“…However, it is worth mentioning that all these remain speculations until now. It is noteworthy to mention that other semiconducting metal oxides, such as ZnO and CeO 2 , did not show these temperature fluctuations. − These ferrites materials are ceramics with order of resistance ∼10 7 Ω. The temperature fluctuations did not even show on other tested gases except LPG.…”

“…Gas sensing mechanism.-The Fabrication of Sensor is discussed in one of our previous paper. 45 With reference to our above studies we proposed a plausible gas sensing mechanism based on adsorption-desorption mechanism. Oxygen molecules are adsorbed on the ZnO: SnO: Pd (ZSP) nanocomposite surface through two mechanisms: Physisorption and Chemisorption.…”

“…Noble metals exhibit electrostatic properties because of its collective oscillations of charge density with optical frequencies, known as surface plasmons which have attracted considerable attention for potential applications in photonic devices, medical imaging, diagnostics, therapeutics, etc. 12,[41][42][43][44][45][46] In the present study, p-n type ZnO: SnO nanocomposite was indigenously synthesized and used as suitable material for development of H 2 gas sensor. The effective charge transfer process in the interfaces of ZnO: SnO nanocomposite and the effect of noble metal (Pd) addition on the gas sensing characteristics towards H 2 gas and other interfering gases were studied.…”

In the present study we report the design & synthesis of a novel p-n type semiconducting Pd incorporated ZnO: SnO (ZSP) nanocomposite as Hydrogen (H 2 ) gas sensor, which demonstrates an efficient conductivity and superior stability through nanostructured engineering. The structural characteristics were investigated by X-ray diffraction (XRD), Particle Size Analyzer (PSA), X-ray Photoelectron Spectroscopy (XPS) and morphology by High Resolution Transmission electron microscopy (HRTEM). Gas sensing characteristics of ZnO: SnO nanocomposite towards 500 ppm hydrogen gas exhibited Sensitivity of S = 0.6 whereas ZnO: SnO: Pd nanocomposite exhibited higher Sensitivity of S = 0.91 at a lower operating temperature of 150 °C. The achieved features make the sample ZSP a potential candidate for development of highly Sensitive and Selective H 2 gas sensor.

“…Secara khusus, propana telah menarik perhatian sebagai bahan sumber H 2 yang potensial karena mudah diangkut. Selain itu, infrastruktur gas yang tersedia dapat digunakan untuk memperoleh propana sebagai gas cair [5]. Dengan menggunakan teknik steam reforming, 1 mol propana dapat dikonversi secara efisien menjadi 4 mol H 2 .…”

Steam reforming is a method for producing hydrogen gas as a solution for renewable energy generation. One source of hydrogen in a steam reformer is propane gas. The advantage of propane gas is the ease of transportation and storage. The production of hydrogen gas in a steam reformer is certainly influenced by supporting factors such as the temperature of the reformer. In this study, propane steam reforming was simulated in 3D with COMSOL Multiphysics 5.3ª software with bed reformer temperatures varying from 600, 650, 700, 700, 750, 800 and 850 o C with steam to carbon (S/C) ratio 3. The results show that increasing the temperature causes the density of the reformer to decrease, which in turn results in increased gas velocity. In addition, an increase in temperature in the bed reformer increases propane conversion to 87.8% and produces about 40% hydrogen at 850 o C.
