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: In some aspects and embodiments, the present application provides a wide range of porous 1-D polymeric graphitic carbon-nitride materials that are atomically doped with binary metals in different morphologies. In some embodiments, the graphitic carbon-nitride materials can be prepared with high mass production from inexpensive and natural abundant precursors. In some embodiments, the materials were used successfully for the oxidation of CO to CO2 under ambient reaction temperature in addition to the reduction of CO2 into hydrocarbons. In some embodiments, the materials can be used for practical and large-scale gas conversion for household or industrial applications.

Abstract: Set forth herein is a Fischer-Tropsch catalytic system that allows for the efficient and selective conversion of syngas to useful hydrocarbons (nC4-nC24) as well as heavy alcohols (nC1-nC9) under ambient conditions. The instantly disclosed catalytic system is more practical and scalable than other known Fischer-Tropsch catalytic systems. Also set forth herein new catalysts which comprise supported metal-oxide-based catalysts. These catalysts are useful for the conversion of syngas into liquid hydrocarbon fuels under ambient reaction conditions. The instantly disclosed catalytic system can be made in a one-pot high mass production method, which is commercially practical and scalable. A variety of reaction products can be produced by making minor adjustments to the processes disclosed herein, e.g., by adjusting catalyst composition, reaction temperature and/or reaction pressure. The instantly disclosed process(es) produce Fischer-Tropsch products, heavy hydrocarbons (e.g.
