"Novel bi-and tri-metal borohydrides for hydrogen storage"

SeyedHosein Payandeh Gharibdoust / Early Stage Researcher at Aarhus University, Denmark

Working title of thesis

Novel complex metal hydrides for efficient and compact storage of renewable energy as hydrogen and electricity.

Objectives

  • Synthesis of novel bi- and tri-metal borohydrides for hydrogen storage
  • Determination of thermodynamic and kinetic properties
  • Structural characterization
  • Evaluation of potentials for industrial application

Tasks and methodoloy

In this project selected novel bi- or tri-metal borohydrides will be prepared by wet chemistry, mechano-chemical methods, annealing or their combinations. Solvent and halide free products will be produced. In addition, their structure and mechanisms of release and uptake of hydrogen and explore additives for enhancing reaction kinetics will be studied with the aim to tailor both decomposition temperature and mechanisms for release and uptake of hydrogen.

Short CV

Education & Qualifications

PhD of Chemistry 2014-2017
Aarhus University

  • Thesis: “Preparation and characterization of Novel bi- or tri- metal borohydrides, for hydrogen storage and solid electrolytes in batteries by using wet chemistry, mechanochemical methods, annealing or combinations”
  • Advisor: Associate professor Torben Jensen, Assistant professor Dorthe Ravnsbæk

Ongoing Projects and results:

  • Synthesizing pure rare earth metal borohydrides
    A new method based on wet chemistry is established to prepare pure rare earth metal borohydrides.
  • Synthesizing bimetallic compounds for Hydrogen and electrochemical energy storage
    New synthesis methods using either metathesis or addition reactions developed for bimetallic rare earth metal borohydrides, which are potential Li, Na or Mg ion conductors and simultaneously store significant amounts of hydrogen
