摘要： Process for preparing a porous monolith comprising between 10% and 100% by weight of a semiconductor relative to the total weight of the porous monolith, which process comprises the following steps: a) a first aqueous suspension containing polymer particles is prepared; b) a second aqueous suspension containing particles of least one inorganic semiconductor is prepared; c) the two aqueous suspensions prepared in steps a) and b) are mixed in order to obtain a paste; d) a heat treatment of the paste obtained in step c) is carried out in order to obtain the monolith with multimodal porosity.

摘要： The invention relates to a porous monolith comprising between 20 wt.-% and 70 wt.-% TiO 2 relative to the total weight of the monolith, and between 30 wt.-% and 80 wt.-% a refractory oxide, selected from silica, alumina or silica-alumina, relative to the total weight of the monolith, characterized in that said porous monolith has a bulk density of less than 0.19 g/mL.
