Figure S1: Scheme of the thermobalance used for pyrolysis, created by the Laboratoire Thermique Energétique et Procédés de l’Université de Pau et des Pays de l’Adour (LaTEP, UPPA); Figure S2: Infrared spectra of RH2-SiO2 (from AWRH2) and commercial amorphous silica measured by FTIR-ATR; Figure S3: RH2-SiO2-2 (left) nitrogen adsorption/desorption isotherm at 77K and (right) its t-plot curve. Figure S4: Pore size distributions characterized by mercury intrusion porosimetry for (a) RH1-SiO2, (b) RH2-SiO2, and (c) RH3-SiO2; Figure S5: STEM-HAADF images of RH2-SiO2 particles and Cd crystals attached onto the silica and the respective EDX spectra of both sites; Figure S6: AFM images obtained by tapping method in 3D of (a1) RH2-SiO2 before adsorption and (a2) RH2-SiO2-Cd, in 2D of (b1) RH2-SiO2 before adsorption and (b2) RH2-SiO2-Cd, and phase image and section image of (c1) RH2-SiO2 before adsorption and (c2) RH2-SiO2-Cd; Table S1: Assigned compounds by GC-MS analysis of the bio-oil sample from AWRH and RH; Table S2: Elemental composition of RH2-SiO2-Cd obtained from EDX analysis of 4 selected sites. Percentages have been corrected, removing Ni percentage, which comes from the coating.
