BiVO4/CuBi2O4 heterojunction photoanodes with enhanced charge separation for efficient photoelectrochemical water splitting

Enhanced Photoelectrochemical Water Splitting through Synergistic Carrier Separation and Transfer in TiO2-Ferrihydrite-MXene Nanowire Arrays

“…ε s and ε 0 of rutile TiO 2 are 8.85 × 10 –14 and 1.7 F cm –1 , respectively . The carrier lifetime of the photoanode from TR-PL measurement is calculated via the following equation: where τ 1 and τ 2 respectively refer to the three types of decay including exciton radiation recombination, local environmental quenching process, and defect state carrier capture; A 1 and A 2 are related to the contribution ratio of the above three decay components …”
