Non-enzymatic electrochemical sensor for the reliable determination of catechol using RuS2/WO3/MWCNT ternary composite
This work focuses on the development of an innovative detection platform utilizing a novel ternary composite of transition metal dichalcogenide ruthenium disulfide (RuS2), tungsten trioxide (WO3) and multi-walled carbon nanotubes (RuS2/WO3/MWCNT) for the purpose of detecting hazardous pollutant catechol. An augmented current response for catechol was acquired by the synergetic effect of ternary composite. The unique combination of these materials enhances the sensor’s electrochemical performance due to the excellent catalytic activity of RuS2, redox properties of WO3 and the high surface area and electrical conductivity provided by MWCNTs. Morphological and structural characterizations were done using different characterization methods. The increased electroactive surface area and fast electron transfer rate resulted by the adaptation of the working electrode leads to the development of a sensitive and selective sensor. The RuS2/WO3/MWCNT modified electrode exhibited remarkable sensitivity towards catechol determination with a wide linear detection range of 1.0–1028.0 µM and a modest low detection limit of 0.61 µM. The sensor demonstrated consistent performance in assessing the reproducibility and repeatability trials. The fabricated sensor gave reliable results and satisfactory recovery range when application on real-time sample analysis.
期刊介绍：
Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
