Summary: In the catalytic process of semiconductors, the rapid recombination of electron-holes greatly reduces the catalytic activity. A low-defect reduced hydroxylated graphene (RGOH) was used as a carrier material to prepare TiO2/reduced hydroxylated graphene (T/RGOH) nanocomposite photocatalyst, which showed a higher degradation efficiency for methylene blue compared to pure TiO2 and TiO2/reduced graphene oxide (T/RGO) nanocomposite photocatalysts. The enhanced performance was attributed to the higher electrical conductivity of RGOH and the existence of Ti-O-C bonds in the T/RGOH, which improved electron-hole separation and prevented rapid recombination.

Summary: In this article, a pair of isostructural graphene-like 2D coordination polymers (GCPs) synthesized by the coordination of benzenehexathiol (BHT) ligands with Cu(I) and Cu(II) ions, respectively, is reported. Spectroscopic characterizations indicate the coexistence of Cu(I) and Cu(II) in both GCPs with a near 1:1 ratio and a fractional oxidation state of +1.5 on average, forming a unique pair of Creutz-Taube mixed-valence 2D structures. Density functional theory calculations uncover an intramolecular pseudo-redox mechanism where the radicals on BHT ligands can oxidize Cu(I) or reduce Cu(II) ions upon coordination, leading to isostructures with distinct electron configurations. This study demonstrates for the first time that Cu(I) or Cu(II) can be used to achieve 2D isostructures, suggesting the possibility of neutral periodic structures hosting different numbers of total electrons as ground states, which may have implications for 2D materials.

Summary: A novel magnetic composite was synthesized by attaching amino-functionalized magnetic particles to cellulose nanofibers grafted with polyethyleneimine. The composite exhibited exceptional adsorption capabilities for heavy metal ions, with high adsorption capacities for Pb, Cu, and Co. The introduction of PEI significantly enhanced the adsorption capacities, and the adsorption sequence can be explained by differences in ionic radius and surface complexation strength.
