Bifunctional polypyrrole-based conductive paper towards simultaneous efficient solar-driven water evaporation and electrochemical energy storage

Abstract

The thriving solar-driven water evaporation (SDWE) is considered as the ideal candidate for the next-generation water treatment technology because of its high efficiency, environmental friendliness, and low cost. The irresistible...

Systematic Review of Material and Structural Design in Interfacial Solar Evaporators for Clean Water Production

“…Evaporation rate [kg m À2 h À1 , 1 sun] Energy conversion efficiency (1 sun) ppy/airlaid paper [210] 1.41 81.9% ppy/airlaid paper [212] 1.38 95.33% ppy/origamis paper [211] 2.12 91.5% ppy/filter paper [213] 1.54 ppy/PVDF membrane [225] 1.42 88.7%…”

“…[ 208,209 ] Currently, as shown in Table 7 , the ppy‐based interfacial solar evaporators could be classified into two categories. The first one is directly coating ppy on different kinds of substrates, such as papers, [ 210–213 ] foams, [ 26,214 ] wood, [ 206,215 ] meshes, [ 208 ] and fabric. [ 216 ] The other one is fabricating ppy directly as gels or integrating ppy in the synthesis of porous materials, such as hydrogels, aerogels, and sponges.…”

Mass production of biodegradable porous foam for simultaneous solar evaporation and thermoelectricity generation

“…Photothermal conversion is the most common way to harness solar energy and has been widely used in our lives, including green energy storage and conversion, environmental contaminant removal, and photocatalysis. [1][2][3][4][5][6][7] Water evaporation, which uses solar energy and heat from the environment to change the state of water from liquid to vapor, is ubiquitous in nature. However, due to the large amount of heat loss, the efficiency of volumetric heating is generally low.…”

Reusable Floating Spherical Hydrogel Evaporator for Solar Desalination with Salt Mitigation and Contaminant Elimination

“…Despite remarkable progress on each front, there are some issues that need to be addressed while designing an evaporation material. For instance, the synthesis of photothermal absorbers from sustainable materials or waste material must be emphasized, avoiding the expensive photothermal material and their delicate manufacturing process. − In highly saline water, continuous evaporation of seawater leaves salt crystals deposited on the interfacial evaporator surface, which slowly lowers the performance of the evaporator. ,− Various strategies such as hydrophobic modification of the top surface, − localized crystallization, and combined anionic/cationic polymer networks have been developed to improve the salt-resistance ability . Recently, hydrogel evaporators have emerged as an effective way to reduce salt mitigation.…”
