Recent Findings in Nanoporous Described by S.X. Zhuang and Colleagues

  2012 MAY 14 - (VerticalNews.com) -- According to the authors of a study from Changsha, People's Republic of China, "Perovskite-type series of La1-xCaxCoO3 compounds were synthesized by a modified amorphous citrate precursor method. Their catalytic activities for hydrogen peroxide electroreduction in 3.0 mol dm(-3) KOH at 25 degrees C were evaluated by cyclic voltammetry and galvanostatic measurement."

  "The influence of x in La1-xCaxCoO3 on their catalytic performance was investigated. Among these compounds, La0.6Ca0.4CoO3 calcined at 650 degrees C exhibited the highest catalytic activity," wrote S.X. Zhuang and colleagues.

  The researchers concluded: "An aluminum-hydrogen peroxide cell containing 0.4 mol dm(-3) H2O2 as oxidant and using La0.6Ca0.4CoO3 as cathode catalyst achieved a peak power density of 201 mW cm(-2) at 150 mA cm(-2)."

  Zhuang and colleagues published their study in International Journal of Electrochemical Science (Electrocatalytic Activity of Nanoporous Perovskite La1-xCaxCoO3 Towards Hydrogen Peroxide Reduction in Alkaline Medium. International Journal of Electrochemical Science, 2012;7(1):338-344).
