We report a novel anode electrocatalyst for microbial fuel cells (MFCs). Mesoporous tungsten trioxide (m-WO 3 ) was synthesized from mesoporous silica template and mixed with carbon nanotubes (CNTs), resulting in electrocatalyst CNTs/m-WO 3 . The introduction of CNTs not only enhances the electronic conductivity but also yields a delocalization of m-WO 3 , which enhances the conjugated interaction of CNTs with m-WO 3 . Electrochemical measurements indicate that the resulting CNTs/m-WO 3 exhibits excellent electrocatalytic activities, enabling the MFC based on Escherichia Coli with a maximum power density of 1.11 ± 0.022 W m −2 , which is strikingly higher than the MFC using m-WO 3 anode (0.76 ± 0.017 W m −2 ), and comparable to that using platinum anode (1.26 ± 0.025 W m −2 ). The proposed conjugated structure strategy provides an inspiration in designing new electrocatalysts for improving ...

碳纳米管共轭中孔三氧化钨作为微生物燃料电池的阳极电催化剂

我们报告了微生物燃料电池（MFCs）的新型阳极电催化剂。由介孔二氧化硅模板合成介孔三氧化钨（m-WO 3），并与碳纳米管（CNTs）混合，得到电催化剂CNTs / m-WO 3。CNT的引入不仅增强了电导率，而且产生了m-WO 3的离域，这增强了CNT与m-WO 3的共轭相互作用。电化学测量表明，所得的CNTs / m-WO 3具有出色的电催化活性，使基于埃希氏大肠杆菌的MFC的最大功率密度为1.11±0.022 W m -2，比使用m-WO 3的MFC高得多。阳极（0.76±0.017 W m -2），并且与使用铂阳极（1.26±0.025 W m -2）相当。
