Molecular Foundry researchers have developed a method to create and control mesoporous architecture in metal chalcogenides (a class of semiconductors used in light- and energy-harvesting devices) that was maintained during reversible chemical transformations.
Significance and Impact
Mesoporous architecture enables new functionalities in metal chalcogenides by creating large internal surface area and an interconnected network of pores, which is promising for applications in chemical sensing, nanoionics and photocatalysis.
- Metal chalcogenides are important materials for a myriad of devices, but the ability to control their porosity is lacking.
- The researchers induced hierarchically ordered porosity using surface-treated nanocrystals and complementary architecture
- The resulting mesoporous materials are robust to thermal annealing and chemical transformations.
