Exclusive responsiveness to ultraviolet light (~3.2 eV) and high photogenerated charge recom.ination rate are the two prim.ry.drawbacks of pure TiO_(2). We com.ined N-doped graphene quantum.dots (N-GQDs), m.rphology.regulation, and heterojunction construction strategies to sy.thesize N-GQD/N-doped TiO_(2)/P-doped porous hollow g-C_(3)N_(4) nanotube (PCN) com.osite photocataly.ts (denoted as G-TPCN). The optim.l sam.le (G-TPCN doped with 0.1wt% N-GQD, denoted as 0.1% G-TPCN) exhibits significantly.enhanced photoabsorption, which is attributed to the change in bandgap caused by.elem.ntal doping (P and N), the im.roved light-harvesting resulting from.the tube structure, and the upconversion effect of N-GQDs. In addition, the internal charge separation and transfer capability.of0.1% G-TPCN are dram.tically.boosted, and its carrier concentration is 3.7, 2.3, and 1.9 tim.s that of N-TiO_(2), PCN, and N-TiO_(2)/PCN(TPCN-1), respectively. This phenom.non is attributed to the form.tion of Z-schem. heterojunction between N-TiO_(2) and PCNs, the excellent electron conduction ability.of N-GQDs, and the short transfer distance caused by.the porous nanotube structure. Com.ared with those of N-TiO_(2), PCNs, and TPCN-1, the H2 production activity.of 0.1%G-TPCN under visible light is enhanced by.12.4, 2.3, and 1.4tim.s, respectively. and its ciprofloxacin (CIP) degradation rate is increased by.7.9, 5.7, and 2.9 tim.s, respectively. The optim.zed perform.nce benefits from.excellent photoresponsiveness and im.roved carrier separation and m.gration efficiencies. Finally. the photocataly.ic m.chanism.of 0.1% G-TPCN and five possible degradation pathway. of CIP are proposed. This study.clarifies the m.chanism.of m.ltiple m.dification strategies to sy.ergistically.im.rove the photocataly.ic perform.nce of 0.1% G-TPCN and provides a potential strategy.for rationally.designing novel photocataly.ts for environm.ntal rem.diation and solar energy.conversion.

m.gnetized m.gm. intrusions being sources of a weak and a strong lunar m.gnetic anom.ly.revealed by.3D distribution of m.gnetization

引用

Earth and Planetary.Phy.ics 2024年第5期8卷 711-727页

作者： Hongy. Wang Shuo yao ZeLin Li Liang Hui Guo Jing y.ng ChangLi yao y.an Fang ZhaoJin Rong School of Geophy.ics and Inform.tion Technology Research Center of Lunar and Planetary Remote Sensing Exploration China University of Geosciences (Beijing) Key.Laboratory.of Intraplate Volcanoes and Earthquakes (China University.of Geosciences Beijing) Ministry of Education Hebei University.of Engineering Key.Laboratory.of Earth and Planetary.Phy.ics Institute of Geology and Geophysics Chinese Academy of Sciences

In this work, we aim.to investigate the origin of the m.gnetic carriers in the lunar crust and the intensity.of the ancient dy.am. field. The m.gnetization and depth range of m.gnetic carriers are studied under a weak and a strong m.gnetic anom.ly.in m.re Tranquillitatis and in Oceanus Procellarum. respectively. where the surface ages are 3.6 and 3.3 billion y.ars. A sophisticated threedim.nsional am.litude inversion software program.from.a geophy.ical survey.is used to reconstruct the distributions of m.gnetization in the lunar crust. Because no globally.m.asured surface m.gnetic field exists for the m.on, a crustal m.gnetic anom.ly.m.del with a grid resolution of 0.2° is used. The depth range of the m.gnetic source is fixed by.the boundary.identified by.a relative criterion, which is 20%of the recovered m.xim.m.m.gnetization. The central burial depths of the m.gnetic carriers are approxim.tely.15 km.and 25 km.under Reiner Gam.a and m.re Tranquillitatis, respectively. The volum.s of the two m.gnetic sources are at scales of 104 and 105 km.,respectively. The aforem.ntioned differences m.y.im.ly.a hotter crust under Reiner Gam.a than m.re Tranquillitatis by.3.3 billion *** results support the view that the m.gm. intrusions m.gnetized by.an ancient m.gnetic field could be the origin of m.gnetic anom.lies under Reiner Gam.a and m.re Tranquillitatis. Com.ared with previous works, the m.xim.m.m.gnetization of 3 A/m.under Reiner Gam.a supports the intensity.of the field being several m.croteslas.
