A novel bismuth hydroxide (Bi(OH)3) semiconductor with highly-efficient photocatalytic activity

Herein, a novel Bi(OH)₃ photocatalyst was successfully synthesized. Benefiting from the suitable band positions, abundant alkaline groups and oxygen vacancies, the as-prepared semiconductor exhibits efficient activity in both photocatalytic CO₂ reduction with a CO production rate of 36 μmol g^-1 h^-1 and phenol decomposition with a 92.7% degradation rate in 180 min.
