Due to environmental and economic concerns, carbon-free aluminium production has been an ultimate goal for industries. For the past few decades, a considerable amount of research conducted find inert anode material that could replace consumable carbon anodes electrolysis. Anodic materials such as metals, ceramics cermets have studied extensively. All these their advantages disadvantages. Howeve...

The Oxygen Evolving Complex in photosystem II, which is responsible for the oxidation of water to oxygen in plants, algae and cyanobacteria, contains a cluster of one calcium and four manganese atoms. This cluster serves as a model for the splitting of water by energy obtained from sunlight. The recent published data on the mechanism and the structure of photosystem II provide a detailed archit...

A method is reported for the isolation of a highly resolved oxygen-evolving photosystem II reaction center preparation. This preparation can be separated from the more complex photosystem II membranes isolated by the procedure of Berthold et al. [(1981) FEBS Lett. 134, 231-2341 by use of octylglucopyranoside at elevated ionic strengths; the oxygen-evolving material can be collected by centrifug...

Manganese oxides have been extensively investigated as model systems for the oxygen-evolving complex of photosystem II. However, most bioinspired catalysts are inefficient at neutral pH and functional similarity to the oxygen-evolving complex has been rarely achieved with manganese. Here we report the regulation of proton-coupled electron transfer involved in water oxidation by manganese oxides...
