Novel β-In_2.77S₄ nanosheet-assembled hierarchical microspheres: synthesis and high performance for photocatalytic reduction of Cr(<scp>vi</scp>)

Abstract

A novel nanosheet-assembled hierarchical sulfur deficient β-In_2.77S₄ microsphere photocatalyst was prepared, and the β-In_2.77S₄ microsphere shown high visible light photocatalytic activity in the reduction of aqueous Cr(<sc>vi</sc>).
