POM-based catalysts have wide applications in catalytic biomass refinery.

Ni catalysts supported on Nano porous catalysts were prepared by the impregnation method and tested for vapor phase hydrogenation of benzene. The textural and physico-chemical properties of Ni catalysts were characterized by the X-ray diffraction, Fourier-transform infrared spectroscopy, scanning electron microscope and N2 adsorption-desorption analysis. The catalytic evaluation reve...

The water-gas shift reaction (WGS: CO + H2O  H2 + CO2) is a critical process in providing pure hydrogen for fuel cells and other applications. Improved air-tolerant, cost-effective WGS catalysts for lower temperature processing are needed. Ceria-, titaniaand molybdena-based catalysts are expected to be the next generation of WGS catalysts for industrial applications. The design and optimizatio...

In this study ternary Ni-P-CeO2 catalysts were first synthesized by the Co-electrodeposition method on a copper substrate and then characterized by means of microstructural and electrochemical techniques toward a hydrogen evolution reaction (HER). Also, for comparison other catalysts such as Ni-CeO2, Ni-P, and Ni were prepared and characterized by the same methods. The microstructure of the inv...

This review aims to give a general overview of the recent use tungsten-based catalysts for wide environmental applications, with first some useful background information about tungsten oxides. Tungsten oxide materials exhibit suitable behaviors surface reactions and catalysis such as acidic properties (mainly Brønsted sites), redox adsorption (due presence oxygen vacancies) photostimulation res...

• Catalyst recovery can be performed in an energy-efficient way by reducing the volume of distillation streams. • Temperature-sensititve catalysts can be recovered at relatively mild temperatures from high boiling compounds. • By enabling continuous operation, reactions can be run under steady-state conditions, e.g., at limited conversions. • Catalysts based on expensive metals or ligands can b...

A novel class of primary amine-metal Lewis acid bifunctional catalysts based on a bidentate ligand was developed. These catalysts were highly efficient in catalyzing the direct asymmetric aldol reactions of ketones offering excellent stereoselectivity. The aldol reactions required a low catalyst loading (2.5 mol%), and were water compatible.
