When aged for long times at elevated temperatures, Fe-12Cr steels can experience a significant decrease in the fracture toughness, as observed by an increase in the fracture appearance transition temperature (FATT). The mechanism responsible for this

The influence of deposited Pt metal clusters on the CO photooxidation reaction on the TiO2(110) surface was investigated. An enhancement in the CO photooxidation reaction rate or yield is not observed in the presence of Pt metal clusters on the TiO2(

The photooxidation of chemisorbed CO on TiO2(110) was investigated. Molecular O2, chemisorbed at 105 K at anion vacancy defect sites on TiO2(110), is shown to undergo excitation leading to either photodesorption of O2 or photooxidation of coadsorbed

CO chemisorption has been studied on TiO2(110) under surface conditions where oxygen anion vacancy sites are not present (oxidized surface), compared to conditions where the vacancy sites are present (annealed surface). The binding energy of CO on th

In 1972, Fujishima and Honda discovered the photocatalytic splitting of water on TiO{sub 2} electrodes. This event marked the beginning of a new era in heterogeneous photocatalysis. Since then, research efforts in understanding the fundamental proces

We have investigated the adsorption and thermal conversion of molecular oxygen (O2) states on the TiO2(110) surface by making use of the distinct photodesorption behavior of each adsorption state. Oxygen chemisorbs at the oxygen vacancy defect sites

We report the first experimental observation of two chemisorption states for molecular oxygen on a TiO2(110) surface containing anion vacancy sites. The first molecular species can be photoactivated to oxidize coadsorbed CO to CO2 (α channel) and un
