Geobacteracea are distinct for their ability to reduce insoluble oxidants including minerals and electrodes without apparent reliance on soluble extracellular electron transfer (ET) mediators. This property makes them important anode catalysts in new generation microbial fuel cells (MFCs) because it obviates the need to replenish ET mediators otherwise necessary to sustain power. Here we report...

H2 generation from photocatalytic water splitting is one of the most promising approaches to producing cost-effective and sustainable fuel. Nanostructured TiO2 a highly stable efficient semiconductor photocatalyst for this purpose. The main drawback as sluggish charge transfer on surface that can be tackled great extent by use platinum group materials (PGM) co-catalysts. However, scarcity high ...

Nickel is a well-known catalyst in hydrogenation and dehydrogenation reactions. It currently used industrial processes as homogenous heterogeneous catalyst. However, to reduce the cost increase efficiency of catalytic processes, development single-atom catalysts (SACs) seems promising. Some SACs have already shown increased activity stability compared nanoparticle catalysts. From year year, num...
