Effectiveness of this alloy in hydrogen evolution reaction (HER) influenced by its intrinsic properties. Deposit of Ni-Fe alloy was prepared on stainless steel substrate by direct current (DC) electrodeposition. The phase of deposits characterized by Powder X-ray Diffraction (PXRD) with values of 2θ at 44.03 and 51.28 according to CIF reference of Ni3Fe crystalline phase. The effectiveness of Ni-Fe alloy simply measured by volume of hydrogen gas produced from alkaline water electrolysis reaction using Hofmann voltameter. The rate of production hydrogen gas of Ni3Fe alloy in 0.10 M KOH at room temperature was 0.010 cc/minutes at 1.5 V and 3 mA. It has better electrocatalytic activity than nickel deposit to produce hydrogen gas in alkaline water electrolysis. Hofmann voltameter is simple tool can applied to introduce electrocatalytic subject in chemistry learning.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]alkaline water electrolysis,electrocatalytic material,Hofmann Voltameter,Ni-Fe alloy[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]The authors would like to acknowledge Institut Technology of Bandung and partial financial support from PDUPT DIKTI period 2018-2019.
