【 摘 要 】

Two key issues regarding the use of clathrates and semiclathrates for practical gas storage and transport is the pressure-temperature stability of the material and very low formation kinetics. For many practical applications, the avoidance of cooling, gas overpressure, and mechanical mixing would be very desirable. Here, we show that biosilica supports from rice husks greatly enhance gases uptake kinetics in tetra-iso-amyl ammonium bromide semiclathrates without introducing complex mixing technologies. These systems show excellent thermal stability and good recyclability.
