1. ( 20 points) There is a great deal of interest in the electrochemical production of H2O2 for which the dominant industrial process involves the metal-catalyzed redox chemistry of alkylanthraquinones. There are two possible routes - oxidation of H2O and reduction of dissolved O2, with the E0 values (from the literature): 2H2OH2O2+2H++2eO2+2H++2eH2O2(E0=1.76Vvs.NHE)(E0=0.67Vvs.NHE) These two reactions together suggest an alternative use of H2O2 in a membrane-free fuel cell that operates by H2O2 reduction at the cathode and oxidation at the anode. (a) (5 points) What would the theoretical potential of such a cell be (answer in Vvs. NHE)? (b) (5 points) What would the overall cell reaction be? (c) (5 points) The literature quotes the half-reaction and E0 value for water oxidation as given above. Something is not quite right with these as stated. Explain. Justify your answer using G0 values and what you know about the thermodynamic stability of H2O2 and H2O. Performance of modulated BDD/Nb to electrochemically generate H2O2 via water oxidation in 1MK2CO3/KHCO3 (salt ratio 1:1,pH9.8, and =188mScm ). (a) Linear sweep voltammograms (LSVs) recorded at a potential range of 1.603.30V vs RHE with a scan rate of 20mVs1. (d) (5 points) Returning to the use of the 2ewater oxidation reaction to generate H2O2, the data shown in the figure above were obtained for a series of B-doped diamond (BDD) catalysts. Which of the 6 BDD catalysts is most effective? State your reasoning based on the data presented in the figure
