Z scheme diagram

Figure 22 The energy level diagram (Z-scheme) for photocatalytic water decomposition by a tandem cell.

The pathway of electron flow is called the Z scheme of photosynthesis because the diagram from p680 to p700 resembles the letter Z (Figure 7.10) [37,39].

Figure 3.8 Typical kinetic curves (A, C, E) and the corresponding phase trajectories (B, D, F) of the evolution of thermodynamic rushes of intermediates Y (solid line) and Z (dash line) in scheme (3.35) with damped oscillations. Calculations are given for the cases of constant values Sq = 2, S2 = 0.5, and S3 = 5 and starting condition Ya =2, Za = t at different values of the controlling parameters R R = 1 in diagrams A and B (stationary state at Y = 10.4, Z = 0.4) R = 30 in diagrams C and D (stationary state at Y — 22, Z — 12), and R = 50 in diagrams E and F (stationary state Y = 30, Z — 20). There is a bifurcation value of the controlling parameter R = 25 for all the other external parameters.
