To achieve the efficient resource treatment of aromatic volatile organic compounds (VOCs) high toxicity, this work chose anisole as a representative pollutant and investigated its removal by an MCM–41-supported sulfuric acid (SSA/MCM–41) adsorbent. The results indicate that SSA/MCM–41 adsorbent exhibited reactive temperature range 110–140 °C, in which ratio (Xa) was greater than 95%. collected ...

new type of heterogeneous nanocatalyst for deoximation based on tungsten oxide supported on mesoporousmolecular sieve mcm-41 was developed. this new system representes inexpensive and highly activeheterogeneous nanocatalyst for deoximation under green and mild reaction conditions.

Al-MCM-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. The reaction was efficiently promoted by 10 mg nano-Al-MCM-41 and the heterogeneous catalyst was recycled for four runs in this reaction with...

In this project various types of carbonyl compounds were efficiently converted to their corresponding 1,3-oxathiolanes  with 2-mercaptoethanol in the presence of catalytic amount of Al-MCM-41 with microwave energy. The catalyst can be reused several times without loss of its catalytic activity. Very short reaction times, reusability of the catalyst, and easy workup are noteworthy advantages of ...

Functionalized polyethylene-based nanocomposites were prepared by in situ polymerization of ethylene with modified or neat MCM-41 nanoparticles (NMCM-41). Two different synthetic approaches investigated to improve the compatibility between hydrophobic HDPE matrix and hydrophilic NMCM-41: (i) incorporation UA into polymeric copolymerization ethylene, promoted zirconocene catalyst under homogeneo...
