It's really a toss-up between it and the Hydrogen, but you can just ignore the Oxygen off the top, since it is by itself on one side, making it easy to fix at the end. Since you have minimum 6 Carbons on the right, you need at least 6 CO2 to balance the Carbon, as CO2 has only 1 each. 6CO2 + H2O -----> C6H12O6 + O2 The Carbon is balanced, so let's try to balance the Hydrogen now. Since there are 12 Hydrogens on the right, we need 6 H2O to balance, as there are 2 Hydrogens in each. 6CO2 + 6H2O -----> C6H12O6 + O2 Checking both sides again, we see that both sides have the same number of Carbon and Hydrogen, so now let's look at the Oxygen. Counting the left side, we see that there are 6(2) + 6 = 18 Oxygen. However, the right side only has 6 + 2 = 8 Oxygen. Fortunately, the difference of 10 is an even number, so all we need to do is increase the coefficient for O2 until we get 18 on the right side. Since each additional O2 provides 2 additional Oxygen, we will need 10/2=5 ADDITIONAL O2. The new coefficient should be 6, giving: 6CO2+6H2O -----> C6H12O6 + 6O2 Checking both sides, we now see that it is balancedSuggest Corrections0 Access through your institutionHighlights•CeO2/Co(OH)2 hybrid electrocatalyst was synthesized for oxygen/hydrogen evolution reactions.•The high electocatalytic activity is originated from unique interface between CeO2 and Co(OH)2.•Superior oxygen/hydrogen evolution performances were evaluated with long-term catalyst has been intensively studied over the past decades due to its advantages in many applications. It has been shown that CeO2 nanoplates with an average diameter of nm have uniform contact with Co(OH)2. The objective of the present study was to comprehensively investigate CeO2/Co(OH)2 hybrid catalysts using various structural and electrochemical analysis to understand the synergetic effect between CeO2 and Co(OH)2 beneficial interaction on oxygen evolution and hydrogen evolution reaction (OER and HER) characteristics. OER/HER results showed excellent catalytic activity of CeO2/Co(OH)2 hybrid catalysts with an overpotential of 410 (OER) and 317 mV (HER) compared to pure CeO2 nanoplates and Co(OH)2 powder. Corresponding Tafel slopes of CeO2/Co(OH)2 hybrid catalysts for OER and HER were 66 and 140 mV dec−1, respectively, lower than those of evaluated CeO2 nanoplates and Co(OH)2 powder. Compared to bare CeO2 nanoplates and Co(OH)2, CeO2/Co(OH)2 hybrid catalysts exhibited remarkably enhanced electrocatalytic activity for OER and catalystOxygen evolution reactionHydrogen evolution reactionCited by (0)View full text© 2019 Elsevier All rights reserved.
