Abstract:
1. A method for the synthesis of a mesoporous lithium transition metal compound by a liquid crystal templating method, the method comprising the steps of (i) reacting a lithium salt with one or more transition metal salts in the presence of a surfactant, the surfactant being present in an amount sufficient to form a liquid crystal phase in the reaction mixture (ii) heating the reaction mixture so as to form a sol-gel and (iii) removing the surfactant to leave a mesoporous product, wherein the surfactant concentration in the reaction mixture lies in the range of 40-60 wt %, and wherein a lyotropic liquid crystal phase is formed in the reaction mixture and maintained through steps (i) and (ii) by controlling the reaction conditions to prevent destabilisation thereof.
