Summary: Bulk nanostructuring has been a leading strategy for optimizing thermoelectric properties by introducing strong grain boundary scattering, but recent findings have shown that charge carrier transport in some nanostructured materials can be significantly suppressed. Understanding the interaction mechanism of grain boundaries on carrier transport and strategies to enhance thermoelectric performance are crucial. Additionally, using the charge shielding ratio as an indicator to distinguish between different scattering mechanisms is proposed.

Summary: Solar-driven elimination of refractory contaminants is an ideal approach for environmental remediation. However, the photocatalytic performance of photocatalysts is limited by insufficient reactive sites and fast recombination of electrons and holes. In this study, a novel metal-organic framework-based heterostructure of MIL-101(Fe)/Bi2WO6 was synthesized, which exhibited significantly enhanced photoactivity for Cr(VI) reduction and tetracycline hydrochloride oxidation compared to individual Bi2WO6 and MIL-101(Fe). The improved catalytic performance can be attributed to the enlarged surface area and pollutant adsorption facilitated by MIL-101(Fe), as well as the efficient photo-carrier transport mechanism supported by oxygen vacancies.
