Minuscule Amounts of Pt Single Atoms Selectively Loaded on Minor (101) Facet of Anatase Crystallites Enables Outstanding Utilization Efficiency for Photocatalytic H2 Production

open access: yesAdvanced Functional Materials, EarlyView.
Ar–H2 annealing triggers redistribution of pre‐deposited Pt single atoms (SAs) on faceted anatase nanosheets, with selective SAs accumulation on the minor (101) facetsthus the co‐catalytic SA‐sites are positioned only where they are needed, i.e. at the electron exit facets.

Femtosecond pulsed laser deposition of nanostructured TiO2 films in atmosphere

open access: yesAIP Advances, 2017
Nanostructured TiO2 films were grown on a monocrystalline silicon substrate by a femtosecond pulsed laser ablating a Ti target in atmosphere without a vacuum chamber. FESEM and XPS results showed that the TiO2 nanomaterials prepared by this method have a

Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones

open access: yesAdvanced Functional Materials, EarlyView.
Ru‐substituted hexagonal perovskite SrMnO3, featuring face‐shared oxygen species, is designed as an effective heterogeneous catalyst for the aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (>99%) under mild reaction conditions (≥30 °C). Ru substitution promotes oxygen vacancy formation of face‐shared oxygen species

Sono‐Piezo‐Photosynthesis of Ethylene and Acetylene from Bioethanol under Ambient Conditions

open access: yesAdvanced Functional Materials, EarlyView.
A novel sono‐piezo‐photocatalytic strategy enables the conversion of bioethanol to ethylene (C2H4) and acetylene (C2H2) under ambient conditions, addressing the limitations of conventional methods that are high‐temperature and energy‐intensive. By using an advanced graphene oxide/sodium bismuth titanate heterostructure catalyst, this work achieved ...
