Enhanced photoproduction of hydrogen on Pd/TiO2 prepared by mechanochemistry
(Elsevier, 2022-07-15)
Article
Open AccessSupported metal clusters are considered as promising cocatalysts in heterogeneous photocatalysis due to their singular geometric structures and unique reactivity. Nevertheless, to explore efficient synthetic routes that ... -
Au/TiO2 2D-photonic crystals as UV–visible photocatalysts for H2 production
(2022-02-10)
Article
Restricted access - publisher's policyNoble metal decoration of wideband gap semiconductors enables the excitation of surface plasmons in the visible range that upon relaxation generate hot carriers used for catalysis. However, this strategy leads to photocatalytic ... -
Ultradispersed Mo/TiO2 catalysts for CO2 hydrogenation to methanol
(Royal Society of Chemistry (RSC), 2021-09-21)
Article
Restricted access - publisher's policyMo/TiO2 catalysts with atomic dispersion of molybdenum appear active and stable in the gas-phase hydrogenation of CO2. A comparison between various titania materials shows a crucial effect of the support surface structure ... -
Preparation of SBA-15 and Zr-SBA-15 materials by direct-synthesis and pH-adjustment methods
(2021-10-15)
Article
Restricted access - publisher's policySBA-15 mesoporous silica materials with zirconium atoms incorporated into its structure were prepared by two methods: direct-synthesis and pH-adjustment. Two nominal ratios of Zr/Si = 0 and 0.10 were evaluated. N2-physisorption, ... -
Ligand conversion in nanocrystal synthesis: the oxidation of alkylamines to fatty acids by nitrate
(American Chemical Society (ACS), 2021-11-22)
Article
Open AccessLigands are a fundamental part of nanocrystals. They control and direct nanocrystal syntheses and provide colloidal stability. Bound ligands also affect the nanocrystals’ chemical reactivity and electronic structure. Surface ... -

X-ray photoelectron and Raman spectroscopy of nanostructured ceria in soot oxidation under operando conditions
(2021-06)
Article
Restricted access - publisher's policyCeria nanoshapes exhibiting different amounts of {100}, {110} and {111} facets (cubes, rods, octahedra and polyhedra) were prepared, characterized, tested in the carbon soot oxidation reaction, and studied by operando near ... -
Review of the Decomposition of Ammonia to Generate Hydrogen
(American Chemical Society (ACS), 2021-05-21)
Article
Open AccessBecause of the problems associated with the generation and storage of hydrogen in portable applications, the use of ammonia has been proposed for on-site production of hydrogen through ammonia decomposition. First, an ... -
Molecular engineering to tune the ligand environment of atomically dispersed nickel for efficient alcohol electrochemical oxidation
(2021-09-16)
Article
Open AccessAtomically dispersed metals maximize the number of catalytic sites and enhance their activity. However, their challenging synthesis and characterization strongly complicates their optimization. Here, the aim is to demonstrate ...
