Improved C₂H₂sensing properties of Ni doped ZnO nanorods

A self-powered photoactive room temperature gas sensor based on a porphyrin-functionalized ZnO nanorod/p-Si heterostructure

“…14 Furthermore, no additional peaks were obtained for any secondary phase of ZnO or silicon substrate, indicating the high purity of the synthesized ZnO NRs. 15 The crystallite size was calculated using the Scherrer formula as 56.62 nm. The structural and morphological analysis of the porphyrin-coated ZnO NRs was carried out using HR-SEM.…”

Synthesis of Ni–Ag–ZnO solid solution nanoparticles for photoreduction and antimicrobial applications

“…2(b) ). 30 The disappearance of diffraction peaks at higher angles is due to the lattice strain. 31 In Ag–ZnO solid solution NPs (1 : 1 molar ratio), the diffraction peaks (111), (200), (220), (311) located at 37.66°, 43.9°, 64.2°, and 77.5° belongs to the face-centred cubic (fcc) structure of silver (JCPDF 00-001-1164).…”

Mesoporous SnO2 Nanowires: Synthesis and Ethanol Sensing Properties

“…Due to the compact size, easy production, low cost, and simple measuring electronics, metal oxide gas sensors have been extensively exploited to detect volatile organic compounds [1][2][3][4][5]. A large number of investigations have shown that tin oxide (SnO 2 ) with large excitation energy, excellent electronic and photonic properties, is one of the most excellent sensing materials [6,7].…”
