Mechanisms proposed for the gold-catalysed Water-Gas Shift (WGS) are critically reviewed, and a complete reaction set and cycle involving activation of water on reduced support sites is considered; however, a modified route to CO2 formation by thermal decomposition of a carboxyl species results in a simpler and therefore more probable mechanism.

金催化水煤气变换的机理

对金催化水煤气变换 (WGS) 提出的机制进行了严格审查，并考虑了一个完整的反应组和循环，包括在减少的支持位点上活化水；然而，通过羧基物质的热分解形成 CO2 的改进途径导致更简单，因此更可能的机制。
