In this work, we report that RhB and NO could be effectively removed under visible light with hollow In(OH)(x)S-y nanocubes fabricated at a low temperature of 80 degrees C. The photocatalytic experiments revealed that these low temperature synthesized hollow In(OH)(x)S-y nanocubes were more efficient than P25 and In(OH)(x)S-y counterpart hydrothennally synthesized at 180 degrees C (In(OH)(x)S-y-180). The porous structures, larger surface area, and new valence band of low temperature synthesized hollow In(OH)(x)S-y nanocubes were thought to account for their superior photocatalytic activity. Among all the In(OH)(x)S-y samples, the one with original S/In ratio of 0.500 in synthetic solution exhibited the highest photocatalytic removal efficiencies of RhB, while the other with original S/In ratio of 1.000 removed NO most efficiently. We systematically studied the photocatalytic process of RhB on In(OH)(x)S-y and analyzed their different photocatalytic performances on removing RhB and NO. This study reveals that these hollow In(OH)(x)S-y nanocubes are promising for environmental remediation.
