Temperature-programming desorption (TPD) and temperature-programmed reaction (TPR) have been applied to study the reduction of ¹⁵NO by deuterium on a Pd(110) surface. TPR results show that the reaction occurs in the autocatalytic regime of surface explosion with the rate-limiting step of ¹⁵NO_ads dissociation into highly reactive O_ads and ¹⁵N_ads atoms. The steady-state reaction leads to formation of ¹⁵N₂, D₂O, ¹⁵ND₃ and ¹⁵N₂O products. The phenomena of a reaction rate hysteresis observed during a heating-cooling cycle can be attributed to accumulation of ¹⁵NO_ads at low temperatures followed by surface explosion at T ∼ 490 K. The binding energies and structural parameters of species involved in the NO + H₂ reaction over Pd(110) have been calculated by the DFT technique, and plausible reaction pathways have been considered. NO dissociation from the most stable short bridge site (E_b = −1.94 eV) occurs via the intermediates in on-top and long bridge modes with lower binding energy (E_b = −1.31 to 1.65 eV).

The energy of transition states reaches 0.2–0.26 eV over energy of NO in a gas phase, which confirms the rate-limiting role of NO dissociation. It has been demonstrated that OH_ads-group formation is the rate-limiting step of water molecule generation. Subsequent H₂O formation occurs via disproportionation of the OH_ads intermediates.

程序升温脱附（TPD）和程序升温反应（TPR）已用于研究氘在Pd（110）表面上对¹⁵ NO的还原作用。TPR结果表明，发生在表面与爆炸的限速步骤的自催化体系的反应¹⁵ NO_广告解离成反应性高的ö_广告和^15个Ñ_广告原子。稳态反应导致形成¹⁵ N ₂，D ₂ O，¹⁵ ND ₃和¹⁵ N ₂O产品。一个加热-冷却循环过程中观察到反应速率的滞后现象可以归因于的累积^15个NO_广告在低温下，然后在T〜490 K的结合能和参与NO + H物种的结构参数表面爆炸通过DFT技术已经计算出在Pd（110）上的₂反应，并且已经考虑了合理的反应途径。从最稳定的短桥位点（E _b  = -1.94 eV）发生的离解是通过具有较低结合能（E _b  = -1.31至1.65 eV）的顶桥和长桥模式的中间体发生的。

气相中过渡态的能量超过NO的能量达到0.2-0.26 eV，这证实了NO分解的限速作用。已经证明OH_广告基团的形成是水分子生成的限速步骤。随后的H ₂ O形成是通过OH _ads中间体的歧化而发生的。
