  • Electrocatalyst for water electrolysis
    Publication number: 20230227988
    Abstract: A cathode is provided for electrolysis of water wherein the cathode material comprises a multi-principal element, transition metal dichalcogenide material that has four or more chemical elements and that is a single phase, solid solution. The pristine cathode material does not contain platinum as a principal (major) component. However, a cathode comprising a transition metal dichalcogenide having platinum (Pt) nanosized islands or precipitates disposed thereon is also provided.
    Type: Application
    Filed: January 12, 2023
    Publication date: July 20, 2023
    Inventors: Viktor Balema, Sonal Padalkar, Ihor Hlova, Tian Lan, Oleksandr Dolotko, Vitalij K. Pecharsky, Duane D. Johnson, Arjun K. Pathak, Prashant Singh

  • Surfactant-Assisted Inorganic Nanoparticle Deposition on a Cellulose Nanocrystals
    Publication number: 20110262646
    Abstract: Natural biopolymers in the form of cellulose nanocrystals (CNC) are shown to have the required characteristics to serve as chemically reactive biotemplates for metallic and semiconductor nanomaterial synthesis. Silver (Ag), gold (Au), copper (Cu) and platinum (Pt), cadmium sulfide (CdS), zinc sulfide (ZnS) and lead sulfide (PbS) nanoparticles, nanoparticle chains and nanowires may be synthesized on CNCs by exposing metallic precursor salts to a cationic surfactant, cetyltrimethylammonium bromide (CTAB), and a reducing agent. The nanoparticle density and particle size may be controlled by varying the concentration of CTAB, pH of the salt solution, as well as the reduction time or reaction time between the reducing agent and the metal precursor.
