(Fig. 25). At the same time, model R43 was synthesized without seleniumsubstituted. The electrocatalytic hydrogen production of four models was studied,
but it was disappointing that although there was an obvious enhanced current in the
catalytic process, it was not homogeneous catalysis. Detection by SEM and EDX, it
was determined that solid particles were continuously deposited on the surface of the
Scheme 9 Mechanism of the R39 catalyzed D 2 /H
+ exchange according to Eq. (5). Reprinted with
