4results about How to "Guaranteed dispersion" patented technology

This invention belongs to the field of catalyst materials technology, specifically relating to a Pd-UiO-66 particle electrode, its preparation method, and its application. The Pd-UiO-66 particle electrode uses a zirconium-based metal-organic framework UiO66 as a support. Palladium nanoparticles are obtained by reducing palladium salts with sodium borohydride. The palladium nanoparticles are then reacted with the hydroxyl groups on the polyvinyl alcohol molecules. 2+ The coordination between the components and the steric hindrance effect of the long-chain molecules of polyvinyl alcohol regulate the dispersion of palladium nanoparticles, allowing palladium nanoparticles to be loaded onto UiO66 to obtain Pd-UiO-66. The Pd-UiO-66 particle cathode in this invention avoids the aggregation of palladium nanoparticles, greatly increasing the electrode area / solution volume ratio and helping to provide more active sites for dechlorination.

The application discloses an on-chip optical amplifier and a preparation method thereof. The on-chip optical amplifier comprises an optical waveguide, an optical isolation layer, a substrate and an ion-doped layer, wherein the ion-doped layer comprises a doped layer medium and doped ions, the optical isolation layer is located between the substrate and the ion-doped layer; the ion-doped layer is tightly covered outside the optical waveguide, or is located between the optical waveguide and the optical isolation layer and is tightly attached to the optical waveguide. Compared with a conventional optical amplification mode using an erbium-doped optical fiber amplifier, an ion-doped waveguide and the like, the application can realize an integrated and chipped optical amplifier, has the characteristics of CMOS compatibility, and can realize optical-matter interaction without doping the optical waveguide device, eliminates the problem of introducing a crystal structure defect of the optical waveguide caused by direct ion doping, and guarantees optical index parameters such as dispersion and loss of the integrated photonic device.
