Codoping-Induced, Rhombus-Shaped Co3O4Nanosheets as an Active Electrode Material for Oxygen Evolution

Abstract: Nanostructured Co3O4 doped with Zn(2+), Ni(2+), and both were directly grown on an ITO substrate by an easily available hydrothermal method. The doped Co3O4 showed a unique structural morphology evolution upon controlling the doping elements and the doping ratio of the cations. For the codoped s les, the novel rhombus-shaped Co3O4 nanosheets doped with Zn(2+) and Ni(2+) (concentration ratio of 1:2) exhibited the optimal electrocatalytic performance. The s le showed a current density of 165 mA cm(-2) at 1.75 V, approximately 1.6 and 4 times higher than that of s les doped with Zn(2+) and Ni(2+) at a concentration ratio of 1:1 and 1:3. The unique architecture and its corresponding modified physical properties, such as high active-site density created by codoping, large structural porosity, and high roughness, are together responsible to its superior performance. For codoped Co3O4 nanostructures, Zn(2+) facilitates the creation of Co cations in their high oxidation state as active centers, while Ni(2+) contributed to the new active sites with lower activation energy. The synergistic effect of Zn(2+) and Ni(2+) doping can explain the improved physicochemical properties of codoped Co3O4 nanostructures.

Aggregation-Induced Emission Luminogens as Color Converters for Visible-Light Communication
Publisher: American Chemical Society (ACS)
Date: 11-09-2018
Abstract: In this work, we report the application of the aggregation-induced emission luminogens (AIEgens) as color converters for visible light communication (VLC). In the form of pure solid powder, the AIEgens studied herein have demonstrated blue-to-red full-color emissions, large -6 dB electrical modulation bandwidths up to 279 MHz (∼56× that of commercial phosphor), and most of them can achieve high data rates of 428-493 Mbps (up to ∼49× that of commercial phosphor) at a maximum bit error rate of 3.8 × 10
