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 (HO) is undoubtedly a good choice, which holds the promise as a clean, efficient, safe and transferrable energy carrier. Octahedral coordination polymer, Cd(CNS), was found to be a robust photocatalyst for HO generation under visible light irradiation. To further improve the HO generation efficiency, adhering the octahedron to reduced graphene (rGO) was applied as the strategy herein. The study shows that by adhering Cd(CNS) to rGO, the formation of HO is 2.5-fold enhanced and its deformation is concurrently suppressed. This work not only demonstrates the effectiveness of adhering Cd(CNS) 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.
长期以来,全球都在关注环境和能源问题。最近,这些对全球生活条件产生严重影响的问题成为了“焦点”,并推动全球朝着同一个方向努力:遏制最严重的气候变暖并争取可再生能源。过氧化氢(HO)无疑是一个不错的选择,它有望成为一种清洁、高效、安全且可转移的能量载体。八面体配位聚合物Cd(CNS)被发现是一种在可见光照射下用于生成HO的强大光催化剂。为了进一步提高HO的生成效率,本文采用将八面体附着于还原氧化石墨烯(rGO)的策略。研究表明,通过将Cd(CNS)附着于rGO,HO的生成增强了2.5倍,同时其分解受到抑制。这项工作不仅证明了将Cd(CNS)聚合物附着于rGO以改善聚合物光催化性能的有效性,还提出了一种制备石墨烯/配位化合物杂化物以最大化其协同效应的通用方法。
