Temperature program desorption (TPD) and temperature program reaction (TPR) study reveals that HCHO is adsorbed on surface of catalyst and HCHO oxidation involves reaction between adsorbed formate species and adsorbed oxygen molecules.

• 程序升温脱附(TPD)和程序升温反应(TPR)的实验证明了甲醛的氧化过程就是吸附在催化剂上的甲酸盐与吸附的氧反应的过程。
