Construction of nanomaterial and integrated catalyst based on biological template: a review

doi:10.11949/0438-1157.20230456

Abstract

Abstract:

The design, preparation and application of new nano-catalytic materials are one of the research hotspots in the field of catalysis in recent years. Biological templates with complex and fine hierarchically porous structures are ubiquitous and can be used as soft templates, hard templates, or support to prepare nanomaterials with highly connective and hierarchical pores. Based on the regulation of preparation process parameters, the macro-morphology and micro-nano structure of the biological templates could be retained, as well as replacing the original biological components with the required catalytic components (e.g., metals, metal oxides, zeolites, etc.). This strategy provides new ideas for the design of nanomaterial and integrated nanocatalysts. In particularly, the “multi-level space” of such integrated catalytic materials is very difficult to be prepared by the existing traditional methods or the preparation process would be cumbersome in most cases. Starting from several typical biological templates from different sources, this review introduces the common preparation methods of nanomaterials and integrated nanocatalysts using natural biological templates, summarizes the research status of such integrated materials in catalysis, and looks forward to future research works on the utilization of biological templates to fabricate integrated nanocatalysts with multi-components.

Key words: biological template, nanomaterial, integrated catalyst, assembly, hierarchical pore

摘要：

新型纳米催化材料的设计、制备与应用是近年来催化领域的研究热点之一。具有复杂精细分级结构的生物模板在自然界中普遍存在，可作为软模板、硬模板或载体制备高连通性多级孔纳米材料，且通过制备条件参数的调控，其既能保留生物模板的宏观形貌和微纳结构，又能将生物模板原先的化学组成置换或负载所需催化组分（金属、金属氧化物、分子筛等），为纳米材料和集成催化剂的设计提供了新思路。而该类集成催化材料的“多层次空间结构”是现有制备技术很难获得的或者所需制备流程相对烦琐。本文从几种不同来源的典型生物模板出发，介绍了基于生物模板构建纳米材料及集成催化剂的方法，总结了该类集成纳米材料在催化领域的研究现状与应用实例，并对未来采用生物模板制备多化学组成的集成催化剂进行了展望。
