A heterogeneous catalyst is a functional material that continually creates active sites with its
reactants under reaction conditions. These sites change the rates of chemical reactions of …

The mitigation of climate change, abatement of greenhouse gas emissions and thus,
fundamentally, the separation of CO 2 from various gas streams are some of the most …

Adsorption of organic molecules from dilute aqueous solutions on carbon materials is a
complex interplay between non-electrostatic and electrostatic interactions. Non-electrostatic …

Carbon fiber reinforcements with an excellent mechanical performance to weight ratio are
primarily preferred for advanced composite applications. The poor interfacial adhesion …

A NaOH-activated carbon was prepared from macadamia nut shell using the impregnation
ratio of 3: 1 (NaOH: char)(wt: wt). The obtained material (AC M) was characterized by several …

Chars originating from the burning or pyrolysis of vegetation may significantly sorb neutral
organic contaminants (NOCs). To evaluate the relationship between the char composition …

In the first stage on the effectiveness of various operating factors such as: adsorbent dose,
contact time, solution pH, initial concentration and temperature on the sorption of heavy …

Chelating groups are successfully linked to graphene oxide (GO) surfaces through a
silanization reaction between N-(trimethoxysilylpropyl) ethylenediamine triacetic acid (EDTA …

Coconut (Cocos nucifera) shell was chemically treated with sulfuric acid (H2SO4) to produce
acid-factionalized biosorbent for methylene blue (MB) dye removal from aqueous …

This study investigates the potential use of activated carbon prepared from coffee waste
(CW) as an adsorbent for the removal of congo red dye from aqueous solution. The oxygen …
