“…where Q s is the incidence light power (1 sun = 1000 kW m −2 ), Q e is the power of evaporation of the water, m is the mass of evaporated water per unit area, t is time, v is the evaporation rate, and H e is the heat of evaporation of water. 20,43,59 Figure 5A presents the average changing weight curves of bulk water covered by as-prepared PCPs with different concentrations of Py solution (ie, from 0.01M, 0.05M, 0.1M, 0.3M, 0.9M, 1.5M, 3M, to 12M) under simulated sunlight irradiation (1 sun) for 30 minutes. 17 As shown, the water evaporation weight changes from 0.226, 0.311, 0.461, 0.544, 0.532, 0.501, 0.471, to 0.475 kg m −2 when the solution concentration increases from 0.01M to 12M, respectively.…”

“…The efficient collection of solar energy is an essential part of solar steam generation devices. In recent years, benefiting from the exploration of a number of photothermal, including carbon-based materials (carbon black, CNTs, graphene, GO, and rGO), 18 [29][30][31][32][33][34][35] ceramicbased materials (TiN and Ti 3 C 2 ), 8,36 plasmonic metal nanomaterials (Au and Ag,), [37][38][39] and polymer materials (polypyrrole [PPy], polydopamine, poly(1,3,5-hexahydro-1,3,5-triazine), and conjugated microporous polymers), [40][41][42][43][44][45] because of their broadband and high light absorption, great progress has been made in the design and fabrication of high efficiency solar steam generation devices. 46 In general, PPy, as a conjugated conductive polymer, has been explored for many applications, for instance, light-emitting diodes, [47][48][49][50] supercapacitor, 51,52 medical treatment, 53 catalysts, 54 and corrosion protection.…”

Research progress on novel solar steam generation system based on black nanomaterials

“…Single‐layer structures mainly focus on hollow carbon breads, porous graphene sheets, graphene composite aerogels, black polyurethane sponges, Cu 7 S 4 , black titanium, carbon sponges, and polypropylene film . These single‐layer structures can be further summarized into the following two types: one contains suspended particles (Figure a); and the other possesses suspended pore structures (Figure b).…”

Solar-driven steam generation on nitrogen-doped graphene in a 2D water path isolation system

“…New and efficient solar driven steam generation system can drive water evaporating without complex optical concentrator. According to the position of photothermal material placed in liquid medium, evaporation system can be classified into three types, namely volumetric system [19][20][21], interfacial system [8,22,23] and isolation system [14,24,25]. The volumetric system and the interfacial system respectively mean that the solar absorbing material is dispersed inside and on the surface of the bulk working liquid.…”
