标题：Environmental chemistry 2020 -Anthraquinone and L-amino Acid Derivatives Schiff Base Cu(II) Complexes as a Mediator between Cathode of Biofuel Cell and Oxygen-reducing Laccase- Yuto Takeuchi- Tokyo University of Science
摘要：Cathode materials of biofuel cells sometimes contain mediator(metal complexes) to enhance electron transfer efficiencybetween electrode and laccase. Laccase is an enzyme whichcatalyzes four-electron reduction of oxygen to water. Chemicalsof the highest commercial grade available (solvents from KantoChemical, organic compounds from Tokyo Chemical Industryand metal sources and MWCNT from Wako) were used asreceived without further purification. Laccase from Trametesversicolor was purchased from Sigma-Aldrich (St. Louis, MOUSA). Basically, 2-hydroxy-9,10-dioxo-9,10-dihydroanthracene-1-carbaldehyde was prepared as per the literature method(formylation) with modification of using a Biotage Initiator+microwave synthesis device in trifluoroacetic acid at 403 K for90 min. Treatment of 2-hydroxy-9,10-dioxo-9,10-dihydroanthracene- 1-carbaldehyde (0.10 g, 0.40 mmol) andNaHCO3(0.034 g, 0.40 mmol), and L-alanine (0.036 g, 0.40mmol).
