Summary: The coupled utilization of solar and thermal energy is a promising strategy for efficient CO2 reduction. In this study, palygorskite clay was used as a silicon source to prepare Co2SiO4 nanosheets, which were then combined with Co3O4 to form a Co2SiO4/Co3O4-x heterojunction. This heterojunction facilitated charge transfer and maintained higher redox potentials, and the cobalt oxide on the surface increased light absorption and produced a local photothermal effect. Under proper thermal activation conditions, photoelectrons captured by oxygen vacancies facilitated electron transfer and suppressed electron-hole recombination, leading to high yields of CH3OH. In situ DRIFTS analysis revealed that the thermal effect facilitated the generation of key intermediate COOH* species. This work demonstrates a new strategy for photothermal catalytic CO2 reduction using natural clay and solar energy.

Summary: This study prepared a nanostructured photocatalyst by assembling perovskite (LaFeO3) on hydrothermal carbonation carbon (HTCC) via a facile microwave hydrothermal method, which was employed to reduce nitrate to ammonia. The nanostructured photocatalyst exhibited a large specific surface area and abundant surface functional groups, promoting nitrate adsorption.

At the optimized mass ratios of pomegranate peel to Fe/La salt, the LaFeO3/HTCC photocatalyst achieved a highest nitrate removal of 94.6% and an ammonia selectivity of 88.7% under visible light irradiation. This work provides a potential approach for the photocatalytic synthesis of ammonia from residual nitrate pollutants.

Summary: This study demonstrates the improvement of mechanical properties and reduction of coefficient of thermal expansion (CTE) in graphene oxide (GO)/epoxy (EP) nanocomposites by enhancing the interface between GO and EP through functionalization and incorporating rigid-flexible interphases. The results reveal that the SiO2-PEA-GO hybrid exhibits better strengthening and toughening effects, as well as lower CTE, compared to the PEA-GO hybrid due to the presence of rigid-flexible interfaces with higher bonding strength and better energy dissipation mechanisms. Additionally, the nanocomposites with longer polyetheramine (PEA) molecules in the rigid-flexible interphases demonstrate higher strength and toughness, while maintaining a lower CTE. This work provides a promising strategy for constructing adjustable flexible-rigid interfacial structures and offers potential in developing GO/EP nanocomposites with high mechanical properties and low CTE.
