SnNb2O6/NiCo-LDH Z-scheme heterojunction with regulated oxygen vacancies obtained by engineering the crystallinity for efficient and renewable photocatalytic H2 evolution

SnNb 2 O 6 /NiCo-LDH Z-scheme heterojunction with abundant oxygen vacancies exhibited highly activity and stability toward photocatalytic H 2 evolution, ascribed to the regeneration of oxygen vacancy by engineering the crystallinity.
