Polyaniline/Carbon Nanotube‐Modified Carbon Felt for Accelerating Underwater Microbial Gas Production to Enhance Power Generation
Source abstract
Abstract
Abstract Harvesting energy from bubbles produced by seafloor microorganisms to power underwater devices is a promising method. However, the slow gas production rate under natural conditions hinders the practical application of this technology. Herein, we synthesized polyaniline/carboxyl multiwalled carbon nanotube/carbon felt (PANI/c‐MWCNT/CF) by dip‐coating and in‐situ chemical polymerization for accelerating gas production rate from underwater anaerobic digestion. The optimal WNCNTS addition dosage in modified CF was determined to be 0.5 g/L. Compared with the control group, the PANI/c‐MWCNT/CF improved the gas production yield and rate by 48% and 59%, respectively. Furthermore, after seven days of continuous experiments, the high gas production rate was maintained, demonstrating that the PANI/c‐MWCNT/CF is durable and stable. This study supplies enough gas for the underwater bubble energy harvester, removing environmental constraints on subsea in‐situ power generation and opening up a broad prospect for the power supply to underwater equipment.
