Boosting carbonate radicals production to enhance photocatalytic Degradation of micropollutants.

Reversing the detrimental effects of complex water matrices (e.g., HCO) on micropollutant degradation through modulation of the reaction pathway remains a major challenge.

Rapid self-assembled electroactive biohybrid cathode-driven electron transfer for enhanced uranium bioremediation.

Efficient and eco-friendly purification of uranium-bearing wastewater is essential for the safety of the water ecosystem and sustainable development of the nuclear energy industry. Although bioelectrochemical systems show great prospect for uranium bioremediation, the uranium removal efficiency is often limited by the ineffective quality of biofilm formation and unsatisfactory electron transfer. Here we propose a rapid self-assembled biofilm formation strategy to construct a sulfate-reducing bacteria-carbon cloth biohybrid cathode (CF-PQ7) modified with cotton-derived carbon fibers for the simultaneous removal of uranium and sulfate.

Data-Driven Accelerated Discovery Coupled with Precise Synthesis of Single-Atom Catalysts for Robust and Efficient Water Purification.

The development of advanced catalysts frequently employs trial-and-error methods and is lack of highly controlled synthesis, resulting in unsatisfactory development efficiency and performance. Here we propose a data-driven prediction coupled with precise synthesis strategy to accelerate the development of single-atom catalysts (SACs) for efficient water purification. The data-driven approach enables the rapid screening and prediction of high-performance SACs from 43 metals-N structures comprising transition and main group metal elements, followed by validation and structural modulation for improved performance through a highly controllable hard-template method.

Modulation of ultrathin nanosheet structure and nitrogen defects in graphitic carbon nitride for efficient photocatalytic bacterial inactivation.

The efficient generation and utilization of ROSs is a key step in determining the achievement of safe drinking water by photocatalytic bacterial inactivation technology. Although graphitic carbon nitride (g-CN) serves as a green and promising photocatalyst for water disinfection, insufficient bacterial capturing capacity and serious charge recombination of pristine g-CN extremely restrict its bactericidal activity. Herein, we develop a facile thermal exfoliation and thermal polymerization method to prepare the nitrogen-defective ultrathin g-CN nanosheets (DUCN-500).
