Potassium alum (KAl(SO4)2.12H2O), commonly known as ‘alum’, has recently drawn the attention of synthetic chemists as an efficient, safe and eco-friendly acid catalyst in implementing a large number of organic transformations, thereby generating interesting molecular frameworks. The present review article offers an overview of the potent catalytic applications of this commercially available and low-cost inorganic sulfat Read More

The reduction of carbon dioxide has gained much attention due to increasing environmental concerns about global warming associated with carbon emissions from industrial effluents and public transport etc. In this regard, considerable attention has been devoted to the chemical conversion of carbon dioxide, and its incorporation into synthetic organic molecules under mild and “green” conditions. In recent years, significant effo Read More

Biomass, as the most abundant and renewable organic carbon source, can be upgraded into various value-added platform molecules. To implement more sustainable and economic catalytic biomass valorization, reusable heterogeneous catalysts would be one of the preferable choices. In this work, a series of phosphotungstic acid-based solid hybrids were produced by assembly of phosphotungstic acid with diffe Read More

A green and environmental–friendly method for the removal of the hazardous bromothymol blue from aqueous solution was considered applying a hydrophilic, biocompatible and biodegradable natural sorbent of Latvian sphagnum peat moss, applying shaking-dispersive solid-phase extraction. First, the influence of shaking speed was evaluated at 300, 600, 900 U. Furthermore, the optimum conditions of dye-adsorption, such as Read More

We describe herein the use of glycerol as an efficient and sustainable approach for the synthesis of 2-amino-1, 8-naphthyridine-3-carbonitriles and 2-amino-3-quinolinecarbonitriles. The catalyst- free reactions occur straightforwardly using biodegradable and non-hazardous solvent. It is a strategy to address mounting environmental concerns with current approach includes the use of environmentally benign solvent, simple Read More

Polyaniline supported palladium catalyst was applied in the reductive degradation of organic dyes such as Methylene Blue, Rhodamine B, and Methyl Orange in presence of sodium borohydride as an environmental-friendly approach. Role of pH, catalyst amount, and catalyst support were investigated thoroughly to achieve complete and efficient degradation within few minutes under ambient condition. Heterogeneous natu Read More
