Direct decomposition of H2S into H-2 and S is an alluring prospect because COx-free H-2 and S can be simultaneously recovered from an abundant and toxic waste gas. However, it is still a great challenge to achieve H2S decomposition reaction with high efficiency, due to the thermal equilibrium limitation in this reaction. Herein, we develop Core-Shell Mo2N-MoC@SiO2 via in situ formation, as a novel microwave catalyst for highly effective direct decomposition of H2S into COx-free H-2 and S by microwave catalysis. Importantly, the H2S conversion is impressively up to 96.5 % at 750 degrees C over Mo2N-MoC@SiO2 under microwave irradiation, which greatly surpass the corresponding H2S equilibrium conversion. Moreover, Mo2N-MoC@SiO2 exhibits excellent stability under microwave irradiation. This work provides an alternative avenue for the high value utilization of H2S resources and thus opens a new avenue for the design of high active and stable microwave catalysts in microwave catalytic reactions.
