Journal ArticleDOI
XPS and Kelvin probe studies of SnO2/RGO nanohybrids based NO2 sensors
Bhagyashri Bhangare,Bhagyashri Bhangare,Niranjan S. Ramgir,Shweta Jagtap,A.K. Debnath,K. P. Muthe,Chiaki Terashima,Dinesh K. Aswal,Dinesh K. Aswal,Suresh W. Gosavi,Akira Fujishima +10 more
TL;DR: In this article, the authors reported the successful detection of NO2 using the hydrothermally synthesized SnO2/RGO nanohybrids, which exhibited faster response kinetics.
Journal ArticleDOI
Rapid synthesis strategy of CuO nanocubes for sensitive and selective detection of NO2
Y. H. Navale,Sachin T. Navale,Massimiliano Galluzzi,Florian J. Stadler,A.K. Debnath,Niranjan S. Ramgir,S.C. Gadkari,S.K. Gupta,Dinesh K. Aswal,V. B. Patil +9 more
TL;DR: In this article, a simple and catalyst-free thermal evaporation technique was used to synthesize copper oxide (CuO) films and their chemiresistive properties were carried out towards host of target gases.
Journal ArticleDOI
TiO2/ZnO heterostructure nanowire based NO2 sensor
Niranjan S. Ramgir,Rutuja Bhusari,N.S. Rawat,Swati J. Patil,A.K. Debnath,S. C. Gadkari,K. P. Muthe +6 more
TL;DR: In this article, a highly selective NO2 sensor based on TiO2/ZnO heterostructure nanowires (NWs) has been demonstrated successfully, where the sensor film is realised by modifying the ZnO NWs surface with Ti (~30nm) and subsequent annealing at 350 °C.
Journal ArticleDOI
Enhanced NO2 and SO2 sensor response under ambient conditions by polyol synthesized Ni doped SnO2 nanoparticles
TL;DR: In this article, Ni-doped SnO2 nanoparticles were synthesized by low temperature polyol route and systematically investigated for gas sensing applications, and they were fabricated by drop casting of the nanoparticles on gold inter-digitated electrodes and tested at room temperature (∼25°C).
Journal ArticleDOI
Role of various interfaces of CuO/ZnO random nanowire networks in H2S sensing: An impedance and Kelvin probe analysis
Niyanta Datta,Niranjan S. Ramgir,Suresh Kumar,P. Veerender,Manmeet Kaur,S. Kailasaganapathi,A.K. Debnath,Dinesh K. Aswal,S.K. Gupta +8 more
TL;DR: In this paper, the authors reported the impedance and the Kelvin probe studies of CuO/ZnO random nanowire network sensor films and showed that the contributions arising from the bulk and the nanowires-electrode contact is negligible.
