Bio-based porous materials for hydrogen storage and environmental applications

BIOPOROMAT

The project addresses an innovative and multidisciplinary idea that can open up further advances in the field of high-tech bio-based products, wastes conversion, porous materials, alternative energy storage, environmental remediation and sustainable design. This project aims to valorise a bio-based active rich carbon by-product, resulted as a solid phase from thermochemical conversion of biomass wastes, into an unprecedented polymeric cryogel with tailored porosity. The porosity and geometry of the new bio-based material can be controlled within broad limits of the experimental parameters specific to each stage and according with targeted applications. The research activities proposed in the project, also involve extensive testing and applications of the achieved composites in two high interest current trends: (i) in the fields of clean/renewable energy sources for hydrogen storage and (ii) in reducing the environmental impact (promising substrate in wastewater/gas streams purification). All the research will be conducted using the latest state of the art analytical tools, jointly agreed standard procedures and specific investigation and characterization tools (TGA, FT-IR, XPS, DLS, BET, SEM/TEM and AFM). The proposal goal is timely and in line with two important in progress EU initiatives: Bio Based Industries Joint Undertaking (bbi.europa.eu) and Hydrogen Europe (hydrogeneurope.eu).

Project concept

Summary of the activities carried out in the framework of this project:

The purpose of this project was to design and obtain hybrid materials based on carbon micro/nano structures (CMNS), resulting from the conversion of biomass waste, embedded in polymer matrices (natural or synthetic), with environmental and energy storage applications.

A summary of the main results obtained is presented beneath.

O1 focused on the evaluation and analysis of the availability and types of biomass waste, through the chemical, morphological and structural characterization of some lignocellulosic waste in order to achieve a realistic evaluation of the valorization potential as well as the establishment of their pretreatment and conversion techniques. The biomass wastes (spruce bark, vine wood and wheat straw, the necessary pretreatments (physical) as well as the thermochemical conversion techniques (slow pyrolysis at 550°C and hydrothermolysis at 260°C) were defined and their optimized protocols have been developed. CMNS have been extensively investigated.

O2 aimed at porosity tailoring for the obtained CMNS. Obtaining data through numerous experimental tests and evaluations, the activities resulted in the validation of three working protocols for the adaptation of the porosity/functionalization of the CMNS in direct correlation with the targeted applications. Two types of polymer gels were designed as matrices for embedding CMNS: (i) a hydrogel based on a natural polymer (gellan); (ii) a cryogel based on Poly(2-hydroxyethyl methacrylate) (p-HEMA) and one based on poly-acrylic alcohol (PAA) physically cross-linked with poly-vinyl alcohol (PVA), where carbon structures were embedded successfully; (iii) two configurations of hybrid materials based on CMNS functionalized for energy storage and bacterial immobilization (bioremediation) applications.

O3: The carried-out studies showed that the gels based on gellan and CMNS present an affinity for dyes (Crystal Violet and Methylene Blue) with better adsorption capacities at equilibrium than other gels reported in the literature. Also, removal rates of 70-97% were obtained for Pb(II) ions and emerging organic pollutants (diclofenac). One of the proposed configurations represents a remarkable protective support for bacterial immobilization that increases by 4 times the survival rate of Pseudomonas bacteria, and by 30% the bioremediation capacity of wastewater polluted with plasticizer agents (diethyl phthalate). In the alternative forms of energy storage, the supercapacitor characteristics of the hybrid carbon material were validated, as well as the ability to retain some gases (H2, N2, CO2) of the hybrid cryogels obtained within the project. Some of the proposed composite configurations could represent a good protective film for H2 storage containers, reducing the possibility of embrittlement of the metal ferrule.
