For a long time, there has been global concern over the environment and energy problems. Recently, the problems, which have brought about serious effect on the global living condition, have been in the “spotlight” and given impetus to the universal’s efforts to head for the same direction: stem the worst warming and strive for the renewable energy source . Hydrogen peroxide (H 2 O 2 ) is undoubtedly a good choice, which holds the promise as a clean, efficient, safe and transferrable energy carrier. Octahedral coordination polymer , Cd 3 (C 3 N 3 S 3 ) 2 , was found to be a robust photocatalyst for H 2 O 2 generation under visible light irradiation . To further improve the H 2 O 2 generation efficiency, adhering the octahedron to reduced graphene (rGO) was applied as the strategy herein. The study shows that by adhering Cd 3 (C 3 N 3 S 3 ) 2 to rGO , the formation of H 2 O 2 is 2.5-fold enhanced and its deformation is concurrently suppressed. This work not only demonstrates the effectiveness of adhering Cd 3 (C 3 N 3 S 3 ) 2 polymer to rGO for the improvement of the polymer’s photocatalytic performance, but also proposes a general way for the fabrication of graphene/coordination compound hybrids for maximizing their synergy.
As an efficient and sustainable technology, photocatalysis driven by visible light has made great contributions to the removal of heavy metals from environment. In this work, a series of Cd 3 (TMT) 2 /CdS heterojunction composite photocatalysts were prepared by self-formation of CdS nanoparticles using an octahedral coordination polymer Cd 3 (C 3 N 3 S 3 ) 2 (denoted as Cd 3 (TMT) 2 ) as a precursor. The photocatalytic performance of Cd 3 (TMT) 2 /CdS heterojunction composites for Cr(VI) has been significantly improved under visible light irradiation owing to effective separation and migration of photoexcited charge carriers. Moreover, Cd 3 (TMT) 2 /CdS composites exhibited remarkable photocatalytic reduction performance of Cr(VI) solution with high concentration. This photocatalyst provides a novel route in the photoreduction of Cr(VI).
