Kev coj tus cwj pwm bioelectrochemical ntawm peb triphenylmethane (TPM) dyes feem ntau siv los ua pH ntsuas, thiab lawv daim ntawv thov hauv kev hloov pauv hluav taws xob rau cov piam thaj oxidase bioanodes hauv biofuel hlwb raug tshawb xyuas.Bromophenol Blue, Bromothymol Blue, Bromocresol Green tau muab piv rau bioelectrochemically tawm tsam ob tus neeg sib kho, benzoquinone thiab ferrocene carboxy aldehyde.Cov kev tshawb fawb biochemical tau ua tiav hauv cov ntsiab lus ntawm enzymatic oxidation, enzyme affinity, catalytic efficiency thiab co-factor regeneration.Cov yam ntxwv sib txawv ntawm TPM dyes raws li cov neeg kho kom haum xeeb yog txiav txim siab los ntawm cov yam ntxwv hauv oxidation / txo cov txheej txheem kawm electrochemically.Lub reversibility ntawm oxidation / txo cov txheej txheem kuj tau tsim los ntawm kev cia siab ntawm cov voltammetric peaks nrog cov nqi cheb.Tag nrho peb cov dyes tau pom qhov ua tau zoo piv rau FA thiab BQ thaum ntsuas hauv ib nrab ntawm cov roj enzymatic.Potentiodynamic thiab lub zog teb thwmsim pom maxima zog ceev ntawm 32.8 μW cm −2 rau ferrocene carboxy aldehyde ua raws li cov txiaj ntsig zoo sib xws tau txais rau TPM dyes nyob ib ncig ntawm 30 μW cm −2 siv cov piam thaj thiab nruab nrab ntawm 10 mmol L −1 thiab 1.0 mmol L-1. , raws.Txij li thaum tsis muaj tus neeg nruab nrab noj tau pom thaum lub sij hawm bioelectrochemical txheej txheem, thiab kuj zoo redox re-cycled txheej txheem tau tiav, kev siv cov triphenylmethane dyes yog xam tau tias yog kev cog lus piv rau lwm cov kev kho mob siv nrog qabzib oxidase bioanodes thiab / los yog biofuel hlwb.
