摘要：

Nano lily-buds (NL-buds) garden like ZnO nanostructure synthesized by simple single step thermal decomposition method. XRD result confirmed the hexagonal (Wurtzite phase) crystal structure, and FESEM micrograph shows the formation of NL-buds like ZnO nanostructure. The chemical states and elemental composition of the elements were studied using XPS and EDS respectively. The maximum sensitivity similar to 178 was recorded for ZnO sample at 180 degrees C for 80 ppm of H-2 exposure with a fast response time of the order of similar to 1-2 s. ZnO NL-buds sensor attained a reversible, and high response towards H-2 gas signifying it as a potential candidate for H-2 sensor application. (C) 2019 Elsevier B.V. All rights reserved.
