Effectively harnessing renewable and inexhaustible solar radiation for energy conversion has attracted significant research interest in the past decade. Solar thermal conversion, as a ubiquitous phenomenon, can be implemented to evaporate water and concurrently boost photocatalytic performance for addressing freshwater scarcity and energy crisis. Most recently, solar water evaporation accompanied by photocatalytic degradation, sterilization, and hydrogen production has been proposed as a promising avenue to endow new vitality into the field of clean water and energy production. Driven by the advances of rationally designed solar-powered functional materials, a large variety of photothermal-coupled photocatalysis technologies have been exploited. In this context, it is imperative to summarize the recent progress and discuss the challenges in this multidisciplinary field. Herein, we overview photothermal materials based on various fundamental principles and highlight emerging applications in the areas of solar water evaporation, water purification, and solar-driven energy production. Furthermore, the challenges and perspectives toward both fundamental research and practical applications are also proposed. It is envisioned that this review can provide insightful suggestions to further advance the development of integrated solar thermal driven water evaporation and photocatalytic systems to fulfill concurrent energy conversion and environmental applications.

• A composite photocatalyst of Ag 3 PO 4 particles decorated on modified crispy g-C 3 N 4 flake was fabricated. • Photocatalytic oxygen evolution over Z-scheme heterojunction is roughly 7-fold higher than that in Ag 3 PO 4. • Highly efficient oxygen-evolving performance is mainly attributed to accelerated interfacial charge transfer. • Surface modification and nitrogen atmosphere favor well-organized g-C 3 N 4 nanostructures and enhanced photocatalytic activity. Searching for highly efficient photocatalysts for water oxidation is the footstone for the development of overall water splitting systems and has been actively pursued. The construction of artificial Z-scheme heterojunction photocatalysts has been conclusively proven to be effective in boosting charge transport property and in improving the OER performance. Herein, Ag 3 PO 4 particles anchored on modified crispy g-C 3 N 4 flakes have been successfully fabricated. KOH-assisted surface modification of g-C 3 N 4 flakes and intimate interfacial contact favor the accelerated charge transfer and highly improved OER efficiency. Ultrafast spectroscopy results reveal that modified g-C 3 N 4 with crispy nanostructures possesses more trap-induced long-lived photogenerated holes, which are extremely helpful to combine with photo-generated electrons from the conduction band (CB) position of Ag 3 PO 4 via the specific Z-scheme configuration, leaving more holes in the valence band (VB) of Ag 3 PO 4 for the enhanced OER. Superb oxygen-evolving performance highlight the great promise of Z-scheme Ag 3 PO 4 -based heterojunctions in solar-driven photocatalytic water splitting. [ABSTRACT FROM AUTHOR]

• 1D CdS/2D Ti3C2 MXene Schottky heterojunction was successfully fabricated. • In situ constructed Schottky photocatalyst exhibits enhanced HER performance. • Ultrathin 2D MXene enhances light absorption and accelerates charge transport. • The specific Schottky interface is responsible for the improved HER activity. Benefiting from excellent metallic conductivity, full-spectrum solar energy absorption and rich active sites on the surface, atomically thin two-dimensional transition metal carbide (2D MXene) shows great promise in improving solar-to-hydrogen efficiency and has drawn intense interest in the field of photocatalysis. However, controllable construction of ultrathin 2D MXene-based heterojunction photocatalysts still remains a significant challenge. Herein, one-dimensional (1D) CdS nanorod/2D MXene nanosheet heterojunctions with well-defined nanostructures and strong interfacial coupling are fabricated by in situ assembling solvothermally-generated CdS nanorods on ultrathin Ti 3 C 2 MXene nanosheets. Due to their specific interface characteristics, 1D/2D Schottky heterojunction is capable of providing accelerated charge separation and a lower Schottky barrier for solar-driven hydrogen evolution from water splitting. As expected, the Schottky-based photocatalyst is 7-fold more active in the illuminated hydrogen evolution reaction (HER) than pristine CdS nanorods, implying the synergistic effects between n-type semiconductor CdS and highly conductive 2D Ti 3 C 2 MXene nanosheets.

The first-line treatment of cerebral venous sinus thrombosis (CVST) is systemic anticoagulation. However, patients with severe or a clinically worsening condition might benefit from mechanical thrombectomy (MT) combined with intraoperative thrombolysis (IOT) or MT with continuous thrombolytic infusion (CTI). The present study compared the efficacy and safety of these 2 endovascular therapeutic methods by performing a systematic review of the literature. The present systematic review was conducted to identify all cases of CVST treated with MT+IOT or MT+CTI/MT+IOT+CTI reported in PubMed and Ovid. The recanalization rates, outcomes, operation-related complications, sequelae, and postoperative hemorrhage rates were evaluated. A total of 28 studies, including 82 patients, met the inclusion criteria. Alone, MT+IOT was performed in 42 patients (51%), and MT+CTI/MT+IOT+CTI was performed in 40 patients (49%). Overall, outcomes data were available for 69 patients, of whom 57 (82%) had had a good outcome and 12 (18%) had had a poor outcome or had died. Recanalization data were available for 68 patients. Of these patients, 28 (41%) had had complete recanalization, 40 (59%) had had partial, and no patient had had no recanalization. Operation-related complications occurred in 5 patients (6%), and 3 patients (4%) developed postoperative intracerebral hemorrhage. However, no significant differences were found in the recanalization rate or prognosis between the MT+IOT and MT+CTI/MT+IOT+CTI groups. The results from our review suggest that MT with local thrombolysis is relatively safe, with no significant differences in efficacy and safety between MT+IOT alone and MT+CTI/MT+IOT+CTI. However, randomized controlled studies are required to provide a definitive answer on its use for CVST. [ABSTRACT FROM AUTHOR]

Most birds build nests to incubate their eggs and raise their young in a protective environment. In their Communication on page 11265 ff., J. Pérez‐Ramírez, N. López et al. apply a nesting concept to anchor isolated palladium atoms within the cavities of graphitic carbon nitride. This leads to a stable single‐site heterogeneous catalyst with outstanding performance in hydrogenation reactions (artwork concept: Amalia Gallardo, illustration: Marcel Reich).

Viele Vögel bauen Nester …︁ …︁, um ihre Eier auszubrüten und ihre Jungen in geschützter Umgebung großzuziehen. In ihrer Zuschrift auf S. 11417 ff. verwenden J. Pérez ‐ Ramírez, N. López et al. ein “Nestbau ‐ Konzept” für die Einlagerung isolierter Palladiumatome in den Poren von graphitischem Kohlenstoffnitrid. Dies führt zu einem hervorragenden heterogenen “Single ‐ Site” ‐ Katalysator für Hydrierungsreaktionen (Titelbildkonzept: Amalia Gallardo, Illustration: Marcel Reich). [ABSTRACT FROM AUTHOR]
