The catalytic decomposition of hydrogen iodide in a membrane reactor using silica membranes derived from hexyltrimethoxysilane (HTMOS) was investigated for the production of hydrogen in the thermochemical water splitting iodine-sulfur process. The silica membranes were prepared by counter-diffusion chemical vapor deposition using porous alumina support tubes in both the absence and presence of a -alumina layer. The silica membranes formed on -alumina-coated -alumina tubes displayed a higher H $_{2}$ permeance than that formed directly on an -alumina tube. A silica membrane based on a 1.5 m-thick -alumina layer fabricated under deposition conditions of 450 $^{circ}$ C, 1200 s, and a N $_{2}$ carrier gas velocity of 0.044 m s $^{-1}$ exhibited a high H $_{2}$ permeance of 9.4 10 $^{-7}$ mol Pa $^{-1}$ m $^{-2}$ s $^{-1}$ while maintaining an H $_{2}$ /N $_{2}$ selectivity of over 80.0. The performance of a membrane reactor based on an HTMOS-derived silica membrane was evaluated at 400 $^{circ}$ C by measuring the HI conversion and H $_{2}$ flow rates. The conversion was approximately 0.48 when the HI flow rate was 9.7 mL min $^{-1}$ .

The thermal decomposition of hydrogen iodide (HI) to produce hydrogen in a membrane reactor was investigated using the separation characteristics of a silica membrane with the aim of improving the one-pass decomposition rate of HI decomposition reaction in the thermochemical IS process. The silica membranes were prepared by a counter diffusion chemical vapor deposition (CVD) of hexyltrimethoxysilane (HTMOS) using alumina porous support. The membrane reactor phenomenon was evaluated using determined H $_{2}$ production rate from HI decomposition at 400 $^{circ}$ C. It was found from experiments that produced H $_{2}$ rate was approximately 1.5 mL min $^{-1}$ in permeated site. Hydrogen was successfully produced and extracted from the HI decomposition membrane reactor with a utilization of the HTMOS silica membrane. The HTMOS silica membrane was effective for the HI decomposition at higher reaction temperature of 400 $^{circ}$ C in the membrane reactor.
