What are the different types of photothermal nanomaterials?

Different types of photothermal nanomaterials, including carbon-based nanomaterials (graphene oxide, CNTs), (811,814,815) MXene nanosheets, (813,816−818) metal nanoparticles, (810,819) and organic polymers, (820−822) have been successfully combined with phase-change materials to achieve high photothermal energy conversion efficiencies.

What are nanostructured photothermal materials?

We present an extensive catalogue of nanostructured photothermal materials, including metallic/semiconductor structures, carbon materials, organic polymers, and two-dimensional materials. The proper material selection and rational structural design for improving the photothermal performance are then discussed.

What are the applications of photothermal materials?

The investigation of photothermal materials with broadband absorption is beneficial for the utilization of renewable solar energy, while the engineering of materials with efficient heat generation abilities can be widely useful in various fields, including water evaporation, (6,7) photothermal catalysis, (8,9) and biomedicine.

How a photothermal material converts light into heat?

2.4.3. Heat Transfer After the incident light is absorbed by a photothermal material, the photon energy is converted into thermal energy through a light-to-heat conversion process. The generated heat will be further transferred to other lower-temperature materials or released to the surrounding environment.

Are photothermal nanomaterials powerful light-to-heat converters?

Herein we review the latest progresses on photothermal nanomaterials, with a focus on their underlying mechanisms as powerful light-to-heat converters. We present an extensive catalogue of nanostructured photothermal materials, including metallic/semiconductor structures, carbon materials, organic polymers, and two-dimensional materials.

What are the advantages of photothermal nanomaterials?

One major advantage of photothermal nanomaterials is their broad light absorption range and excellent photothermal conversion ability, thus allowing for the efficient utilization of solar energy as a sustainable solution for energy scarcity.
