1. Introduction Click to copy section linkSection link copied! With the global efforts for fully renewable energies and responsible use of resources, electrocatalysts for water splitting are in focus with the need to minimize the use of platinum group metals (PGM). Nickel, as an abundant resource, is predestined as an electrocatalyst for use in hydrogen production due to its generally high catalytic activity, but suffers from compromised stability, especially in acidic media.
