Summary: Highly regular TiO2 nanorod array films were synthesized in situ on FTO using a simple hydrothermal method, and ZnO shell layers were grown on the nanorods to form a core-shell structure. The TiO2/ZnO nanocomposites showed enhanced ethanol sensing performances compared to TiO2 nanorods, with a low working temperature, higher sensitivity, and faster response capability. The optimum sensor based on 2c-TiO2/ZnO exhibited a significantly higher response to 50 x 10-6 C2H5OH at 340°C compared to the TiO2 sensor. The improved ethanol sensing mechanism was attributed to the unique nanorod array structure and the heterojunctions between TiO2 and ZnO.

Summary: With the development of wearable electronics, the demand for high-performance photodetectors with smaller size, lower power consumption, and higher sensitivity has increased. Photodetectors based on one-dimensional zinc oxide nanowires have been intensively investigated, but they can only detect ultraviolet light.

The effective perpendicular anisotropy energy is determined to be in the order of 10(6) erg/cm(3), and the interfacial perpendicular anisotropy energy density is estimated to be 0.32 erg/cm(2). The magnetic reversal with multi-domain feature is observed with increasing interface number.

Summary: Coupling graphene-based materials with SiC nanostructures is an effective strategy for improving photocatalytic CO2 reduction performance. In this study, vertical graphene (VG) sheets were synthesized on SiC nanowires derived from rice husks to form the VG@SiC/C composite. The resulting composite exhibited enhanced photocatalytic CO2 reduction, yielding CO and CH4 with yields of 25.5 and 2.3 μmol g-1 h-1, respectively, which is the highest CO yield among SiC-based photocatalysts. Defective VG sheets promoted sunlight absorption, CO2 adsorption and activation, electron-hole pair separation, and overall photocatalyst activity, leading to high CO2 reduction yield and selectivity.

Summary: This study successfully confines monodisperse 1T-VSe2 nanoparticles in an amorphous carbon matrix using a facile pulsed laser deposition (PLD) method combined with rapid thermal annealing (RTA) treatment. With external magnetic fields of 800 mT stimulation, these confined 1T-VSe2 nanoparticles exhibit highly efficient oxygen evolution reaction (OER) catalytic activity and remarkable durability. The experimental results demonstrate that magnetic fields can facilitate the surface charge transfer dynamics of 1T-VSe2, and modify the adsorption-free energy of *OOH, thus improving the intrinsic activity of the catalysts. This work realizes the application of ferromagnetic VSe2 electrocatalyst in highly efficient spin-dependent OER kinetics and promotes the application of transition metal chalcogenides (TMCs) in external magnetic field-assisted electrocatalysis.

Summary: Light irradiation is a promising strategy for room temperature sensing in semiconductor gas sensors, but the recombination rate of photo-generated carriers and poor visible light response of conventional sensing materials limits performance improvement. This study successfully developed a novel Z-scheme NiO/Bi2MoO6 heterostructure that showed excellent room temperature gas response towards ether under visible light irradiation. The heterostructure improved carrier separation and ether adsorption, and the visible light response of NiO/Bi2MoO6 enhanced light utilization. The in-situ construction of the heterostructure array also minimized problems associated with traditional thick film devices. This work provides important insights into the room temperature sensing performance and gas sensing mechanism of Z-scheme heterostructures.
