The effect of urea on microstructures of Ni3S2 on nickel foam and its hydrogen evolution reaction
چکیده انگلیسی


• Urea promoted to forming more Ni3S2 nanotube arrays on nickel foam.
• Ni3S2 nanotube arrays showed higher catalytic activity in alkaline solution.
• Ni3S2 nanotube arrays promoted electron transport and reaction during the HER.

The effects of urea concentration on microstructures of Ni3S2formed on nickel foam and its hydrogen evolution reaction were investigated. The Ni3S2 nanosheets with porous structure were formed on nickel foam during hydrothermal process due to low urea concentration. While high urea concentration facilitated the forming of Ni3S2 nanotube arrays. The resulting Ni3S2 nanotube arrays exhibited higher catalytic activity than Ni3S2nanosheets for hydrogen evolution reaction. This was mainly attributed to a fact that Ni3S2 nanotube arrays facilitated diffusion of electrolyte for hydrogen evolution reaction.
