The role of oxygen vacancies in water splitting photoanodes
(Royal Society of Chemistry, 2020-12-01)
Photoelectrochemical water splitting has become one of the most reliable solar-energy conversion
technologies for clean hydrogen production. In the race of developing and understanding new
semiconducting materials for ...
Rational Design of Carbon Nitride Photoelectrodes with High Activity Toward Organic Oxidations
(Wiley, 2022-12-12)
Carbon nitride (CNx) is a light-absorber with excellent performance in photocatalytic suspension systems, but the activity of CNx photoelectrodes has remained low. Here, cyanamide-functionalized CNx (NCNCNx) was co-deposited ...
Direct observation of surface polarization at hybrid perovskite/Au interfaces by dark transient experiments
(American Institute of Physics, 2020-05-05)
A distinctive feature of hybrid perovskite light-absorbing materials is the non-negligible ionic conductivity influencing photovoltaic performance
and stability. Moving ions or vacancies can naturally accumulate at the ...
Catalyst design for highly efficient carbon dioxide hydrogenation to formic acid under buffering conditions
(Elsevier, 2020-03-19)
We report on new ruthenium complexes as catalysts for the efficient transformation of CO2 into formic acid employing basic ionic liquids as buffering media. Remarkably, these complexes catalyze the hydrogenation of CO2 ...
Recent Developments in the Modelling of Heterogeneous Catalysts for CO2 Conversion to Chemicals
(Wiley-VCH Verlag, 2020-04-06)
Density functional theory (DFT) of the CO2 behavior on the catalyst surface provides valuable insights about the C=O bond activation, information about adsorption and dissociation of CO2, understanding the elementary steps ...
Redox‐Active Hybrid Polyoxometalate‐Stabilised Gold Nanoparticles
(Wiley, 2020-08-17)
We report the design and preparation of multifunctional hybrid nanomaterials through the stabilization of gold nanoparticles with thiol‐functionalised hybrid organic–inorganic polyoxometalates (POMs). The covalent attachment ...
A low temperature aqueous formate fuel cell using cobalt hexacyanoferrate as a non-noble metal oxidation catalyst
(Royal Society of Chemistry, 2020-12-01)
Cobalt hexacyanoferrate, the Co–Fe Prussian blue derivative (CoFePB), is an effective, selective and stable electrocatalyst for formate oxidation, exhibiting robust performance under a variety of electrolyte conditions. ...
Characterization of Aerosol Deposited Cesium Lead Tribromide Perovskite Films on Interdigited ITO Electrodes
(John Wiley & Sons, 2021-01-15)
Aerosol deposition (AD) is a promising additive manufacturing method to fabricate low-cost, scalable films at room temperature, but has not been considered for semiconductor processing, so far. The successful preparation ...
Lead Sulfide Nanocubes for Solar Energy Storage
(Wiley, 2020-04-23)
Lead sulfide (PbS) nanocubes are produced by a very simple solvothermal procedure that uses a unique molecule, ethylenediamine, as solvent and capping ligand to control the size and shape of the nanocrystals. Detailed ...
