A kinetic model for distinguishing between direct and indirect interfacial hole transfer in the heterogeneous photoxidation of dissolved organics on TiO2 nanoparticle suspension

Article Abstract:

A kinetic model is presented for assessing the photocatalytic degradation of water-dissolved pollutant species at suspension of TiO2 nanoparticles. The model is based on the sequence of reactions occurring at the semiconductor/electrolyte interface under illumination, and emphasizes the degree of electronic interaction of dissolved pollutant species with the semiconductor surface.

Thermochemical hole burning on DPA(TCNQ)2 and MEM(TCNQ)2 charge transfer complexes using a scanning tunneling microscope

Article Abstract:

A thermochemical hole burning effect is observed on two organic charge transfer complexes, which is closely related to a STM current-induced localized thermochemical decomposition of the charge-transfer complex. The decomposition reaction evolves the low boiling point decomposition components of the charge-transfer complex leaving a nanometer-sized hole on the crystal surface.

Thermal Decomposition of metal nitrates in air and hydrogen environments

Article Abstract:

The study was done on the decomposition of metal nitrates in air by thermogravimetry. The result shows that their reduction may be triggered by thermal decomposition.
