A ternary photocatalyst, graphene based bismuth modified bismuth(III) oxybromide (Bi/BiOBr/G), was synthesized via a facile one-step solvothermal method using only ethylene glycol as both solvent and reducing reagent. Bi/BiOBr/G exhibits higher photocatalytic activity than bismuth(III) oxybromide (BiOBr) on degradation of Rhodamine B under visible-light illumination, and the photodegradation rate is 4.9 times that of BiOBr. The enhanced photocatalytic activity is attributed to the synergistic effect among Bismuth, graphene and BiOBr, which can effectively promote the visible-light absorption of Bi/BiOBr/G and the separation of photogenerated charge carriers. The conditions influencing the photocatalytic performance of Bi/BiOBr/G were also investigated in detail, as well as the photocatalytic mechanism of the degradation. (C) 2019 Elsevier B.V.

Hui Xu, Cheng Wang, Guangyu He, Haiqun Chen

Summary: In this study, a novel class of two-dimensional trimetallic MOF nanosheets with abundant active sites and facilitated mass and electron transfer channels was developed as efficient electrocatalysts for boosting oxygen evolution reaction (OER). The unique 2D nanosheet structure enlarged the active area, and the organic ligand in the MOF served as a pillar to enlarge the interplanar space for ion and electron transportation. The synergistic effect between multi-metal active sites effectively promoted the electrocatalytic activity. After an electrochemical activation process, the optimized NiFeZn MOF nanosheets showed outstanding OER performance with low overpotential and small Tafel slope. This method is also universal for the synthesis of the NiFe-MOF family.

Summary: Efficient and selective oxidation of arene C-H bonds has long been a challenging goal.

The SACu-NRGO exhibits excellent catalytic performance with a selectivity of 98.6% towards phenol, thanks to the fully exposed and homogeneously dispersed CuN3 active sites anchored by adjacent pyrrolic N atoms in the NRGO skeleton. Furthermore, the structure of the single-atom active sites and the mechanism of the oxidation process are elucidated in depth through DFT calculations.
