Summary: SnO2-ZnO composite thin films were synthesized by radio-frequency and direct-current cosputtering. The sputtering power of ZnO affected the relative content of ZnO phase and grain size in the composite film. The as-synthesized SnO2-ZnO composite films showed enhanced photoelectrocatalytic and gas-sensing performances compared to single-constituent compounds.

Summary: Environmental pollution caused by industries and human activities is a serious global challenge, while the world is also facing an energy crisis due to population growth. Designing solar-driven photocatalysts inspired by plant photosynthesis offers a fantastic solution to use solar energy for environmental pollutant removal. The use of polymeric and non-polymeric-based electrospun composite nanofibers as innovative photocatalysts not only increases photocatalytic activity, but also overcomes the limitations of traditional nanosized powder photocatalysts. These composite nanofibers have shown long-term stability, high photocatalytic efficiency, and suitability for various applications such as water treatment and antibacterial usage.

Summary: The glucose-tailored SnO2/TiO2/reduced graphene oxide ternary composite demonstrates superior photocatalytic activity due to its tailored microstructure and SnO2/TiO2 heterojunction, which enhance light absorption, charge transfer, and carrier separation. The composite can efficiently degrade organic pollutants by generating O·-2 and ·OH radicals through a redox reaction. Additionally, a possible photodegradation mechanism is proposed based on a Z-scheme transfer mode.

Summary: In this study, surfactant and organic solvents-based SnO2 rods and SnO2/rGO, SnO2/MWCNTs composite materials were successfully synthesized using microwave-assisted hydrothermal process. Electrochemical studies revealed that these materials as anode materials for lithium ion batteries showed promising initial discharge capacity and cycling stability, outperforming commercially used graphite. Additionally, the SnO2/rGO composite exhibited improved electrochemical performance due to low charge transfer resistance, enhanced electrical conductivity, and large surface area of rGO nanosheets compared to bare SnO2 rods and SnO2/MWCNTs composite.

Summary: In this paper, Eu3+ doped PAN/BaTiO3 piezoelectric composite fibers were prepared by electrostatic spinning. The addition of filler improves the piezoelectric properties of PAN, resulting in high sensitivity and dielectric constant of the fiber membrane. The prepared pressure sensor demonstrates excellent voltage and current output. These results suggest that Eu3+ doped PAN/BaTiO3 piezoelectric composite fiber membranes have great potential in flexible pressure sensors, wearable self-powered devices, and optoelectronic devices.
