Carbon paste electrodes (CPEs) are a type of electrochemical sensor that have been widely used for sensing and monitoring various analytes. Recently, there has been a growing interest in incorporating nanomaterials into CPEs to improve their performance and sensitivity.Here are some recent trends and applications of modified CPEs based on nanomaterials, which have been shown to have enhanced sensitivity and selectivity for the detection of various analytes such as those in food and drug samples. The high surface area and electrical conductivity of CPEs make them ideal for use in electrochemical sensing applications. Nanomaterial-based CPEs have also been widely studied for their high sensitivity and selectivity in sensing various analytes. Nanomaterials such as Multi-Walled Carbon Nanotube (MWCNT), Single-Walled carbon Nanotube (SWNCT), Graphene, or other naomaterial have excellent electrical conductivity, large surface area, and high mechanical strength, making it an attractive nanomaterial for use in CPEs. A CPEs-based nanomaterial has been used in electrochemical detection, demonstrating improved sensitivity compared to traditional CPEs. In general, the incorporation of nanomaterials into CPEs has opened up new opportunities for the development of highly sensitive and selective electrochemical sensors for a wide range of applications including environmental monitoring, drug diagnosis, and food safety.

“…The bimetallic sulfides undoubtedly emerge as the most promising catalysts due to the synergistic effects among diverse metal atoms and their potential for an increased number of active sites, [15] as compared to monometallic sulfides, they often exhibit superior catalytic activity towards many chemical transformations. Bimetallic sulfides have been found extensive applications in various fields, including supercapacitors, [16] hydrogenation catalysts, [17] dye‐sensitized solar cells [18] and lithium‐ion batteries, [19] however, they are rarely used as sensing materials for H 2 O 2 . In addition, without any template precursors, the simple and rapid synthesis of bimetallic sulfides with a narrow particle size distribution remains a challenge [20,21] …”

The sensitive and reliable nanozyme‐based sensor enables the detection of low concentrations of H2O2 in biological microenvironments, it has potential applications as an in‐situ monitoring platform for cellular H2O2 release. The uniformly dispersed bimetallic sulfide (Zn2SnS4) nanoflowers were synthesized via a one‐pot hydrothermal method and the two kinds of metal ions can serve as morphology and structure directing agents for each other in the synthetic process. The nanoparticles were utilized as nanozyme materials to fabricate a novel electrochemical sensor, and it exhibits a distinct electrochemical response towards H2O2 with excellent stability and detection capability (with a minimum detection limit of 1.79 nM (S/N = 3)), the excellent characteristics facilitate the precise detection of low concentrations of H2O2 in biological microenvironments. Use the macrophages differentiated from leukemia THP‐1 cells as a representative sensing model, the sensor was successfully utilized for real‐time monitoring of the release of H2O2 induced by living cells, which has significant potential applications in clinical diagnosis and cancer treatment.

“…The slurry bed residue hydrogenation process is an alternative process for heavy oil hydrogenation, and the dispersed catalyst is used to solve the problems effectively such as the diffusion limitation in the pore of the traditionally supported catalyst and the deactivation of the catalyst caused by coke blockage 7, 8 . Generally, metal sulfi des formed in the process of hydrocracking are the main catalytic active species, and metal sulfi de catalysts are prepared by in situ prevulcanization of metal precursors in the feed 9 . The precursors of catalysts are classifi ed into water-soluble and oil-soluble precursors.…”

Coal liquefaction and heavy oil processing have become the urgent need for national energy strategic technology reserves in China. However, the inactivation of solid catalysts in these processes is an inevitable problem. Therefore, a self-catalysed method was proposed. The properties of raw oil could be changed by adding a modifier, as it has the function of self-catalysis, and the additional catalyst is no longer needed. The effect of 200 ppm modifier on the hydrogenation of heavy oil and 500 ppm on the hydrogenation of coal and oil were investigated. The results showed that modifiers could be miscible with heavy oil at 50~100 °C and could change the properties of oil. When the temperature exceeded 250 °C, the sulfur element in the heavy oil combined with the metal element brought in by the modifier to form a particle with the size of 2–8 nm, which could interact with the hydrogen molecule to activate the hydrogen molecule. Activated hydrogen atoms further formed the complexes with nickel, vanadium, calcium, iron, and other elements in heavy oil to achieve the purpose of purifying and lightening the oil phase. Therefore, the self-catalysed method could be widely used in oil refining and would greatly promote the development of the oil refining and catalysis industry.
