Water is essential resource for the earthecosystems. Nevertheless, current waterremediation technologies fail to remove theuncountable types of anthropogenic persistencechemicals. Therefore, the development of efficientand broadly applicable water remediationtechnology is an urgent need.Of the current wastewater treatment technologies,adsorption and photocatalysis have emerged asgreen, efficient, selective and reusable options. Toachieve broad-scope adsorbents orphotocatalysts, the materials should combinemicro-, meso- and macro-porosity, chemicalfunctionalibility and effective photo-degradationmechanisms driven within the sorbent matrix.Encompassing these characteristics in a singlematerial usually requires from the engineering ofcomposites. Therefore, we have combined amacro- and mesoporous Chitin (CH) biopolymerwith microporous Metal-Organic Frameworks(MOF) sorbents and photocatalysts, to createcomposites with multiple porosities and chemicalfunctionalities. Chitin (CH) macro- and meso-porous gels can be used as sorbents formacromolecules and nanoparticles, whilst MOF-808 and MIL-125 are microporous photocatalystsable to capture and degrade molecules of smallersizes.
