Major issues in photocatalysis include improving charge carrier separation efficiency at the interface of semiconductor photocatalysts and rationally developing efficient hierarchical heterostructures. Surface continuous growth deposition is used to make hollow Cu2‐xS nanoboxes, and then simple hydrothermal reaction is used to make core‐shell Cu2‐xS@ZnIn2S4 S‐scheme heterojunctions. The photothermal and photocatalytic performance of Cu2‐xS@ZnIn2S4 is improved. In an experimental hydrogen production test, the Cu2‐xS@ZnIn2S4 photocatalyst produces 4653.43 µmol h−1 g−1 of hydrogen, which is 137.6 and 13.8 times higher than pure Cu2‐xS and ZnIn2S4, respectively. Furthermore, the photocatalyst exhibits a high tetracycline degradation efficiency in the water of up to 98.8%. For photocatalytic reactions, the hollow core‐shell configuration gives a large specific surface area and more reactive sites. The photocatalytic response range is broadened, infrared light absorption enhanced, the photothermal effect is outstanding, and the photocatalytic process is promoted. Meanwhile, characterizations, degradation studies, active species trapping investigations, energy band structure analysis, and theoretical calculations all reveal that the S‐scheme heterojunction can efficiently increase photogenerated carrier separation. This research opens up new possibilities for future S‐scheme heterojunction catalyst design and development.

“…3f. The O 1s spectrum in the 525-536 eV range can be divided into four peaks at 531.1, 530.6, 529.9, and 529.4 eV, corresponding to O-C, O=C, In-O-C, and Sb-O-C bonds, respectively [51]. The presence of Sb-O-C and In-O-C bonds indicated that rGO was bonded to both Sb 3+ and In 3+ during the modification growth process, respectively.…”

Antimony selenide (Sb 2 Se 3 ) is a narrow-bandgap semiconductor that has been increasingly used as an excellent light-harvesting material in photoelectrocatalysis. The unique connections of the one-dimensional (Sb 4 Se 6 ) n ribbon structural units determine the high anisotropy of their carrier transport. In this study, a reduced graphene oxide (rGO)modified quasi-one-dimensional Sb 2 Se 3 @In 2 S 3 light-trapping heterostructure was successfully constructed by vapor transport deposition followed by an in situ hydrothermal method. The results showed that the thickness of the in situ grown nonlayered In 2 S 3 nanosheets was significantly reduced from 30 to 10 nm under the space-confinement effect of rGO, facilitating the construction of light-trapping nanostructures and increasing the electrochemically active surface area of the photoelectrode. The quasi-one-dimensional Sb 2 Se 3 @In 2 S 3 -rGO nanorod photoelectrode achieved a higher photocurrent density (1.169 mA cm −2 ), which was 2 and 16 times higher than that of Sb 2 Se 3 @In 2 S 3 and pristine Sb 2 Se 3 , respectively. The ultrathin In 2 S 3 nanosheets were co-modified with rGO nanosheets to fabricate a brush-like composite photoelectrode that exhibited favourable stability with an average hydrogen production rate of 16.59 μmol cm −2 h −1 under neutral conditions. The experimental results and theoretical calculations both showed that the significant improvement in photoelectrochemical performance can be perfectly explained by the type-II heterojunction mechanism. This study provides a new exploration to design rGO-modified composite photoelectrodes for photoelectrochemical applications.

Conversion of light into heat is essential for a broad range of technologies such as solar thermal heating, catalysis and desalination. Three-dimensional (3D) carbon nanomaterial-based aerogels have been shown to hold great promise as photothermal transducer materials. However, until now, their light-to-heat conversion is limited by near-surface absorption, resulting in a strong heat localization only at the illuminated surface region, while most of the aerogel volume remains unused. We present a fabrication concept for highly porous (>99.9%) photothermal hybrid aeromaterials, which enable an ultrarapid and volumetric photothermal response with an enhancement by a factor of around 2.5 compared to the pristine variant. The hybrid aeromaterial is based on strongly light-scattering framework structures composed of interconnected hollow silicon dioxide (SiO 2 ) microtubes, which are functionalized with extremely low amounts (in order of a few μg cm −3 ) of reduced graphene oxide (rGO) nanosheets, acting as photothermal agents. Tailoring the density of rGO within the framework structure enables us to control both light scattering and light absorption and thus the volumetric photothermal response. We further show that by rapid and repeatable gas activation, these transducer materials expand the field of photothermal applications, like untethered light-powered and light-controlled microfluidic pumps and soft pneumatic actuators.
