Synthesis of porous ZnO nanostructures using bamboo fibers as templates

Abstract

In this study, we fabricated ZnO nanostructures using bamboo fibers as templates. The starting material used was zinc acetate, and the nanostructures were synthesized by soaking and calcining the bamboo fibers. The fabricated nanostructures were characterized using X-ray powder diffraction (XRD) analysis, scanning electron microscopy (SEM), and ultravioletvisible spectrophotometry. The results showed that the size of the ZnO nanoparticles was approximately 20 -100 nm. When the ZnO nanoparticles were used as the catalyst in the photodegradation of methyl orange, the dye degraded by 95.98 % in 80 min. The response and recovery times of a gas sensor based on the ZnO nanoparticles were 25 and 24 s, respectively, during the detection of C 2 H 5 OH in a concentration of 10 ppm at 270°C.

Development of ZnO Nanoflake Type Structures Using Silk Fibres as Template for Water Pollutants Remediation

“…[1]. They possess a large direct band gap of~3.37 eV, and are used as functional devices in solar cells, and photocatalysts in remedial applications and sensor materials [2]. ZnO has vast areas of application, and a variety of nanostructures including nanoparticles, nanowires, nanorods, nanotubes, nanobelts, and other complex morphologies have been fabricated and reported [3].…”

“…Template directed synthesis of ZnO materials is gaining significant interest in research communities, and various porous and non-porous materials of ZnO have been synthesized [2,5]. Polyethylene glycol, copolymer gels, polyvinylpyrrolidone, nanofibres, etc., templates have been used to produce porous materials, while various soft biological materials, like butterfly wings, bacteria, bamboo, cotton, wool, silk fibers, etc., have been used to produce ZnO networks and hybrid materials [2,11,12]. The selection of natural and renewable sources to synthesize nanomaterials is imperative to sustainable development, and can limit hazardous wastes.…”

A Novel Vible-Light Photodetector Based on Chlorophyll-Modified ZnO Nanoparticles

“…Based on the peaks in the diffraction pattern, a hexagonal wurtzite structure of ZnO can easily be indicated according to JCPDS No. 36-145 [10]. The entire peak of ZnO appears in the diffraction pattern as extending from the angle of 2=30−70, consecutive to the reflection planes of (1 0 0), (0 0 2), (1 0 1), (1 0 2), (1 1 0), (1 0 3), (2 0 0), (1 1 2), and (2 0 1).…”
