ADSORPTION OF p-NITROPHENOL IN THREE DIFFERENT ACTIVATED CARBONS AT DIFFERENT pH
Adsorption of p-Nitrophenol by three different activated carbons (F100, S.E.I. and B.D.H.) was carried out at 301 K and at controlled pH conditions. Two different adsorption models (Langmuir model and Freundlich model) were studied and compared. The adsorption capacity of the carbons depends on the Point of Zero Charge (PZC) and surface area of the carbons. Adsorption of the solute at higher pH...
متن کاملPoverty amid plenty.
Clinical handoffs are tools aimed at bridging gaps that occur during transitions in care, whether across time (eg, shift changes) or across organisational boundaries (eg, the ward to the intensive care unit). They have long been viewed as potential threats to safety and are attracting increasing attention for several reasons. First, from a control theory point of view, handoffs are inherently h...
متن کاملDesign and Preparation of Electrocatalysts Based on Ordered Mesoporous Carbons for Oxygen Reduction Reaction
The research presented in this dissertation is aimed at the development of electrocatalysts for the oxygen reduction reaction (ORR) based on ordered mesoporous carbons (OMCs). The ORR is a key reaction in electrochemical energy devices such as fuel cells and metal-air batteries. Because of its sluggish kinetics compared to its counterpart reaction (i.e., hydrogen oxidation reaction in fuel cell...
متن کاملReactions of nitrogen and oxygen surface groups in nanoporous carbons under inert and reducing atmospheres.
The reactions of surface functional groups have an important role in controlling conversion of char nitrogen to NOx during coal combustion. This study involved an investigation of the thermal stability and reactions of nitrogen surface functional groups in nanoporous carbons. Four suites of carbons, which were used as models for coal chars, were prepared with a wide range of nitrogen and oxygen...
متن کاملHeteroatoms ternary-doped porous carbons derived from MOFs as metal-free electrocatalysts for oxygen reduction reaction
The nitrogen (N), phosphorus (P) and sulphur (S) ternary-doped metal-free porous carbon materials have been successfully synthesized using MOFs as templates (denoted as NPS-C-MOF-5) for oxygen reduction reaction (ORR) for the first time. The influences of porous carbons from carbonizing different MOFs and carbonization temperature on ORR have been systematically investigated. Due to the synergi...
