  • Silica coating on nanoparticles
    Patent number: 10052604
    Abstract: This invention relates to a method for synthesizing a SiO2-coated nanoparticle, the method comprising the step of reacting a hydroxyl-functionalized silane with a nanoparticle in a substantially aqueous phase under conditions to induce silanization of the nanoparticle. The method enables silanization of the nanoparticle in aqueous phase that is substantially free of organic solvents.
    Type: Grant
    Filed: July 21, 2015
    Date of Patent: August 21, 2018
    Assignee: Agency for Science, Technology and Research
    Inventors: Thammanoon Sreethawong, Kwok Wei Shah, Shuhua Liu, Shuang-Yuan Zhang, Suo Hon Lim, Kian Seng Ang, Li Sirh Tan, Ming-Yong Han
  • Method for preparing transition metal phosphide
    Patent number: 9802821
    Abstract: There is provided a method of preparing transition metal phosphide comprising the step of mixing a solution of a transition metal precursor and a phosphorous precursor under conditions to form the transition metal phosphide. There is also provided a transition metal phosphide particle made according to the method as defined herein. There is additionally provided a method of preparing a transition metal phosphide-based electrode used for producing hydrogen in the electrolysis of water.
