The preparation of silicon nanotubes (SiNTs) using nanochannel Al2O3 as a template and chemical vapor deposition process is reported. outer diameters the SiNTs are around 60 nm with walls approximately 10 thick consisting crystalline amorphous silicon. A conceptual model presented (see Figure) to account for formation (right) opposed nanowires (left).
MoS2 has attracted attention as a promising hydrogen evolution reaction (HER) catalyst and supercapacitor electrode material. However, its catalytic activity capacitive performance are still hindered by aggregation poor intrinsic conductivity. Here, hollow rGO sphere-supported ultrathin nanosheet arrays (h-rGO@MoS2) constructed via dual-template approach employed bifunctional HER Because of the expanded interlayer spacing in nanosheets more exposed electroactive S–Mo–S edges, h-rGO@MoS2...
Indirectly monitoring halitosis via the detection of hydrogen sulfide (H2S) biomarkers using gas sensors is a newly emerging technique. However, such H2S are required with critically high selectivity and sensitivity, as well ppb-level limit, which remains technologically challenging. To address issues, here, we have developed highly sensitive selective NiO/WO3 nanoparticles (NPs), been synthesized by firstly hydrolyzing WO3 NPs subsequently decorating NiO in hydrothermal process....

Ammonia (NH3) sensors proposed for the simultaneous exhalation diagnosis, environmental pollution monitoring, and industrial leakage alarm require high flexibility, selectivity, stability, humidity tolerance, wide-concentration-range detection; however, technical challenges still remain. Herein, twistable water-tolerant paper-based integrated over surgical masks have been developed NH3 detection at room temperature, via decorating specially designed ternary nanocomposites (ternary-NCs) on...
Abstract With the recently‐booming hydrogen (H 2 ) economy by green H as energy carriers and newly‐emerged exhaled diagnosis human organ‐metabolized a biomarker, sensing is simultaneously required with fast response, low detection limit, tolerant stability against humidity, switching, poisoning. Here, reliable has been developed utilizing indium oxide nanocubes decorated palladium gold nanodots (Pd–Au NDs/In O 3 NCBs), which have synthesized combined hydrothermal reaction, annealing,...

Inexpensive, active, stable, and CO-tolerant nonplatinum catalysts for efficient methanol electro-oxidation are highly desirable to direct fuel cell (DMFC) technology; however, it is still challenging. In this study, we report palladium cobalt nanowires with jagged appearance (Pd–Co J-NWs), synthesized via first anodic-aluminum-oxide template-confined electrodeposition of Pd–Co regular nanowires, followed by a wet-chemical transformation. Benefiting from the "jagged" Co dopants, mass...
For hydrogen sensors built with pure Pd nanowires, the instabilities causing baseline drifting and temperature-driven sensing behavior are limiting factors when working within a wide temperature range. To enhance material stability, we have developed superlattice-structured palladium copper nanowires (PdCu NWs) random-gapped, screw-threaded spiral shapes achieved by wet-chemical approaches. The microstructure of PdCu NWs reveals novel superlattices composed lattice groups structured...
The newly emerged gas sensing detection of 3-hydroxy-2-butanone (3H-2B) biomarker is deemed as an effective avenue to indirectly monitor Listeria monocytogenes (LM). However, 3H-2B materials requiring critically high sensitivity and selectivity, ppb-level limit, remain challenging.

Meanwhile,...

We have developed "crack–tips" and "superlattice" enriched Pt–Cu nanoflakes (NFs), benefiting from the synergetic effects of "superlattice crystals"; NFs exhibit 4 times higher mass activity, 6 specific activity stability than those commercial Pt/C catalyst, respectively. Meanwhile, show more enhanced CO tolerance catalyst.
