Two-dimensional MXene@ZIF-8 hybrid-derived TiO2/TiN@N-C heterostructure as an emerging material for electrochemical sensing
Herein, facile room-temperature self-assembly and high-temperature pyrolysis strategy was successively conducted for in situ synthesizing novel TiO2/TiN@N-C heterostructure by using typical sandwich-like precursors (MXene/ZIF-8). Zero-dimensional (0D) TiO2, TiN and N-doped carbon nanoparticles were in situ formed and randomly anchored on the two-dimensional (2D) N-doped carbon substrate surface, making TiO2/TiN@N-C exhibit unique 0D/2D heterostructure. Relative to the extensively studied ZIF-8-derived N-doped carbon nanoparticles, TiO2/TiN@N-C heterostructure displayed greatly boosted electrochemical active specific surface. Benefiting from the enhanced electrochemical property of TiO2/TiN@N-C heterostructure, remarkable signal enhancement effect was achieved in terms of the oxidation of multiple hazardous substances, including clozapine, sunset yellow and benomyl. As a result, a novel electrochemical platform was constructed, the linear detection range were 10–1000 nM, 2.5–1250 nM, 10–1000 nM while the detection limits were evaluated to be 3.5 nM, 1.2 nM, 4.5 nM for clozapine, sunset yellow and benomyl, respectively. Besides, the practicability of the newly developed electrochemical method was verified by assessing the content of clozapine, sunset yellow and benomyl in real food samples.
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.
