cm^(-2) and for 800 cycles at a high current density of 10 m A cm^(-2).Even at a high depth of discharge(66.67%),the Na-predeposited BMO(Na@BMO)electrodes can cycle for more than 1600 h.The limited Na@BMO anodes coupled with the Na_(3)V_(2)(PO_(4))_(3) cathodes(N/P ratio of 3)in full cells also show excellent electrochemical performance with a capacity retention of about 97.4%after 1100 cycles at 2 C.Lulu Li Ming Zhu Guanyao Wang Fangfang Yu Liaoyong Wen Hua-Kun Liu Shi-Xue Dou Chao Wu 2022Journal of Energy Chemistry2022,31,8:0
