Replacing fossil fuels with energy sources and carriers that are sustainable, environmentally benign, and affordable is amongst the most pressing challenges for future socio-economic development. To that goal, hydrogen is presumed to be the most promising energy carrier. Electrocatalytic water splitting, if Energy Frontiers: HydrogenIn terms of hydrogen electrocatalysis it can be stated more precisely: at the equilibrium potential the free energy of adsorption of hydrogen from solution should be close to zero. If Sabatier's principle is the only factor that governs a reaction, a plot of the reaction rate versus the free energy of adsorption of the intermediate results in ...
Recent research from our group has shown that an electrocatalysis approach with a CuO electrode can catalyze conversion of glucose to lactic acid, which is considered to be an important organic acid platform chemical.
