Abstract: A novel organic–inorganic coordination polymer [CdCl3(CH3)3NH] 1 was synthesized by the reaction of CdCl2 with trimethylamine (TMA) at 170 °C for 5 days in ethanol and structurally characterized by means of X-ray single diffraction. The title compound affords a one-dimensional chain structure. It crystallizes in hexagonal system space group with , , , , , , , , , , the final and for 355 observed reflections with . The title compound consists of cation [(CH3)3NH]+ and anion chain , and they are combined by static attracting forces in the crystal. TG–DTA, XRD and IR data for the title compound are reported and discussed. The photoluminescent properties of the compound 1 were also investigated. [Copyright &y& Elsevier]

A novel 2D/3D Z-scheme g-C 3 N 4 /SnS 2 photocatalyst was successfully fabricated via self-assembly forming 3D flower-like SnS 2 microspheres on the surface of the 2D g-C 3 N 4 nanosheets. The photocatalytic performances of the samples were systematically explored through catalytic reduction of Cr 6+ and oxidation of Bisphenol S (BPS) under the illumination of visible light, and the photocatalytic degradation pathway of BPS was also proposed based on the degradation products confirmed by GCMS. Among the as-prepared samples, 0.4-g-C 3 N 4 /SnS 2 exhibited the most efficient photocatalytic performances, and the apparent quantum efficiency (QE) for the removal of Cr 6+ could achieve 30.3 %, which is 2.8 times higher than that of the SnS 2 . The enhancing photocatalytic activities originated from the efficient interfacial charge migration and separation obtained in g-C 3 N 4 /SnS 2 , which was firstly verified via the photoluminescence spectra, time-resolved photoluminescence spectra and photoelectrochemical characterizations. Importantly, the DFT calculated shows that the band distribution of the g-C 3 N 4 /SnS 2 sample is staggered near the forbidden, which can facilitate the efficient interfacial charge migration and separation as well as result in the improvement of the catalytic activity. Finally, we put forward a more reasonable Z-scheme charge transfer mechanism, it was verified by analysing the results of free radical scavenging tests, EPR experiments and theoretical calculations., (Copyright © 2020 Elsevier B.V.
