This study is led by Pro. Ya-Qian Lan, Dr. Lei Zhang and Dr. Run-Han Li (Guangdong Provincial Key Laboratory of Carbon Dioxide Resource Utilization, School of Chemistry, South China Normal University). Researchers have synthesized two novel single crystals, uc-Ni5-Co4 and c-Ni5-Co4, by co-assembling reductive Ni5 and oxidative Co4-POM clusters. In c-Ni5-Co4, two Ni5 and one Co4-POM are connected by bridging-oxygen atoms symmetrically, while the structural motifs in uc-Ni5-Co4 are stacked with hydrogen bond interactions.
THE SCHEMATIC REPRESENTATION OF ONE-POT SYNTHESIS OF N-BENZYLIDENEANILINE DERIVATIVES BY TRI-FUNCTIONAL MOLECULAR JUNCTION PHOTOCATALYSTS IN A PHOTOCATALYTIC CASCADE SYSTEM.
The powder X-ray diffraction (PXRD) tests showed that the experimental peaks of uc-Ni5-Co4 and c-Ni5-Co4 crystals were consistent with their simulated patterns, indicating their high crystallinity and purity. X-ray photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), and inductively coupled plasma (ICP) were performed to verify the existence and abundance ratios of Co and Ni elements. All the results proved that during the post-synthesis process, Ni5 and Co4-POM did not decompose or recombine, as well as the accuracy of the structure determined by single-crystal X-ray diffraction (SCXRD).
This work introduces a strategy for conducting value-added reactions under mild conditions by harnessing photogenerated electrons and holes simultaneously. It also paves the way for the industrial production of high-value organic compounds using photocatalytic cascade systems and the development of supported metal-cluster catalysts.
