CO_x hydrogenation to methanol and other hydrocarbons under mild conditions with Mo₃S₄@ZSM-5.

ABSTRACT: The hydrogenation of CO₂ or CO to single organic product has received widespread attentions. Here we show a highly efficient and selective catalyst, Mo₃S₄@ions-ZSM-5, with molybdenum sulfide clusters ([Mo₃S₄]ⁿ⁺) confined in zeolitic cages of ZSM-5 molecular sieve for the reactions. Using continuous fixed bed reactor, for CO₂ hydrogenation to methanol, the catalyst Mo₃S₄@NaZSM-5 shows methanol selectivity larger than 98% at 10.2% of carbon dioxide conversion at 180 °C and maintains the catalytic performance without any degeneration during continuous reaction of 1000 h. For CO hydrogenation, the catalyst Mo₃S₄@HZSM-5 exhibits a selectivity to C₂ and C₃
