摘要
The possible role of gas phase transport in oxygen spillover has been investigated by two methods based on different principles, viz.: 1. Comparison of CO2 formation at different temperatures (570 - 830 K) using GC; 2. Imaging experiments (burning of carbon opposite to a characteristic pattern of Pt, evaporated to glass. Both techniques clearly show that activated oxygen (probably oxygen atoms) may migrate via the gas phase and react with carbon.
