A New Method for the Preparation of Monoporous Hollow Microspheres

Langmuir, 2010
The feasibility of producing a hollow microsphere with a single hole in its shell by coaxial electrohydrodynamic atomization (CEHDA) is demonstrated. Polymethylsilsesquioxane (PMSQ) was used as a model shell material encapsulating a core of a volatile liquid, perfluorohexane (PFH), which was subsequently evaporated to produce the hollow microspheres ...

Metal‐Organic Framework‐Templated Construction of Internal Electric Field and S‐Vacancy Defect‐Engineered S‐Scheme Heterojunction for Enhanced Photocatalytic Hydrogen Evolution

EcoEnergy, EarlyView.
A Bi2S3@ZnIn2S4 heterojunction with abundant sulfur vacancies was fabricated through MOF‐templated in situ synthesis. DFT calculations and experiments confirm the presence of an internal electric field (IEF) and S‐scheme charge transfer. The optimized catalyst shows a superior H2 evolution rate of 5.13 mmol·h−1 g−1 under visible light, which is 11.7 ...
