Webb通过理论计算，进一步验证了MgAl-LDH在局部pH调整中的作用。水在MgAl-LDH上很容易解离，随着MgAl-LDH被引入Cu催化剂表面，由水解离产生的增强pH将有助于CO2RR转化为C2+产物。动力学结果表明，水由于解离能垒较低，更倾向于在MgAl-LDH上发生分离。 aha effekt clipart https://adrixs.com

Webbas a function of pH. In soil systems where there may be an external (to the carbonate system) control on pH it would be handy to know the distribution of the carbonate species given pH. This distribution of carbonate species can be derived from the Henderson-Hasslebach relationship knowing pH and pK’s. A slightly different approach is shown next.
