Multishelled CuO/Cu2O induced fast photo-vapour generation for drinking water

Mind the Interface Gap: Exposing Hidden Interface Defects at the Epitaxial Heterostructure between CuO and Cu2O

“…Cuprous (Cu 2 O) and cupric (CuO) oxide are among the candidates that meet many of these necessary requirements while offering potentially promising performance in terms of photocurrent and photovoltage output. , They are also gaining increased attention in the field of battery electrodes, photonic crystals, hydrogen production, water treatment, and even antibacterial activity . However, low absorption and poor chemical stability in aqueous conditions combined with fast electron–hole recombination hinder the onset of photocurrent and limit the practical utilization of Cu 2 O or CuO. , For example, in order to efficiently absorb sunlight, Cu 2 O films must typically be at least 1 μm thick.…”

Freestanding Hydrophilic/Hydrophobic Janus Covalent Organic Framework Membranes for Highly Efficient Solar Steam Generation

“…Ideal solar thermal materials should simultaneously possess a broad and strong absorption capacity of the solar spectrum, efficient conversion of solar energy to heat energy, low heat dissipation and energy loss, and constant supply of water, as well as effective escape of steam. 15−17 Currently, solar thermal materials mainly include those based on carbons, 16,18 metals and metal oxides, 19,20 MXenes, 21,22 polymers, 23−27 and those installed with photoresponsive groups (porphyrin, 28,29 azobenzene, 30−32 and radical 33,34 ). Exploring new solar thermal materials for solar steam generation is of great significance and in high demand.…”

“…Bulk water is continuously pumped up to the hot surface via water pathways through capillary force, and evaporation occurs in the localized high-temperature region. − The key of this innovative technology to achieve a high water evaporation rate and solar thermal conversion efficiency mainly relies on solar thermal materials.
