Highly efficient solar evaporator based on Graphene/MoO3-x coated porous nickel for water purification

Heteropoly Blue/Carbon Nanotubes Nanocomposites as High‐Performance Photothermal Conversion Materials

“…Among them, the solar water evaporator constructed based on HPB/CNTs (20 %) thin film can achieve a water evaporation rate of 2.04 kg m À 2 h À 1 , which is up to 1.86 kg m À 2 h À 1 after deducting the natural evaporation rate of water under dark field conditions (0.18 kg m À 2 h À 1 ), which is approximately 6 times higher than that of water without evaporator conditions (0.31 kg m À 2 h À 1 ) and has the highest evaporation rate among the solar evaporators based on POMs or molybdenum oxides that have been reported so far. [25][26][27][28][29] The SVG behavior of the HPB/CNTs (20 %) films is further evaluated at different irradiation intensities, and after deducting the dark field evaporation, the evaporation rate is 0.71 kg m À 2 h À 1 at 0.5 sun (0.5 kW m À 2 ), about 7.1 times that of water (0.10 kg m À 2 h À 1 ), and 3.34 kg m À 2 h À 1 at 2 sun (2 kW m À 2 ), which is about 6.3 times that of water (0.53 kg m À 2 h À 1 ) (Figure 5d and Figure S7).…”

Recent advances and challenges of emerging solar-driven steam and the contribution of photocatalytic effect

“…In the indirect contact mode, the photoabsorber is supported on a thermal insulator to avoid heat transfer and promote the heat localization at the evaporative surface (Figure 2c). Unlike contact mode, the heat loss can be limited in indirect contact mode, wherein the top evaporative surface is separated from bulk water using an insulator [35,36]. This system involves a water pumping process and hydrophilic solar lightabsorbing materials (photothermal material).…”

Development of defective molybdenum oxides for photocatalysis, thermal catalysis, and photothermal catalysis

“…15d). 120 In addition, due to the growing problem of water pollution, the development of adequate catalysts for water disinfection technologies is critical for public health. Niu et al recently synthesized a composite material (H x MoO 3− y /NCNs) with near-infrared (NIR) light-triggered thermosensitive properties capable of efficiently disinfecting water, including the elimination of Enterobacteriaceae and Staphylococcus aureus , through the synergistic effect of photodynamic and photothermal effects (Fig.…”
