Temkin-Boudart mechanism

Regarding the participation of intermediate in the steps of detailed mechanism, Temkin (1963) classified catalytic reaction mechanisms as linear and non-linear ones. For linear mechanisms, every reaction involves the participation of only one molecule of the intermediate substance. The typical linear mechanism is the two-step catalytic scheme (Temkin-Boudart mechanism), e.g. water-gas shift... 

Graphs of the two-step one-route mechanisms (the Temkin-Boudart mechanisms) for the steam conversion of CO and liquid-phase hydrogenation are illustrated in Fig. 3(b) and (c)... 

In heterogeneous catalysis, the simplest mechanism of a catalytic cycle is the two-step Temkin-Boudart mechanism. A particular case of this mechanism is the two-step mechanism of the water-gas shift (WGS) reaction (see Table 3.3). Table 3.4 shows a general representation of the... 

Temkin-Boudart mechanism. Catalytic intermediate Z is consumed in the first reaction and produced in the second one, while intermediate AZ (or OZ in the WGS mechanism) is produced in the first reaction and consumed in the second. Multiplying these reactions by the corresponding Horiuti numbers o, which here equal one, and adding them, yields the overall reaction. 

The steady-state kinetic model of the general Temkin-Boudart mechanism is written in accordance with the mass-action law as... 

The simplest catalytic reaction mechanism is the Temkin-Boudart mechanism, which is a single-route mechanism consisting of two reversible steps...
