Charge transport, interfacial interactions and synergistic mechanisms in BiNbO4/MWO4 (M = Zn and Cd) heterostructures for hydrogen production: insights from a DFT+U study

Author: Opoku, F ; Govender, Krishna ; Van Sittert, GCGE ; Govender, PP Date: Oct 2017 n the 21st century, the growing demand of global energy is one of the key challenges. The photocatalytic generation of hydrogen has attracted extensive attention to discuss the increasing global demand for sustainable and clean energy. However, ... Read more
Formal comments on the Integrated Resource Plan (IRP) Update Assumptions, Base Case and Observations 2016

Author: Wright, Jarrad G ; Calitz, Joanne R ; Van Heerden, Pieter R ; Bischof-Niemz, Sebastian T ; Mushwana, Crescent ; Senatla, Mamahloko Date: Mar 2017 The CSIR determined the least cost, unconstrained electricity mix by 2050 as input into the IRP 2016. Result: It is least cost for any new investment in the power sector to be solar PV, wind or flexible power. South Africa can de-carbonise ... Read more
Understanding the mechanism of enhanced charge separation and visible light photocatalytic activity of modified wurtzite ZnO with nanoclusters of ZnS and graphene oxide: from a hybrid density functional study

Author: Opoku, F ; Govender, Krishna ; Van Sitter, CGCE ; Govender, PP Date: 2017 A first principles study of the Titania is done as used in photo-catalysis to generate charge carries. Models of titania, silica, graphene, epoxy graphene monoxide, single wall Carbon nanotubes and their respective layer were studied in order ... Read more
