A robust, inexpensive, and scalable drop-casting process was successfully developed to fabricate highly efficient and robust UV photodetectors with uniform and continuous films of ZnSnO3 and Zn2SnO4–SnO2 nanoparticles for the first time. An extreme high responsivity of ∼0.5 A W−1 at 5.0 V bias was achieved with good visible-light rejection.

As a bimetal oxide, partial zinc stannate (ZnSnO3) is one of the most promising next-generation lithium anode materials, which has the advantages of low operating voltage, large theoretical capacity (1,317 mA h g−1), and low cost. However, the shortcomings of large volume expansion and poor electrical conductivity hinder its practical application. The core-shell ZnSnO3@ nitrogen-doped carbon (ZSO@NC) nanocomposite was successfully obtained by coating ZnSnO3 with polypyrrole (PPy) through in situ polymerization under ice-bath conditions. Benefiting from this unique compact structure, the shell formed by PPy cannot only effectively alleviate the volume expansion effect of ZnSnO3 but also enhance the electrical conductivity, thus, greatly improving the lithium storage performance. ZSO@NC can deliver a reversible capacity of 967 mA h g−1 at 0.1 A g−1 after 300 cycles and 365 mA h g−1 at 2 A g−1 after 1,000 cycles. This work may provide a new avenue for the synthesis of bimetal oxide with a core–shell structure for high-performance energy storage materials.

Low-dimensional nanomaterials have been explored extensively in the last decades, partly fuelled by the new possibilities for tuning and controlling their electronic properties. In a broader perspective within catalysis, two-, one- and zero-dimensional (2D, 1D and 0D) inorganic nanomaterials represent a bridge between the selectivity of molecular catalysts and the high performance and stability of inorganic catalysts. As a consequence of the low dimensions, higher surface areas are obtained but also introduce new physics and increased tuneability of the electronic states in the nanostructured system. Herein, we derive the commonly used equations for optical transitions and carrier confinement in semiconductors and discuss their effect on the optical and photocatalytic properties of direct band and indirect band gap materials. In particular, the physical properties of the optical and photocatalytic properties of Fe 2 O 3 and ZnO will be used to exemplify the effects of the low dimensionality. Carrier confinement effects with changes in the density of states, band gap/shift of band edges will be outlined together with their effects on the tuneability of the material and their wider application as photocatalytic materials.

New high-performance photocatalytic materials are required to effectively treat water pollution. The effect of annealing temperature on the photocatalytic activities of tin dioxide (SnO2) nanoparticles is investigated in this work. SnO2 nanoparticles are prepared via a hydrothermal method and annealing at various temperatures ranging from as-prepared to 900 °C. The size of SnO2 nanoparticles increases from 4 nm to 10 nm with an increase in annealing temperature. The photocatalytic properties of these nanoparticles are evaluated through the photocatalytic degradation of methylene blue under sunlight. Photocatalytic activities decrease significantly with an increase in annealing temperature due to an increase in size and a decrease in the surface area of SnO2 nanoparticles.
