摘要

Co₃(OH)₂(HPO₄)₂/LaTiO₂N composites with a special microstructure were constructed by in-situ hydrothermally growing Co₃(OH)₂(HPO₄)₂ nano-needles on the surfaces of LaTiO₂N irregular brick-like chunks. An effective heterojunction in the composites was formed based on the matched band structures and the close interfacial combination between Co₃(OH)₂(HPO₄)₂ and LaTiO₂N, and thus improved the separation and transfer of photo-generated carriers. Consequently, photocatalytic O₂-evolution activity of the composites was enhanced up to 3.5 times that of LaTiO₂N.
