| 英文摘要 | An earth-abundant, low-cost cobalt porphyrin complex (cotcpp) is designed as a molecular catalyst to work on three-dimensional bivo4 film electrode for water oxidation for the first time. under illumination of a 100 mw cm(-2) xe lamp, the cotcpp-functionalized bivo4 photoanode exhibits a 2-fold enhancement in photo current density at 1.23 v vs rhe and nearly a 450 mv cathodic shift at 0.5 ma cm(-2) photocurrent density relative to bare bivo4 in 0.1 m na2so4 (ph = 6.8). simultaneously, stoichiometric oxygen and hydrogen are generated with a faradic efficiency of 80% over 4 h. the activity and stability of the bivo4 photoanode are dramatically increased by molecular cotcpp, giving rise to higher performance than previously reported noble metal ruthenium complex-modified bivo4 photoanode. by using hydrogen peroxide as the hole scavenger, we demonstrate that molecular cotcpp catalyst greatly suppresses the hole-electron recombination on the surface of bivo4 semiconductor, which offers a promising route toward high efficiency, low cost, practical solar fuel generation device. |
