摘要:
The invention relates to a method for manufacturing macroscopic fibres of titanium dioxide (ΤiO 2 ) by continuous extrusion in a one-way flow, to the macroscopic fibres of ΤiO 2 that can be obtained by such a method, to the use of said fibres in heterogeneous photocatalysis for decontamination of organic pollutants from gaseous environments, and to a method for decontaminating gaseous environments, in particular air, using such fibres.
摘要:
The present invention relates to a porous electrochemical electrode made up of a solid cellular material provided in the form of a semi-graphitised carbon monolith comprising a hierarchised porous network free of mesopores and including macropores with a mean dimension d A of 1 μm to 100 μm, and micropores with a mean dimension d I of 0.5 nm to 2 nm, said macropores and micropores being interconnected. In said electrode, the macropores contain at least one electroactive species in direct contact with the semi-graphitised carbon that makes up the surface of the macropores. The invention also relates to a method for preparing such an electrode as well as to the use thereof as a biosensor or for manufacturing a biopile.
摘要:
The invention relates to a process for preparing an inorganic material that is in the form of a cellular monolith constituted of a silica matrix comprising interconnected macropores, said process comprising at least one step of mineralization of an oil-in-water emulsion formed of droplets of an oily phase dispersed in a continuous aqueous phase and in which colloidal solid particles are present at the interface formed between the continuous aqueous phase and the dispersed oily phase droplets. The invention also relates to the various uses of the material obtained according to this process, in particular for separation chemistry and filtration, carrying out chemical reactions that are catalyzed in the heterogeneous phase, as thermal or sound insulation material, or even as a template for manufacturing carbon-based backbones with controlled porosity.
