Abstract

Solar-induced water oxidation reaction (WOR) for oxygen evolution is a critical step in the transformation of Earth's atmosphere from a reducing to an oxidation one during its primordial stages. WOR is also associated with important reduction reactions, such as oxygen reduction reaction (ORR), which leads to the production of hydrogen peroxide (H2O2). These transitions are instrumental in the emergence and evolution of life. In this study, transition metals were loaded onto nitrogen-doped carbon (NDC) prepared under the primitive Earth's atmospheric conditions. These metal-loaded NDC samples were found to catalyze both WOR and ORR under light illumination. The chemical pathways initiated by the pristine and metal-loaded NDC were investigated. This study provides valuable insights into potential mechanisms relevant to the early evolution of our planet.

阐明掺氮碳基光催化剂中的氧进化和还原机制

太阳诱导的氧进化水氧化反应（WOR）是地球大气在原始阶段从还原型向氧化型转变的关键步骤。水氧化反应还与重要的还原反应有关，如氧还原反应（ORR），它导致产生过氧化氢（H2O2）。这些转变对生命的出现和进化至关重要。在这项研究中，过渡金属被负载到在原始地球大气条件下制备的掺氮碳 (NDC) 上。研究发现，这些负载金属的 NDC 样品在光照下可催化 WOR 和 ORR。研究了原始 NDC 和金属负载 NDC 引发的化学途径。这项研究为了解与我们星球早期演化相关的潜在机制提供了宝贵的见解。
