Structural Changes of Mo/ZSM-5 Catalysts During the Methane Dehydroaromatization

Eurasian Chemico-Technological Journal, 2010
The structure changes of Mo/ZSM-5 catalysts with different Mo content (2 and 10 wt. % Mo) and Si/Al atomic ratio (17, 30 and 45) during the methane dehydroaromatization have been investigated by X-ray powder diffractometry, N2 adsorption and transmission

Ligand engineering to achieve enhanced ratiometric oxygen sensing in a silver cluster-based metal-organic framework

Nature Communications, 2020
Incorporating dual fluorescence and phosphorescence into a single matrix is attractive for oxygen sensing, but material design is challenging. Here the authors achieve dual fluorescence-phosphorescence from a single linker chromophore in a silver ...

Tuning graphitic oxide for initiator- and metal-free aerobic epoxidation of linear alkenes

Nature Communications, 2016
Graphitic oxide is readily produced by the oxidation of graphite. Here the authors show that the amount and nature of the oxidant can be used to tune the properties of graphitic oxide, and furthermore report a carbocatalyst for alkene epoxidation without

Methane dry reforming over Ni catalysts supported on Ce–Zr oxides prepared by a route involving supercritical fluids

Open Chemistry, 2017
Ce0.5Zr0.5O2 mixed oxides were prepared in a flow reactor in supercritical isopropanol with acetylacetone as a complexing agent. Variation of the nature of the Zr salt and the temperature of synthesis affected the phase composition, morphology and ...
