Abstract
The present application relates to a catalyst for hydrogen evolution reaction (HER) including a transition metal matrix and noble metal atoms formed in the transition metal matrix, in which the noble metal atoms have oxygen adsorbed thereto, and oxygen is derived from the transition metal matrix.
Claims19
A catalyst for hydrogen evolution reaction (HER) comprising a transition metal matrix and noble metal atoms formed in the transition metal matrix, wherein the noble metal atoms have oxygen physisorbed thereto, and the oxygen is derived from the transition metal matrix.
A method for preparing a catalyst for hydrogen evolution reaction (HER), the method comprising the steps of:
- immersing a transition metal matrix in a noble metal chloride solution;
- preparing an intermediate by exchanging noble metal cations of the noble metal chloride solution with a portion of metal cations of the transition metal matrix;
- immersing the intermediate in a solution containing a reducing agent;
- and
- forming noble metal atoms to which oxygen is physisorbed on the transition metal matrix by moving oxygen of the transition metal matrix to noble metal atoms by the reducing agent.
