Solid acid catalysts, which have favorable characteristics such as efficient activity, high selectivity, long catalyst life and ease in recovery and reuse, have great potential for efficiently transforming lignocellulosic biomass into biofuels and can replace many conventional liquid acids for hydrolysis and pretreatment. This work briefly introduces conventional biomass pretreatment and hydrol...

In this paper, we analysed the influence of corrosion processes and addition a carbon black-heteropoly phosphomolybdic acid (C45-MPA) nanocomposite on operating parameters hydride electrode obtained basis intermetallic compound La2Ni9Co. The electrochemical properties negative electrodes for NiMH batteries were studied using galvanostatic charge/discharge curves, potentiostatic method, impedanc...

Keggin-type heteropolyacid cesium salts have been regarded as potential candidates for heterogeneous catalytic reactions. This review describes the success of heteropolyacids (Cs-HPA salts) efficient catalysts in various synthesis processes. The Cs-HPA can be synthesized solid through metathesis a solution containing precursor HPA and another soluble Cs salt, which will give salt precipitate. A...

The Friedel-Crafts acylation of furan to produce 2-acyl by using acetic anhydride is industrially important but it uses highly polluting liquid acids as catalysts. In this study, supported modified heteropoly were used heterogeneous catalysts in a solventless green process. Metal exchanged dodecatungstophosphoric acid (DTP) was loaded on three different supports, and its effect evaluated. 20% w...

The hydroamination reaction offers a very attractive route for the synthesis of alkylated amines and their derivatives with no byproduct formation. Heterogeneous intermolecular hydroamination reactions of alkynes with aromatic amines using different inexpensive copper salts of hetropolyacid catalysts were investigated. Among heteropoly salts, copper salts of silicotungstic acid showed highest a...
