A novel silica catalyst was synthesized by evaporation-induced self-assembly (EISA) method and tested for the catalytic selective hydrolysis of cellulose to glucose. This silica catalyst exhibited a higher catalytic activity than other oxides prepared by the same method, such as ZrO2, TiO2, and Al2O3. Using silica as a catalyst, cellulose was selectively hydrolyzed into glucose with a glucose y...

Three-dimensional graphene oxide foam (3DGO) was found to be a highly efficient and recyclable catalyst for the oxidation of thioanisole. We found that 3DGO is more efficient than 2DGO, and that the efficiency increases with the number of cycles for 3DGO, in contrast to the 2D counterpart.

The minute amount of hydrogen sulfate groups introduced into the graphene oxide (GO) obtained by Hummers oxidation of graphite renders this material as a highly efficient, recyclable acid catalyst for the ring opening of epoxides with methanol and other primary alcohols as nucleophile and solvent.

A zeolite-catalyzed, simple, one-pot, solvent-free, cost effective, and environmentally benign process for the synthesis of dihydropyrimidones is described. This reaction is scaleable to multigram scale and the catalyst is recyclable. This methodology has resulted in an efficient synthesis of monastrol, a potent inhibitor of kinesin Eg5.

A rapid and efficient synthesis of 4,6-Dimethylpyrimidine-2(1H )-one has been carried out from acetylacetone and urea in dry media in the presence of an environmentally friendly non-corrosive, non-toxic and recyclable catalyst in 85% yield under microwave irradiation conditions.

This review presents a summary of reactions performed using microwave irradiation. This green processes have resulted through use of less or no catalyst, readily recyclable solvents and yield that are often higher than conventional method. It also focus on the principle of microwave activation, various types of Microwave Reactor and its characteristics.

The nitrogen-substituted delaminated ITQ-2 zeolite was found to be a highly active and recyclable catalyst for the Knoevenagel condensation of bulky aromatic aldehydes with ethyl cyanoacetate which cannot take place over the base sites placed within the micropores of conventional zeolites due to spatial limitations.

A novel water-soluble NHC-Pd polymer with triethylene glycol legs was developed as a water soluble and highly recyclable catalyst that shows high catalytic activity in the Suzuki-Miyaura coupling of aryl chlorides in high yields in water at room temperature.

We report a robust and recyclable 'dip-catalyst' based on a gold nanoparticle (Au NP)-loaded filter paper composite, prepared by a simple dip-coating process using concentrated Au NP suspensions in toluene. While acting as catalysts, the composites display excellent surface enhanced Raman scattering (SERS) efficiency, allowing the real-time monitoring of chemical reactions.
