Bi2WO6 microelectrode arrays on FTO glass substrates were fabricated by a picoliter solution dispensing technique using Bi(NO3)3 as the Bi source and (NH4)6H2W12O40 as the W source in ethylene glycol. The scanning electrochemical microscope modified by using an optical fiber in place of an ultramicroelectrode was employed for rapid screening of the Bi2WO6 arrays and to investigate the effect of...
