Standard Nitrogen Adsorption Data for Manganese Oxide and like (CBET = 40–60) Surfaces

Oxygen Adsorption on Nitrogen Containing Carbon Surfaces

Introduction The reaction of O2 with carbonaceous surfaces has been widely studied due to its important application in industry. In general, O2 is first chemisorbed on an electron-rich site of the carbon basal plane of graphite and then, it dissociates into oxygen atoms. Oxygen will diffuse on the surface until finds a structural defect to form covalent bonds. If temperature is appropriated, CO...

Adsorption Mechanism of Lead on Wood/Nano-Manganese Oxide Composite

Discharge of untreated industrial wastewater containing heavy metals such as Pb2+ is hazardous to the environment due to their high toxicity. This study reports on the adsorption, desorption, and kinetic study on Pb2+ removal from aqueous solutions using wood/Nano-manganese oxide composite (WB-NMO). The optimum pH, contact time and temperature for adsorption were found...

Representation of Adsorption Data for the Case of Energetically Heterogeneous Solid Surfaces Using Artificial Neural Network

Nitrogen adsorption and desorption at iron pyrite FeS2{100} surfaces.

We have investigated the interaction of nitrogen with single-crystal iron pyrite FeS(2){100} surfaces in ultra-high vacuum. N(2) adsorbs molecularly at low temperatures, desorbing at 130 K, but does not adsorb dissociatively even at pressures up to 1 bar. Atomic surface N can, however, be obtained with nitrogen ions and/or excited neutral species, generated by passing N(2) through an ion gun. S...

Metal Oxide Surfaces: Electronic Structure and Molecular Adsorption

The surface science of oxides has received considerably less attention than the study of metal surfaces. We review some of our work on structural characterization and electronic structure investigations on oxide surfaces which we prepare as thin oxide films on metallic substrates. This preparation method leads to certain experimental advantages concerning the application of electron spectroscop...
