| 제목 | Optimization of porous BiVO4 photoanode from electrodeposited Bi electrode |
| 초록 | BiVO4 photoanode is prepared via the chemical reaction of electrodeposited Bi metal electrode with a vanadium precursor, and the electrodeposition conditions for the Bi electrode are modified to optimize the resultant BiVO4's photoelectrochemical performance. The nucleation and growth kinetics of Bi dendrites are varied by changing the applied potential and temperature during electrodeposition. The decrease in particle size and increase in porosity and active facet exposure under optimized conditions are responsible for the improved photoelectrochemical performance. The photocurrent density of BiVO4 prepared under optimized condition is over 5 mA cm−2 at 1.25 VRHE for sulfite oxidation; this represents an improvement of almost 2.5 times compared to that of non-optimized BiVO4. Therefore, the structural effect of BiVO4 on the performance can be elucidated clearly. This poster review the 'Electrochim. Act. 189 (2016) 252-258' |
