Abstract

Intelligentization of materials and structures is an important trend. Herein, the stimuli-responsive 4D aerogel is used as a smart substrate for rapid reduction in tetracycline (TC) pollution, in which this smart stimuli-responsive substrate is designated as P4D. Its fourth dimension originates from stimuli-responsive characteristics with time evolution. Meanwhile, the covalent organic frameworks (COFs) composite is constructed by BiPO and triazine-based sp carbon-conjugated g-CN-COF (COF-1), which is another key aspect of COF-1/BiPO@P4D for rapid photocatalytic degradation regarding TC pollution. This emerging smart structure of COFs@P4D can fix programmable temporary state and recover permanent state under thermal or water stimulus without any complicated equipment. Its performance can be tailored by structure, composition, and function. Compared with traditional powder-form photocatalysts, this stimuli-responsive structure provides attractive advantages, such as high permeable framework, self-adaptivity, flexibly customized functional groups, and fast reduction in TC pollution. The predictable development of COFs@P4D could draw much attention for various promising applications in pollution treatment and sensors.

摘要

材料与结构的智能化是一个重要趋势。在此，刺激响应型4D气凝胶被用作快速降低四环素（TC）污染的智能基底，这种智能刺激响应型基底被命名为P4D。其第四维源于随时间演变的刺激响应特性。同时，通过BiPO和基于三嗪的sp碳共轭g-CN-COF（COF-1）构建共价有机框架（COF）复合材料，这是COF-1/BiPO@P4D快速光催化降解TC污染的另一个关键方面。这种新兴的COFs@P4D智能结构可以在热或水刺激下固定可编程的临时状态并恢复永久状态，无需任何复杂设备。其性能可通过结构、组成和功能进行定制。与传统粉末状光催化剂相比，这种刺激响应结构具有吸引人的优势，如高渗透性框架、自适应性、可灵活定制的官能团以及快速降低TC污染。COFs@P4D的可预测发展可能会在污染治理和传感器等各种有前景的应用中引起广泛关注。
