C02 Hydrogenation on Pd

C02 hydrogenation on Pd was investigated29 under atmospheric pressure and at temperatures 540°C to 605°C. The CO formation rate (reverse water-gas shift reaction) exhibits purely electrophilic behaviour with a rate increase by up to 600% with increasing sodium coverage (Fig. 9.20). This purely electrophilic behaviour is consistent with low reactant coverages and enhanced electron acceptor C02 adsorption on the Pd surface with increasing sodium coverage (Rule G2). 

C2H2 to C2H4. Both studies are noteworthy in that f3 -Al203 has been used as the solid electrolyte at temperatures as low as 70 - 100°C. 

The decomposition of NH3 has been investigated on Fe films deposited on K2YZr(P04)3, a K+ conductor,32 and on CaZr0.9lno.i03-a, a H+ conductor,32,33 at temperatures near 500°C. In both cases electrophobic behaviour was observed with p values up to 5 and A values, for the case of the H+ conductor, up to 120.33
