AI Technical Summary
In the existing technology, ionic covalent organic nanomaterials have poor hydrophilicity in the field of photocatalytic hydrogen evolution, resulting in insufficient catalytic performance, and there is a lack of highly efficient photocatalysts that can be prepared by one-pot method.
Ionic covalent organic nanomaterials were prepared by Knoevenagel condensation reaction. N-ethyl-2,4,6-trimethylpyridinium bromide and other raw materials were used to form nanomaterials with strong conjugated structures to avoid crystal loss. The combination of co-catalyst, sacrificial electron donor and dispersant was optimized to improve hydrophilicity and photocatalytic performance.
It achieves high efficiency in photocatalytic hydrogen evolution performance and chemical stability. The design of ultrathin nanosheets exposes active sites, and the photocatalytic hydrogen production rate and efficiency are improved under optimized conditions.
