Biomass-based carbon electrode materials for capacitive deionization: a review
Elisadiki, Joyce; Kibona, Talam; Machunda, Revocatus; Saleem, Muhammad; Kim, Woo-Seung; Jande, Yusufu (Springer Nature Switzerland AG., 2019-06-27)Capacitive deionization (CDI) is a promising water purification technology which works by removing salt ions or charged species from aqueous solutions. Currently, most of the research on CDI focuses on the desalination of ... -
Fish bladder-based activated carbon/Co3O4/TiO2 composite electrodes for supercapacitors
Sirengo, Keith; Jande, Yusufu; Kibona, Talam; Hilonga, Askwar; Muiva, Cosmas; King'ondu, Cecil (Elsevier B.V., 2019-06-15)Cobalt oxide/titanium dioxide/activated carbon (Co3O4/TiO2/Ac) composite was synthesized using simple sol-gel method before annealing at 300 °C. Fish bladder derived porous carbon used for the composite was synthesized by ... -
Highly porous biomass-based capacitive deionization electrodes for water defluoridation
Elisadiki, Joyce; Jande, Yusufu; Kibona, Talam; Machunda, Revocatus (Springer Nature Switzerland AG., 2019-12-09)The high concentration of fluoride (F−) in water sources is the main challenge in major fluoride belts. Though capacitive deionization (CDI) with porous carbon electrodes is the promising alternative in removing charged ... -
Hydrogen sulfide and ammonia removal from biogas using water hyacinth-derived carbon nanomaterials
Makauki, Elizabeth; King’ondu, Cecil; Kibona, Talam (Academic Journals, 2017-07-31)The presence of hydrogen sulfide (H2S) and ammonia (NH3) in biogas pose serious human health and environmental challenges. In this study, H2S and NH3 were successfully removed from biogas using water hyacinth-derived ... -
Impacts of Wood Fuel Uses on Forest Cover: The Case of Semiarid Areas in Northern Tanzania
Mahushi, Debora; Machunda, Revocatus; Kibona, Talam (University of Dar es Salaam, 2021)Satellite images for the years 1987, 1997, 2002 and 2017, and questionnaire surveys were used to assess energy sources and demands as well as the impacts of wood fuel use to forest cover changes in Meru and Mwanga ... -
Porous carbon derived from Artocarpus heterophyllus peels for capacitive deionization electrodes
Elisadiki, Joyce; Jande, Yusufu; Machunda, Revocatus; Kibona, Talam (Elsevier, 2019)Though pristine graphene exhibits remarkable mechanical and electronic properties, many electromechanical applications may come from chemically doping it with heteroatoms. The goal is to tune the atomic lattice and, in ...
