Rationale
With the continuous renewal of new psychoactive substances (NPS), the abuse of NPS has seriously harmed social security and public safety. The number of deaths from the abuse of NPS is increasing year by year. Therefore, there is an immediate need to develop an effective method for detecting NPS.
Methods
Direct analysis in real‐time tandem mass spectrometry (DART‐MS/MS) was used to detect...
A highly efficient g‐C3N4 photocatalyst is developed by a novel one‐pot thermal polymerization method under a salt fog environment generated by heating the aqueous solution of urea and mixed metal salts of NaCl/KCl, namely SF‐CN. Thanks to the synergistic effect of the oxygenation and chemical etching of the salt fog, the obtained SF‐CN is an oxygenated ultrathin porous carbon nitride with an intermolecular...
