adsorption is a fundamental process in the physicochemical treatment of wastewaters which industries employ to reduce hazardous organic and inorganic wastes in effluents. in recent years the use of low-cost adsorbents has been widely investigated as a replacement for the currently costly methods of removing heavy metal ions from wastewater. it is well-known that cellulosic waste materials can b...

the use of orange peel as low-cost and eco-friendly adsorbents has been investigated as an ideal alternative to the current expensive methods of removing dyes from wastewater. this paper concerns with the removal of blue 56 from aqueous solutions by orange peel. the effects of ph , initial concentration, adsorbent dosage, and particle size of adsorbent, temperature and also isotherm data analys...

A low-cost bimetallic bifunctional 5-5 wt% FeNi/H-Beta-300 catalyst was investigated in solventless hydrodeoxygenation of lignin-derived model compounds isoeugenol or dihydroeugenol the batch and continuous mode. The characterized...

Microbial electrolysis cell (MEC) is a gripping bio-electrochemical device producing H2 gas from renewable biomass while at the same time treat wastewater.  Through extensive global research efforts in the latest decade, the performance of MECs, including energy efficiency, hydrogen production rate (HPR), and hydrogen recovery have achieved significant breakthroughs. However, employi...

The production of novel catalyst support materials could open up new ways to enhance the catalytic activity by reduced catalyst loadings. Nanocomposites composed of conducting polymers reinforced with graphene nanosheets (GNS) or graphite oxide (GO) sheets can be potential fuel cell electrodes as an alternative to commercial fuel cell electrodes. Polymer electrolyte membrane fuel cells (PEMFCs)...

a water soluble, bronsted acid, 5-sulfosalicylic acid as an efficient organocatalyst was used for the synthesis of physiologically active 2-substituted benzimidazole derivatives from o-phenylenediamine and aromatic aldehydes in ethanol at reflux condition. cost-effectiveness, use of non-hazardous solvents, metal free and commercially available catalyst, single-step, environmentally friendly gre...

Here, we reported a strategy of using an eggshell membrane to produce hierarchically porous carbon as low-cost substrate for synthesizing nano-nickel oxide catalyst (C@NiO), which can effective...

The oxidation of primary and secondary alcohols to their respective aldehydes/ketones is one the most important reactions in fine chemistry due industrial application these products. Based on this, a large number new catalysts oxidants have been tested using this reaction as catalytic model, mainly looking for process that ensures high aldehyde selectivity. In paper, we used moisture stable bor...

a facile and efficient protocol for the synthesis of 1,8-dioxo-octahydroxanthenes has been developed by one-pot knoevenagel condensation, michael addition and cyclodehydration reaction of dimedone (active methylene carbonyl compound) with aromatic aldehydes in the presence of iron (iii) sulfate hydrate as a solid acidic catalyst under solvent-free conditions. various aromatic aldehydes were uti...
