Density functional theory is utilized to articulate a particular generic deconstruction of the electrode/electro-catalyst assembly for the cathode process during water splitting. A computational model was designed to determine how alloying elements control the fraction of H2 released during zirconium oxidation by water relative to the amount of hydrogen picked up by the corroding alloy. This mo...

Characteristics of nanosized Pt electro-catalyst deposited on carbon nanotubes (CNTs) were studied with CO-stripping voltammogram and chronoamperometry measurements. The CNTs were pretreated by oxidation in HNO3, mixed HNO3 + H2SO4 and H2SO4 + K2Cr2O7 solution, respectively, to enable surface modification. Well-homogenized Pt particles (average size: 3 nm) were loaded onto the pretreated CNT sa...

Nickel-manganese oxides with variable Ni : Mn ratios, synthesised from heterobimetallic single-source precursors, turned out to be efficient water oxidation catalysts. They were subjected to oxidant-driven, photo- and electro-catalytic water oxidation showing superior activity and remarkable stability. In addition, a structure-activity relation could be established.

Novel concave gold nanocuboids bounded by 24 high-index {611} facets are synthesized using the seed-mediated growth method via an overgrowth mechanism. The as-synthesized products demonstrated greatly enhanced catalytic activity for the electro-oxidation of glucose and the reduction of 4-nitrothiophenol (4-NTP) under a laser.

A cobalt-based molecular catalyst was successfully grafted to a fullerene derivative via 'click' chemistry on an electrode for both electro-catalytic and light driven water reduction. Using an organic photovoltaic electrode immobilized with a cobalt catalyst as the photocathode, the photoelectrochemical cell displayed a stable photocurrent.
