Article Abstract
In this work, Ni(OH) nanocages@MnO nanosheets core-shell architecture (Ni(OH) NCs@MnO NSs CSA) was successfully prepared through coordinated etching and precipitation (CEP) route followed by hydrothermal reaction, and then tested as sensitive electrode material for detection of dopamine (DA). The three dimensional (3D) hollow Ni(OH) core effectively prevented the aggregation of MnO NSs, leading to high utilization rate of MnO NSs. Meanwhile, the two dimensional (2D) MnO shell endowed Ni(OH) NCs with larger specific area and abundant diffusion channels, facilitating mass transport. Ni(OH) NCs@MnO NSs CSA modified glassy carbon electrode (GCE) exhibited two satisfying sensitivities of 467.1 and 1249.9 μA mM cm within the two linear ranges of 0.02-16.30 μM and 18.30-118.58 μM, respectively. Furthermore, Ni(OH) NCs@MnO NSs CSA/GCE presented low detection limit of 1.75 nM and short response time of 1.14 s. Overall, Ni(OH) NCs@MnO NSs/GCE looks promising for analytical sensing of DA thanks to its prominent electrocatalytic dynamic issued from the 3D hollow structure@2D nanosheets core-shell architecture.

Organic nucleophile-assisted natural seawater electrolysis has emerged as a promising strategy for green hydrogen production by significantly reducing energy consumption. Among Ni-based electrocatalysts, NiMoO has drawn attention for its activity in both oxygen evolution reaction (OER) and urea oxidation reaction (UOR). However, its practical application is hindered by severe surface passivation, particularly at industrial current densities (e.

Electronic capacitor films based on polymer matrices and inorganic nanofillers capable of storing more energy play a crucial role in advanced modern electrical industries and devices. Herein, a series of nanocomposite films composed of "core-shell-dot" BNNs-PDA@Ag hybrid structures with multiple breakdown strength enhancement mechanisms as fillers and methyl methacrylate--glycidyl methacrylate (MG) copolymers as matrices were successfully synthesized. The introduced 2D and wide-bandgap BNNs not only enhanced the breakdown strength by taking advantage of their excellent physical properties, but also further improved their energy storage properties both at ambient and elevated temperatures through the formation of deeper traps at the organic-inorganic interface.

Photocatalytic CO reduction offers a dual solution to mitigate the energy crisis and reduce carbon emissions. In situ synthesis of the CuWS@SnInS (CWS@SIS) composite has established S-S bonds at the interface, which act as atomic-scale interfacial "bridges" to stabilize the heterojunction interface. SnInS nanosheets are uniformly dispersed on the CuWS surface, activating the (101) crystal plane of CuWS to consume photogenerated holes.
