TL;DR: Three-dimensional cone-shaped hierarchical SnO2 nanostructures display the highest relative response up to about 175 toward 100 ppm of acetone as an example and exhibit good sensing responses toward other typical volatile organic compounds (VOCs).

TL;DR: In this article, a review of the recent advances of representative electrochemical spectral methods and their applications is presented, including electrochemical atomic absorption spectrometry (EC-AAS), electrochemical total reflection X-ray fluorescence, and electrochemical laser-induced breakdown spectroscopy (ECLIBS).

TL;DR: This approach of uniformly distributing the small-sized defective nanoparticles on the electrode surface provides a new opportunity for modifying the electrodes, as well as the realization of their applications in the field of environmental electroanalysis for heavy metal ions.

TL;DR: In this article, an electrochemical sensor based on Ag nanoparticles anchored onto CuO porous nanobelts (Ag/CuO PNBs) was constructed for the ultrasensitive determination of dopamine (DA), which was prepared via a facile two-step cation-exchange reaction followed by in-situ thermal conversion.

TL;DR: Combining X-ray absorption spectroscopy, density functional theory calculation and reaction kinetics simulation, it is demonstrated that Co single atoms stabilized in N2C2 support serve as active sites to catalyse H3AsO3 reduction via the formation of Co-O hybridization bond, leading to a lower energy barrier, promoting the breakage of As-O bonds.
