The construction of photocatalytic systems that have strong redox capability, effective charge separation, and large reactive surfaces is of great scientific and practical interest. Herein, an edge‐connected 2D/2D Z‐scheme system that combines the facet junction and the interfacial heterojunction to achieve effective long‐range charge separation and large reactive surface exposure is designed and fabricated. The heterostructure is realized by the selective growth of 2D‐layered MoS2 nanoflakes on the edge‐sites of thin TiO2 nanosheets via an Au‐promoted photodeposition method. Attributed to the synergetic coupling of the facet junction and the interfacial heterojunction that assures the effective charge separation, and the tremendous but physically separated reactive sites offered by layered MoS2 and highly‐exposed (001) facets of TiO2, respectively, the artificial Z‐scheme exhibits excellent photocatalytic performance in photodegradation tests. Moreover, the junctional plasmonic Au nanoclusters not only act as electron traps to promote the edge‐selective synthesis but also generate "hot electrons" to further boost photocatalytic performance. The Z‐scheme charge‐flow direction in the heterostructure and the roles of electrons and holes are comprehensively studied using in situ irradiated X‐ray photoelectron spectroscopy and photodegradation tests. This work offers a new insight into designing high‐performance Z‐scheme photocatalytic systems. [ABSTRACT FROM AUTHOR]

The crucial role of capillary pumping has motivated recent innovations in porous wicking materials for many energy and environment applications. Herein, the wick‐based liquid propagation along with a porous surface, including both macroscopic water transport behavior and microscopic wicking dynamics, with a group of nanostructured porous surfaces, is investigated. These hybrid wicking surfaces are fabricated in a scalable way by bonding copper micromeshes on flat surfaces and chemical etching. These nanostructured porous surfaces exhibit outstanding wickability by simultaneously improving surface hydrophilicity and minimizing viscous dissipation of water flow. Notably, the as‐fabricated surfaces also have good thermal conductivity and high solar absorptance, which are desired properties for various solar thermal applications. To directly observe water propagation processes, infrared thermal imaging in locating the propagation front and evaluating water film thickness along the propagation direction is also demonstrated. The dynamic water vapor meniscus in a representative pore unit is captured and characterized through environmental scanning electron microscopy. A capillary pressure model and permeability model to predict the liquid propagation and wicking characteristics is then developed, resulting in good agreement with experimental results for a large variety of nanostructured porous surfaces.
