Perovskites based on earth-abundant elements as robust catalysts for photo-driven oxygen production
The oxygen evolution step is still the bottleneck in the architecture of an artificial photosynthetic system. Nowadays, several catalysts for photo-induced water oxidation have been investigated. However, the challenge consists of designing catalysts that are robust, efficient, and, at the same time, composed of elements that are non-toxic and widely available on the Earth's crust. We prepared a robust and cost-effective catalyst with intriguing performance for oxygen evolution through simple doping. The synthesis, characterisation, and photocatalytic studies on two perovskites based on earth-abundant elements, CaMnO3 and CaMn0.7Fe0.3O3-δ0, are reported. Both perovskites act as productive catalysts for water oxidation, and specifically, doping CaMnO3 oxide with iron increases its photocatalytic activity. Remarkably, as a further advantage, CaMn0.7Fe0.3O3-δ0 appears as a stable compound, which remains unmodified after five consecutive oxygen evolution cycles, thus making it a reusable catalyst for more than one photocatalytic process.
期刊介绍:
Materials Research Bulletin is an international journal reporting high-impact research on processing-structure-property relationships in functional materials and nanomaterials with interesting electronic, magnetic, optical, thermal, mechanical or catalytic properties. Papers purely on thermodynamics or theoretical calculations (e.g., density functional theory) do not fall within the scope of the journal unless they also demonstrate a clear link to physical properties. Topics covered include functional materials (e.g., dielectrics, pyroelectrics, piezoelectrics, ferroelectrics, relaxors, thermoelectrics, etc.); electrochemistry and solid-state ionics (e.g., photovoltaics, batteries, sensors, and fuel cells); nanomaterials, graphene, and nanocomposites; luminescence and photocatalysis; crystal-structure and defect-structure analysis; novel electronics; non-crystalline solids; flexible electronics; protein-material interactions; and polymeric ion-exchange membranes.
