电催化反应的最新趋势之一涉及氧还原反应（ORR），其中已经形成了一种新的范例来利用该反应来合成过氧化氢（H2O2）。 H2O2 是一种用途广泛的化学品，具有很高的商业价值，目前通过可持续的工艺制备。用于选择性合成 H2O2 的无金属碳催化剂的出现预计将彻底改变 ORR 研究，吸引新工业方案的开发。通过理论和实验研究的结合，揭示了该机制的复杂性和主导该过程选择性的因素。
One of the recent trends in electrocatalytic reactions involves the oxygen reduction reaction (ORR), where a new paradigm has been shaped to exploit this reaction for the synthesis of hydrogen peroxide (H2O2). H2O2 is a very versatile chemical of high commercial value, prepared currently through poorly sustainable processes. The emergence of metal-free carbon catalysts for the selective synthesis of H2O2 is expected to revolutionize ORR research, beckoning at the development of new industrial schemes. The complexities of the mechanism and the factors dominating the selectivity of the process have been unveiled through a combination of theoretical and experimental studies.
