All materials are monoliths with diameters of up to ca. 4.5 cm. The materials are macroscopically homogeneous and porous with surface areas between 170 and 210 m 2/g. The diameter of the TiO 2 nanoparticles (NPs) - mainly anatase with a minor fraction of brookite - and the Au NPs are on the order of 5 and 7-18 nm, respectively. Addition of poly(ethylene oxide) to the reaction mixture enables pore size tuning, thus providing access to different materials with different photocatalytic activities. Water splitting experiments using a sunlight simulator and a Xe lamp show that the new hybrid materials are effective water splitting catalysts and produce up to 30 mmol of hydrogen per 24 h. Overall the article demonstrates that the combination of a renewable and robust scaffold such as B. mori silk with a photoactive material provides a promising approach to new monolithic photocatalysts that can easily be recycled and show great potential for application in lightweight devices for green fuel production. 2018 18 Postprints der Universität Potsdam Mathematisch-Naturwissenschaftliche Reihe 581 urn:nbn:de:kobv:517-opus4-423499 10.25932/publishup-42349 Mathematisch-Naturwissenschaftliche Fakultät OPUS4-41731 misc Abouserie, Ahed; Schilde, Uwe; Taubert, Andreas The crystal structure of N-butylpyridinium bis(μ2-dichlorido)-tetrachloridodicopper(II), C₁₈H₂₈N₂Cu₂Cl₆ C₉H₁₄Cl₃CuN, monoclinic, P2₁/n (no. 14), a = 9.6625(6) Å, b = 9.3486(3) Å, c = 14.1168(8) Å, β = 102.288(5)°, V = 1245.97(11) ų, Z = 4, Rgₜ(F) = 0.0182, wRᵣₑf(F²) = 0.0499, T = 210(2) K. 2018 4 Zeitschrift für Kristallographie - New Crystal Structures urn:nbn:de:kobv:517-opus4-417310 Mathematisch-Naturwissenschaftliche Fakultät
