What is it about?
Salinity anions are the key factors affecting the reactivity and efficiency in wastewater purification. The exciting discovery is that the interaction between salinity anions and surface DRC can mediate the distortion of local hydrogen bond networks of H2O molecules, which triggers pollutants to break through restrictions and quickly provide electrons, achieving high-efficiency and low-consumption water self-purification under ambient conditions. Salinity is no longer a harmful factor in the process of water purification, on the contrary, it becomes a favorable channel for rapid electron transfer. This work has enlightenment for the environment, energy, materials and chemical industry by distorting the hydrogen bond networks strategy to accelerate the reaction efficiency.

Why is it important?
This work addresses the bottleneck of resource and energy consumption in high salinity wastewater treatment and provides important guidance for applying the proposed water self-purification system to environmental remediation and even fine chemical industry.
Perspectives
I hope that this discovery can be effectively applied to the treatment of saline wastewater and lead the development of water treatment technology.
