CoHPi Nanoflakes for Enhanced Oxygen Evolution Reaction
ACS Applied Materials & Interfaces, 2018Electrochemical splitting of water to produce hydrogen and oxygen is an important process for many energy storage and conversion devices. Developing efficient, robust, low-cost, and earth-abundant electrocatalysts for the oxygen evolution reaction (OER) is therefore of great importance. Herein, we report a novel method to prepare two-dimensional cobalt

Measuring oxygen reduction/evolution reactions on the nanoscale
Nature Chemistry, 2011The efficiency of fuel cells and metal-air batteries is significantly limited by the activation of oxygen reduction and evolution reactions. Despite the well-recognized role of oxygen reaction kinetics on the viability of energy technologies, the governing mechanisms remain elusive and until now have been addressable only by macroscopic studies.

Orbital Physics of Perovskites for the Oxygen Evolution Reaction
Topics in Catalysis, 2018The study of magnetic perovskite oxides has led to novel and very active compounds for O2 generation and other energy applications. Focusing on three different case studies, we summarise the bulk electronic and magnetic properties that initially serve to classify active perovskite catalysts for the oxygen evolution reaction (OER).

Evaluation of Perovskites as Electrocatalysts for the Oxygen Evolution Reaction
ChemPhysChem, 2014AbstractThe oxygen evolution reaction (OER) is an enabling process for technologies in the area of energy conversion and storage, but its slow kinetics limits its efficiency. We performed an electrochemical evaluation of 14 different perovskites of variable composition and stoichiometry as OER electrocatalysts in alkaline media. We particularly focused

Oxygenated Carbon Electrocatalysts for Chlorine Evolution Reaction
Journal of the American Chemical SocietyThe chlor-alkali process plays an irreplaceable role in global chemical industry, but relies heavily on RuO2 (or IrO2)/TiO2-based dimensionally stable anodes, hindering sustainability and new applications. We report a facile oxygenation activation approach to create apt oxygen groups on commercial carbon black and carbon cloth.
