Question

1. Use a catalyst to split water molecules at a lower energy
2. Increase the energy used in water electrolysis
3. Use a metal-based catalyst in other sectors
4. Reduce the number of intermediate steps in the reaction cycle

Answer 1

Answer: (1) Use a catalyst to split water molecules at a lower energy

 

Explanation: The article mentions that the traditional solution to reduce energy consumption in water electrolysis is to use a catalyst to induce water molecules to split at a lower energy.
