Journal ArticleDOI
Room temperature ferromagnetism and gas sensing in ZnO nanostructures: Influence of intrinsic defects and Mn, Co, Cu doping
Gugu H. Mhlongo,Katekani Shingange,Zamaswazi P. Tshabalala,Baban P. Dhonge,F. A. Mahmoud,Bonex W. Mwakikunga,David E. Motaung +6 more
TL;DR: In this paper, a combination of defect structure analysis based on photoluminescence (PL) and electron paramagnetic resonance (EPR) was employed to detect coexisting oxygen vacancies (V O ) and zinc interstitials (Zn i ) defects in undoped and transition metal doped ZnO systems.
Journal ArticleDOI
Highly selective NH3 gas sensor based on Au loaded ZnO nanostructures prepared using microwave-assisted method.
Katekani Shingange,Zamaswazi P. Tshabalala,Odireleng M. Ntwaeaborwa,David E. Motaung,Gugu H. Mhlongo +4 more
TL;DR: It was confirmed that Au form nanoparticles loaded on the surface of ZnO, and it was demonstrated that Au/ZnO based sensors were highly selective to NH3 gas at room temperature.
Journal ArticleDOI

TL;DR: In this paper, the effect of annealing temperature on the sensitivity and selectivity of TiO 2-based sensors for detection of CH 4 gas at room temperature was investigated for underground mining environment.
Journal ArticleDOI
0D to 3D ZnO nanostructures and their luminescence, magnetic and sensing properties: Influence of pH and annealing
Katekani Shingange,Katekani Shingange,Zamaswazi P. Tshabalala,Zamaswazi P. Tshabalala,Baban P. Dhonge,Odireleng M. Ntwaeaborwa,David E. Motaung,Gugu H. Mhlongo +7 more
TL;DR: In this article, a successful synthesis of ZnO nanostructures with different particle morphologies using the microwave-assisted hydrothermal method was reported, where the effect of varying the pH before and after annealing at 450°C on the particle morphology was evaluated.
Journal ArticleDOI
Ultra-sensitive and selective NH3 room temperature gas sensing induced by manganese-doped titanium dioxide nanoparticles
Zamaswazi P. Tshabalala,Katekani Shingange,Franscious Cummings,Odireleng M. Ntwaeaborwa,Gugu H. Mhlongo,Gugu H. Mhlongo,David E. Motaung,David E. Motaung +7 more
TL;DR: Gas sensing studies showed that Mn2+ doped on the TiO2 surface improved the NH3 sensing performance in terms of response, sensitivity and selectivity and the sensing mechanism towards NH3 gas is proposed.
