Novel Visible-Light-Driven Photocatalyst Based on Mn−Cd−S for Efficient H2 Evolution

The hydrothermally synthesized Mn1−xCdxS with a high Mn content (x ∼ 0.1) showed the high photocatalytic activity for H2 evolution from a 0.1 M Na2S−0.5 M Na2SO3 solution under visible light irradiation (λ > 420 nm).
