An effective yet simple approach was developed to synthesize mesoporous PdBi nanocages for electrochemical applications. This technique relies on the subtle utilization of hydrolysis a metal salt generate precipitate cores in situ as templates navigating growth shells with assistance polymeric micelles. The are then obtained by excavating vulnerable and regulating crystals metallic skeletons. resultant exhibited excellent electrocatalytic performance toward ethanol oxidation reaction mass...
Cobalt oxides, including spinel Co3O4 and rock-salt CoO, have been widely reported as promising catalysts for oxygen reduction reaction (ORR). However, three types of cobalt ions, i.e., Co2+ in the tetrahedral site (Co2+ Td), Co3+ octahedral (Co3+ Oh), are included these roles geometric occupancy valance states remained elusive. Here, first time, we investigated effects on ORR activity by substituting Td Oh with inactive Zn2+ Al3+, respectively. The decreases order Oh, Td) < ZnCo2O4 Oh) ≪...
To construct photocatalysts with matched band alignments and intimate interfaces is crucial but challenging for photocatalysis. Herein, we the first time report a strategy modulation interface engineering to generate an efficient bifunctional photocatalyst. By interstitially doping P into g-C3N4 quantizing CoP, fabricated CoPQD/P-g-C3N4 hybrid possesses tailed heterojunction via in situ generated interfacial Co–P bonds. as noble-metal free photocatalyst displays excellent photocatalytic...
Abstract Electrode‐electrolyte interfacial modification by hydrophobic molecules represents a promising strategy for suppressing competing proton reduction in acidic electrocatalytic carbon dioxide reactions (CO 2 RR), meanwhile sacrificing extra overpotential due to increased ohmic resistance. Herein, multifunctional conductive polymer, polyaniline modified p‐aminobenzenesulfonic acid (ABSA‐polyaniline), is constructed between Cu catalyst layer and electrolyte simultaneously create an ideal...
The acoustic properties of seafloor sediments on continental slopes play a crucial role in underwater propagation, communication, and detection. To investigate the characteristics spatial distribution patterns slope, geoacoustic experiment was conducted northwestern South China Sea. covered two sections: one crossing shelf slope downslope direction, other near break along-slope direction. In situ techniques, sediment sampling, laboratory measurements were used to acquire data (such as sound...
Abstract It has long been recognized that ocean gravity waves can generate microseisms through their interactions and coupling with the solid earth. Their generation mechanisms, wave types, propagation have studied debated intensively. In this study, we focus on characteristics of in South China Sea (SCS) compare them globally observed microseisms. We use data from six bottom seismometers, 10 publicly available broadband land seismometers near SCS, a reanalyzed global height model 1 May 2012...
Water electrolysis is a clean and effective strategy for mass production of hydrogen. Iron phosphide fascinating candidate hydrogen evolution reaction (HER) among the reported Pt-free metal catalysts; however, catalytic activity FeP far behind Pt. Herein, we prepared highly efficient durable mesoporous Mn-doped (Mn-FeP) catalyst HER via facile controllable synthesis route. It manifested that Mn doping leads to improved electroactivity in wide pH range. For Mn-FeP catalyst, overpotential 69,...

Nanoporous nanoparticles with their surfaces open to reagents enable good electron/mass transport and overall resistance aggregation, thus they are significantly important in electrocatalytic applications.
Abstract Developing sufficiently effective non‐precious metal catalysts for large‐current‐density hydrogen production is highly significant but challenging, especially in low‐voltage systems. Here, we innovatively report high‐entropy alloy nanoflower array (HEANFA) electrodes with optimizable reaction pathways hydrazine oxidation‐assisted at industrial‐grade current densities. Atomic‐resolution structural analyses confirm the single‐phase solid‐solution structure of HEANFA. The HEANFA...
China has very long coastline, but special surface conditions make it difficult to conduct ground magnetic and marine geomagnetic surveys over beach–shallow sea transition areas such as mariculture areas, harbours, wharfs; a result, survey data cannot be linked continental data, giving rise missing data. To address this issue, an aeromagnetic technology based on unmanned autonomous helicopter is proposed. Not only capable of surveying the area inaccessible vehicles vessels its high...

ABSTRACT Contourites (contour‐current deposits) are commonly associated with deep‐water environments, but this study documents a shallow‐water, muddy contourite drift in the centre of Taiwan Strait. The body (water depths 30 to 70 m, 220 km long, 50 wide, 0 m thick), its long axis approximately colinear Strait Current, is flanked on both sides by moats. Compositional data show that composed sediment carried northward Current from Choshui River draining Taiwan. coast‐normal Changyun Ridge...
To accurately characterize sound speed dispersion of shallow sediments in the Southern Yellow Sea, three types sediments, i.e., silt, clayey and silty clay, were selected to measure speeds at 25–250 kHz. Over frequency range, vary approximately from 1,536 1,565 m s−1 silt sediment, 1,511 1,527 1,456 1,466 clay sediment. The exhibits a slow increase with nearly linear gradient, but these have different characteristics. sediment relatively coarse grains has most significant dispersion, while...
