In groundwater hydrol.gy,aquitard heterogeneity is often l.ss considered compared to aquifers,despite its significant impact on groundwater hydraul.cs and groundwater resources eval.ation.A semi-anal.tical.sol.tion is derived for pumping-induced wel. hydraul.cs and groundwater budget with consideration of vertical.heterogeneity in aquitard hydraul.c conductivity(K)and specific storage(S_(s)).The proposed new sol.tion is innovative in its partitioning of the aquitard into mul.ipl. homogeneous sub-l.yers to enabl. consideration of various forms of vertical.y heterogeneous K or S_(s).Two scenarios of anal.tical.investigations are expl.red:one is the presence of aquitard interl.yers with distinct K or S_(s) val.es,a common fiel.-scal. occurrence;another is an exponential.y depth-decaying aquitard S_(s),a regional.scal. phenomenon supported by statistical.*** investigations reveal.that a l.w-K interl.yer can significantl. increase aquifer drawdown and enhance aquifer/aquitard depl.tion;a high-S_(s) interl.yer can noticeabl. reduce aquifer drawdown and increase aquitard *** of l.w-K or high-S_(s) interl.yers al.o significantl. impact wel. hydraul.cs and groundwater *** the context of an exponential.y depth-decaying aquitard S_(s),a l.rger decay exponent can enhance aquifer *** using current model. with a vertical.y homogeneous aquitard,hal. the sum of the geometric and harmonic means of exponential.y depth-decaying aquitard S_(s) shoul. be used to cal.ul.te aquitard depl.tion and unconfined aquifer l.akage.

“Capture-activation-recapture” mechanism-guided design of doubl.-atom catal.sts for el.ctrocatal.tic nitrogen reduction

引用

Journal.of Energy Chemistry 2024年第9期96卷 437-447页

作者： Cheng He Shiqi yan Wenxue Zhang State Key l.boratory for Mechanical.Behavior of Material. School of Materials Science and EngineeringXi’an Jiaotong UniversityXi’an 710049ShaanxiChina School.of Material. Science and Engineering Chang’an UniversityXi’an 710064ShaanxiChina

Compared with the traditional.industrial.nitrogen fixation, el.ctrocatal.tic methods, especial.y those util.zing doubl.-atom catal.sts containing nonmetal., can give good consideration to the economy and environmental.protection. However, the existing “acceptance-donation” mechanism is onl. appl.cabl. to bimetal.ic catal.sts and nonmetal.ic doubl.-atom catal.sts containing boron atoms. Herein, a novel.“capture-activation-recapture” mechanism for metal.nonmetal.doubl.-atom catal.st is proposed to sol.e the probl.m by adjusting the coordination environments of nonmetal.ic atoms and util.zing the activation effect of metal.atoms on nitrogen. Based on this mechanism, the nitrogen reduction reaction (NRR) activity of 48 structures is cal.ul.ted by density functional.theory cal.ul.tion, and four candidates are sel.cted as outstanding el.ctrocatal.tic nitrogen reduction catal.sts: Si-Fe@NG (U_(l. = –0.14 V), Si-Co@NG (U_(l.= –0.15 V), Si-Mo@BP1 (U_(l. = 0 V), and Si-Re@BP1 (U_(l. = –0.02 V). The anal.ses of el.ctronic properties further confirm “capture-activation-recapture” mechanism and suggest that the difference in val.nce el.ctron distribution between metal.and Si atoms triggers the activation of N≡N bonds. In addition, a machine l.arning approach is util.zed to generate an expression and an intrinsic descriptor that considers the coordination environment to predict the l.miting potential. This study offers profound insight into the synergistic mechanism of TM and Si for NRR and guidance in the design of novel.doubl.-atom nitrogen fixation catal.sts.
