Abstract: A novel metal-based ion-selective electrode sensor for the detection of under deposit corrosions in sour media is disclosed. The sensor can be fabricated by the sequencing electrochemical polarization followed by functionalization with an organic-inorganic layer via impregnation and polymerization. The hybrid modified multifunctional sensor allows successful selective screening and monitoring of the concertation of soluble chloride ions in sour and sweet media. The sensor is portable, durable, cost-effective, and feasible for practical commercial utilizations.

Abstract: Herein, provided are new classes of nitrogen enriched graphitic-like carbon-based materials porous nanosheets doped atomically with one or more metal atoms and/or non-metal traces, for example, binary Pt and Cu denoted as (Pt—Cu-gCN-Ns), and methods of making and using the materials, for example, in capacitive seawater desalination under ambient reaction conditions and parameters.
