An electrocatalyst including carbon and a nanosheet supported on the carbon. The nanosheet includes a metal ruthenium nanosheet, and a platinum atomic layer formed on an entire surface of the metal ruthenium nanosheet. The metal ruthenium nanosheet is a monoatomic layer, and the platinum atomic layer is a monoatomic layer or a monoatomic layer laminated body.

Electrocatalyst

A core-shell structure nanosheet includes a metal ruthenium nanosheet, and a platinum atomic layer provided on a surface of the metal ruthenium nanosheet. An electrocatalyst includes carbon, and the core shell structure nanosheet supported on the carbon. A method for manufacturing an electrocatalyst includes applying a ruthenium oxide nanosheet colloid which comprises a ruthenium oxide nanosheet, on carbon to obtain a carbon-supported ruthenium oxide nanosheet, in which the ruthenium oxide nanosheet is supported on the carbon. The carbon-supported ruthenium oxide nanosheet is reduced to obtain a carbon-supported ruthenium metal nanosheet, in which a ruthenium metal nanosheet is supported on the carbon. A platinum atomic layer is provided on a surface of the metal ruthenium nanosheet to obtain the electrocatalyst.
