網頁In base catalysis, the catalyst is usually an OH − \text{OH}^-OH − start text, O, H, end text, start superscript, minus, end superscript ion. An example of a reaction that can be catalyzed by acid is the hydrolysis of sucrose, also known as table sugar. 網頁SCR technology is considered to be the most effective method for denitrification. However, low NOx conversion rate of the current catalysts at low temperatures limits their further application. Herein, Sn-doped modified CoAl-LDH carriers are synthesized by hydrothermal method, and the typical hexagonal sheet
