Khavharendwe Rambau

PhD Chemistry

Khavharendwe Rambau is a PhD candidate based at the HySA Infrastructure Centre of Competence,
Council for Scientific and Industrial Research. A renewable energy scientist, she obtained her
undergraduate degree in Material Science at the University of the Free State before pursuing a
Master’s degree in Physics at the University of Pretoria. She is currently doing a PhD in Physics at the
University of Pretoria. Her research is focused on using waste materials to develop porous materials
for hydrogen storage systems hosted in CSIR.

Project

Utilization of unconventional metal feedstock for MOF (Metal Organic Frameworks) synthesis used for Energy storage purposes.

Supervisor

The project focuses on developing MOF materials using waste materials are meal feedstock. The
metals are extracted from waste using leaching processes and under right synthesis conditions
coordinate with organic linkers to form MOFs.
