High-temperature solar steam generation by MWCNT-HfTe
Although recent studies have shown high-temperature solar steam generation, their solar-to-steam conversion efficiency is limited (25%) owing to higher heat losses at elevated temperatures (>100 °C) [30], [31]. Furthermore, the use of photothermal generated steam for sterilization purposes has been investigated by researchers [32], [33], [34].
