Water splitting performance of metal and non-metal-doped transition metal oxide electrocatalysts

Semiconductor Nanomaterial Photocatalysts for Water-Splitting Hydrogen Production: The Holy Grail of Converting Solar Energy to Fuel

“…Positive charge carriers from one photocatalyst are used to oxidize the water, and negative charge carriers from the second photocatalyst are used to reduce the hydrogen ions to hydrogen gas. Semiconductor photocatalysts applied to water should have a small band gap, and water gets simultaneously oxidized and reduced via a two-step water-splitting reaction [ 64 , 76 ], as depicted in Figure 8 .…”

CuCoO2 nanocrystals derived from an isopropanol-modified Cu-BTC using alkaline water oxidation

“…In recent years, hydrogen energy, which has the advantages of zero pollution, zero carbon emission, low molecular weight, highenergy density, abundant reserve and supply, has been known as a viable alternative energy resources. 1,2 In general, electrochemical water splitting is an ideal approach for producing green hydrogen gas without the emission of any polluting gases. 3 Hydrogen production from water electrolysis usually involves two reactions: the cathodic hydrogen evolution reaction (HER) and the anodic oxygen evolution reaction (OER).…”

A transparent iron-incorporated nickel hydroxide electrocatalyst for efficient water oxidation

“…8 In particular, the discovery of electrocatalysts for the OER is of great interest. 9,10 The OER is a challenging reaction that involves a multi-electron transfer and elementary steps besides the requirement for the O-O bond formation. 11,12 It is thus a slow reaction and requires a catalyst to accelerate the reaction process to a kinetically acceptable rate.…”
