“…Many research has provided another methods for preparing CPEs using carbon material. Carbon paste is frequently preparing by mixing and grinding paraffin with carbonaceous material such as graphite, carbon microspheres, and multiwall carbon nanotubes powder using mortar until the paste was obtained, then packaged or pressed into a suitable electrode body (Teflon tube) [38][39][40] . The SEM images of CPEs that produced from graphite, carbon microspheres, and MWCNTs 41) can be seen in Figure 2.…”

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.

Leveraging alternating magnetic fields (AMFs) to induce localized heating in catalysts has emerged as a powerful approach to boost electrocatalytic reactions. However, the rational design and synthesis of ferromagnetic catalysts that can be stably coupled with an AMF to improve the hydrogen evolution reaction (HER) performance are still urgent and challenging. Herein, the ferromagnetic triclinic Fe5Se8 has been realized through the phase transition from nonmagnetic orthorhombic FeSe2 synergistically triggered by the selenium vacancies and the strain engineering, making it a good candidate for AMFs-assisted HER. Experimental results and theoretical calculation demonstrate that the phase transition-prepared ferromagnetic Fe5Se8 exhibits much better HER performance than nonmagnetic FeSe2. More importantly, under high-frequency AMF stimulation, the HER performance of ferromagnetic Fe5Se8 is greatly enhanced (the overpotential decreased by 63 mV), which is mainly attributed to the localized magnetic heating effect. This study realizes the controlled phase transition synthesis of ferromagnetic catalysts, indicating that AMF is an effective approach to manipulate the performance of ferromagnetic catalysts.
