STUDENT DETAILS
Xoliswa Lindokuhle Dyosiba
Miss Xoliswa Lindokuhle Dyosiba is a PhD candidate working under the supervision of Dr. Jianwei
Ren and Prof. Maurice Onyango. She joined HySA Infrastructure at the CSIR in June 2016 and is
currently studying the use of Waste Polyethylene Terephthalate (PET) as sustainable precursors
for large scale Metal-organic Frameworks (MOFs) synthesis for hydrogen storage application.
She completed Her BTech at the Tshwane University of Technology in 2009 where she
researched the adsorption of fluoride in drinking water with thermo–chemically treated
limestone and activated alumina as adsorbents. Having completed her BTech in 2010 Miss
Dyosiba then pursued an MTech in Chemical Engineering where she undertook to research the
adsorption of Chromium(VI) from wastewater using Polypyrrole/ AL 2 O 3 : Fixed bed column
operation studies. This project involved the application of nanotechnology in the purification of
industrial wastewaters contaminated by heavy metals. The research focus was specifically on the
development and synthesis of a novel nanosorbent via in situ chemical oxidative polymerization
for enhanced removal of highly toxic Cr(VI) from wastewater. She then received her MTech from
the Tshwane University of Technology (TUT) Cum Laude in 2015.

Project
Supervisor
Crystalline MOFs are promising as hydrogen storage materials due to their controllable porous
structure and higher specific surface areas. Benzene dicarboxylate (BDC) based MOFs, particularly,
have been explored as one of the most important prototype MOFs for hydrogen storage applications
because of their exceptional properties. However, one of the challenges currently precluding the
industrial application of BDC based MOFs is a lack of cheap and green/environmentally friendly
methods for their synthesis. This study focuses on the preparation of BDC based MOFs with a direct
use of waste PET as a source of BDC in hydrothermal/solvothermal reactions for hydrogen storage
applications.
