Their device stability and performance are improved greatly via ZnO capping within the device to modify the contact of the perovskite layer with the electrode, prevent reactions at the interface between the perovskite and electrode due to moisture, and completely change the conductive mechanism, thus improving the performance in all aspects. The proposed design and fabrication procedures endow the device with electro- and photo-reading functions, as well as advantages of solution and room-temperature processability for flexible devices.

In this study, we successfully developed metal-free zero-dimensional/ two-dimensional carbon nanodot (CND)-hybridized protonated g-C3N4 (pCN) (CND/pCN) heterojunction photocatalysts, synthesized via electrostatic attraction. The resulting enhancement of the photocatalytic reduction of CO2 was attributed to efficient electron migration and separation from pCN to CNDs, because of the intimate interfacial coupling of CNDs and pCN. This hindered the charge recombination process, as determined by experimental results and computational simulations.

Scanning electron microscopy (SEM) images of single-walled carbon nanotubes (SWCNTs) on substrates are produced by the combination of signals from the topography, material, and surface charge. Modulating these factors yields m- and s-SWCNTs with various appearances.

Co-vacancy-rich Co1-xS nanosheets were anchored on reduced graphene oxide (rGO) via a successive two-step hydrothermal reaction. The ultrathin nanosheets increased the quantity of cobalt vacancies (V'Co) and exposed them on the surface. Experimental results and density functional theory calculations indicated that the V'Co derived from the non-stoichiometric and sheet-like structure enhanced the oxygen evolution reaction activity of the Co1-xS/rGO hybrid.
