This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

New Construction and Catalyst Support Materials for Water Electrolysis at Elevated Temperatures

Nikiforov, Aleksey

DTU Chemistry — 2011

Proton exchange membrane (PEM) water electrolysis presents an attractive technology allowing to produce hydrogen for further use as a renewable energy source in the "Hydrogen cycle". Electrolysis of water steam at elevated temperatures has several advantages over the low temperature process

Development of Refractory Ceramics for The Oxygen Evolution Reaction (OER) Electrocatalyst Support for Water Electrolysis at elevated temperatures

Nikiforov, Aleksey; Prag, Carsten Brorson; Polonsky, J.; Petrushina, Irina; Christensen, Erik; Bjerrum, Niels

E C S Transactions — 2012, Volume 41, Issue 42, pp. 115-124

Commercial TaC and Si3N4 powders were tested as possible electrocatalyst support materials for the Oxygen Evolution Reaction (OER) for PEM water electrolysers, operating at elevated temperatures. TaC and Si3N4 were characterised by thermogravimmetric and differential thermal analysis

Development and Study of Tantalum and Niobium Carbides as Electrocatalyst Supports for the Oxygen Electrode for PEM Water Electrolysis at Elevated Temperatures

Nikiforov, Aleksey; Petrushina, Irina; Prag, Carsten Brorson; Polonsky, J.; Christensen, Erik; Bjerrum, Niels

E C S Transactions — 2013, Volume 45, Issue 21, pp. 59-67

Polymer electrolyte membrane (PEM) water electrolysis is a prospective method of producing hydrogen. We focused on one of its issues – the lack of a suitable support material for the anode electrocatalyst. TaC and NbC were studied as possible electrocatalyst supports for the PEM water electrolysis

Vapor pressure and specific electrical conductivity in the H2O–LiH2PO4–LiPO3 system—a novel electrolyte for water electrolysis at elevated temperature

Berg, Rolf W.; Nikiforov, Aleksey Valerievich; Bjerrum, Niels J.

Ionics — 2021, Volume 27, Issue 2, pp. 703-719

Lithium dihydrogen phosphate, LiH2PO4 (LDP), was studied for water electrolysis at elevated temperatures. It is shown that pure LDP, melting at ~ 224 °C and with correct DSC and X-ray diffraction diagram, in presence of sufficient humidity is stable up to 360 °C. Both solid and liquid LDP
