Cathode catalysts are vital components in microbial fuel cells (MFCs) for power generation. However, the high cost of platinum (Pt), the preferred catalyst material, limits its scalability. Several efforts have been made to improve the catalytic performance of MFCs in order to replace the existing catalysts. Graphene exhibits excellent catalytic activity due to its unique physicochemical properties. However, conventional graphene fabrication methods are complex and expensive. In contrast, laser-induced graphene (LIG) offers a single-step, cost-effective approach with high conductivity and catalytic activity. This study investigates the performance of LIG derived from poly(ether sulfone) (PES)-modified carbon cloth (CC) as a cathode catalyst for wastewater treatment in MFCs. X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDS), and Raman spectroscopy were used to characterize the prepared catalyst, demonstrating its unique nature and purity. Additionally, cyclic voltammetry (CV) and electron impedance spectroscopy (EIS) analysis evaluate the PES-LIG-CC's charge-transfer capacity and electrocatalytic activity. MFC with PES-LIG-CC has given a potential value (0.740 V) that was 2.1 times higher than bare CC (0.360 V) but lesser than Pt/C catalyst (1.050 V). The PES-LIG-CC cathode achieves a maximum chemical oxygen demand (COD) removal of 84% after three cycles. The finding suggests that the PES-LIG-CC catalyst for power output offers an affordable substitute for the expensive Pt/C catalysts used in MFC for wastewater treatment.

“…It was reported that the optimum potential of H 2 oxidation based on ionic liquid was about 0.4 V [15,16]. Nevertheless, the sensor also had good performances when the potential of the work electrode with platinum black as catalyst was 0 V (vs. Pt reference electrode) [20]. To decrease initial stabilization time, the commercial electrochemical gas sensors generally used 0 V bias potential [21].…”

Hydrogen fuel cell ship is an important way to realize green shipping, and the safety of hydrogen fuel ship is primary issue that shall be concerned. H2 gas sensors can provide online monitoring of H2 concentration and it is an effective mean to insure safety of hydrogen fuel. In this study, an amperometric electrochemical H2 gas sensor based on room-temperature ionic liquid was developed, which was expected to be applicable to monitoring of H2 concentration in the hydrogen fuel cell ship. A threeelectrode H2 gas sensor was fabricated by using room-temperature ionic liquid N, N, N-trimethyl-Nbutanesulfonic acid ammonium hydrogen sulfate ([TMBSA][HSO4]) as electrolyte and using platinum black as catalyst. The H2 gas sensor not only had the advantages of the conventional aqueous electrolyte sensor, such as high sensitivity, fast response, and the linear relationship between the response current and the concentration of H2, but also overcame the problem that the conventional electrochemical gas sensor cannot be applied to high humidity environment. After storage in high-humidity environment (98% RH) for three weeks, the sensor had stable performances, with current signal drift less than 2.25%. The sensor has a good potential application prospect in ships with high temperature and humidity environment.

“…Various sensing platforms have been employed for H 2 detection until now, such as resistance-, mixed-potential-, and fuel cell-based sensors. − However, both the resistance- and mixed-potential-type gas sensors need to operate at elevated temperatures to reduce device resistance and to obtain sufficient ion transport capacity for the solid electrolyte, respectively. This in fact poses a safety hazard in the detection of unknown concentrations of H 2 .…”

A phosphorus-doped carbon nanotube (CNT) aerogel as the support material was loaded with Pt nanoparticles in fuel cell-type gas sensors for ultrasensitive H 2 detection. The high surface area of the CNT scaffold is favorable to providing abundant active sites, and the high electrical conductivity facilitates the transport of carriers generated by electrochemical reactions. In addition, the CNT aerogel was doped with phosphorus (P) to further enhance the conductivity and electrochemical catalytic activity. As a result, the fuel cell-type gas sensor using the Pt/CNT aerogel doped with the optimal P content as the sensing material shows considerable performance for H 2 detection at room temperature. The sensor exhibits an ultrahigh response of −921.9 μA to 15,000 ppm of H 2 . The sensitivity is −0.063 μA/ppm, which is 21 times higher than that of the conventional Pt/CF counterpart. The sensor also exhibits excellent repeatability and humidity resistance, as well as fast response/recovery; the response/recovery times are 31 and 4 s to 3000 ppm of H 2 , respectively. The modulation of the structure and catalytic properties of the support material is responsible for the improvement of the sensor performance, thus providing a feasible solution for optimizing the performance of fuel cell-type gas sensors.
