摘要：

This article successfully explains the coating of platinum on stainless steel sample (SS304) by simple direct current electrodeposition (DC) and pulse current electrodeposition (PC) method. All parameters of operation like current density temperature, duty cycle and pH were optimized. Various analysis techniques were used to categorize the platinum deposited sample, including electron dispersive spectroscopy, scanning electron microscopy and atomic force microscopy. Platinum-coated samples show excellent photocatalytic activity towards methylene blue. PC-coated sample shows better dye degradation performance than DC-coated sample which was monitored by using UV-Vis spectrophotometer.
