Bioinspired Soot‐Deposited Janus Fabrics for Sustainable Solar Steam Generation with Salt‐Rejection

“…So it is urgent to search for new methods to solve this problem. A possible solution requires the use of abundant solar energy to produce heat for vapor generation . In that case, the water can get energy from sun to vaporize and thus realize the purification of wastewater or sea in an easy and cheap way.…”

Solar‐Inspired Water Purification Based on Emerging 2D Materials: Status and Challenges

“…In this part, we mainly summarize the recent development of 2D materials for enhancing the absorption and PTCE. The specific strategies for strong absorption mainly includes hybrid design, phase transition, defect modulation, combination of plasmonic and all‐dielectric properties, and introduction of intermediate band (IB) states in alloying materials . To convert the light energy to heat efficiently, the high PTCE of 2D materials is needed.…”

“…Then, the hot electrons interact with crystal lattice and new phonons are emitted (Step IV). BiInSe 3 shows efficient photothermal conversion because of its abundant IB states and is thus chosen for building evaporation systems . Therefore, the BiInSe 3 ‐based solar evaporation system can realize a high water evaporation rate of 0.83 kg m −2 h −1 upon 1 sun irradiation.…”

“…Carbon foam (CF) can also be selected as a heat barrier and supporting material because of the low thermal conductivity and light weight. By collaborating with photothermal agent of BiInSe3, high evaporation rate of 1.1 kg m −2 h −1 upon 1 sun irradiation can be obtained . The porous structure of CF can allow the water supply from bulk water to the heat production center and in the meantime can efficiently block the heat loss from heat production point to bulk water.…”

Efficient Self‐Driven Photodetectors Featuring a Mixed‐Dimensional van der Waals Heterojunction Formed from a CdS Nanowire and a MoTe2 Flake

“…Several 2D layered materials, including graphene, hexagonal boron nitride, black phosphorus, transition metal dichalcogenides (TMDs), and post‐transition metal dichalcogenides, are receiving widespread attention for their exceptional structures and fascinating physical and chemical properties . Specifically, the high mechanical strength, piezoelectric phenomena, and thickness‐dependent electronic band structures of 2D layered materials have led to their use in several prototypical applications, including field effect transistors (FETs), phototransistors, biosensors, piezotronic devices, photothermal conversion, and catalysts …”
