Synthesis and characterization of micro- and mesoporous materials for low temperature selective catalytic reduction of nitrogen oxides
(University of the Western Cape, 2011)In summary, it has been shown during this study that bimetallic Fe and Mn containing catalysts can be prepared by wet impregnation and not by ion exchange because of the competition between two different metals at different ... -
The synthesis and characterization of mixed-organic-cations tin halide perovskites for enhanced photovoltaic cell application
(University of the Western Cape, 2018)In this research, novel hybrid perovskite materials were synthesized, characterized and applied in photovoltaic cells (PVCs) to enhance the performance of PVCs. Mixed-organic-cations tin halide perovskites (MOCTPs) were ... -
Synthesis and characterization of nanofluids for cooling applications
(University of the Western Cape, 2006)Low thermal conductivity is a primary limitation in the development of energy-efficient heat transfer fluids that are required in numerous industrial sectors. Recently submicron and high aspect ratio particles (nanoparticles ... -
Synthesis and characterization of new adsorbents for CO2 capturing
(University of the Western Cape, 2014)Carbon dioxide emissions have become a major concern as they are one of the contributing factors to the “green-house” effect. Recently, much effort has been put into separating carbon dioxide (CO2) from flue gases linked ... -
Synthesis and characterization of pt-sn/c cathode catalysts via polyol reduction method for use in direct methanol fuel cell
(2013)Direct methanol fuel cells (DMFCs) are attractive power sources as they offer high conversion efficiencies with low or no pollution. One of the major advantages DMFCs has over PEMFCs is that methanol is a liquid and can ... -
