Silver sulfide decorated carbonaceous sawdust/ES-PANI composites as salt-resistant solar steam generator

Abstract

Solar steam generation (SSG) is a potential approach for resolving the global water and energy crisis while causing the least amount of environmental damage.

Hydrothermally Derived Hydrochar from Waste Sawdust for Solar Vapor Generation

“…[20,24] The average efficiency and evaporation rate of the solar absorber were compared to preceding studies. Sadoun et al [41] used carbonized sawdust-based composite as solar absorber, where the efficiency and evaporation rate of the solar absorber was at 91.5% and 1.1 kg m À2 h À1 , respectively, when tested under simulated light at 1 sun using water. The efficiency of the carbonized sawdust-based solar absorber by Saad et al [16] and Wu et al [17] was about 90.4% and 91.5%, respectively, when tested under simulated light with intensity of 1 sun using water.…”

A durable hydrophobic photothermal membrane based on a honeycomb structure MXene for stable and efficient solar desalination

“…For example, Ibrahim et al reported a carbonaceous sawdust/ES-PANI composite decorated with silver sulfide, which enabled a clear salt-rejection capability. 23 Chen and co-workers employed the tetrapyridylporphyrin as an interface in water evaporation with a water evaporation rate of 0.69 kg m −2 h −1 and a stable voltage up to 60 mV. 24 Furthermore, laser-treated wood and carbonized pine cone were chosen as photothermal materials due to their high conversion efficiency and evaporation flux reported by Wang et al 25 and Goharshadi et al 26 Although diverse approaches have been employed to improve the light-to-heat conversion efficiency, in practice, the overall steam production capability and water production capacity still have a lot of room for improvement.…”

Stable polyethylene glycol/biochar composite as a cost-effective photothermal absorber for 24 hours of steam and electricity cogeneration

“…43 Pyrolysis at low temperatures is recommended to increase the efficiency of solar steam generation (SSG) because it maintains the abundant microchannels across the sugarcane bagasse structure, which increases the ow of water to the evaporator surface and helps to improve light scattering. 17,44 Moreover, the microchannels of the biochar structure can allow the salt to return to the water improving the salt rejection ability. 45 The additional advantage is the existence of different functional groups that have a high affinity for heavy metals and prevent salt formation on the surface.…”
