Electrochemical water splitting is a process to store renewable energy in hydrogen, which is a green energy carrier producing only water when combusted. However, the overall electrochemical water splitting is limited by the low efficiency of the anod

Vehicles that run on natural gas must be equipped with an exhaust gas after-treatment system to burn their unavoidable CH4 slip, which must not be released into the environment as CH4 is a potent greenhouse gas. Pd is known as a highly active catalys
