Title: Plant polyphenol-derived multicomponent mesoporous colloidal spheres for sensing and electrocatalysis applications
Abstract: 
Mesoporous colloidal spheres have attracted increasing attentions due to their high specific surface area, large pore size, tunable compositions as well as broad applications in separation, catalysis, sensing and energy. The sustainable and scalable synthesis of mesoporous colloidal spheres with tailor-made properties and functions is desirable but challenging. Polyphenols are ubiquitous secondary metabolites of plant, which is one of sustainable and renewable building blocks for functional nanomaterials. Recently, we develop a controllable sol-gel strategy for the synthesis of metal-phenolic coordination polymer spheres with tunable mono-, bi-, tri- and penta-metal species using plant polyphenol as a ligand (Figure 1).[1] Such coordination spheres can be used as a versatile precursor for synthesis of mesoporous metal/carbon composites (such as Fe/Co-N-C) and multicomponent metal oxide spheres with tunable compositions and unique properties, which exhibited excellent performance in gas sensing and electrocatalysis.
