When Alpha met Beta : A tuneable α—β surface phase junction on Ga 2 O 3 can significantly improve photocatalytic overall water splitting into H 2 and O 2 over individual α‐Ga 2 O 3 or β‐Ga 2 O 3 surface phases. This enhanced photocatalytic performance is mainly attributed to the efficient charge separation and transfer across the α–β phase junction.
