Carbon　dioxide　(CO2)　and　hydrogen　sulfide　(H2S)　ordinarily　coexist　in　many　industries,　being　considered　as　harmful　waste　gases.　Simultaneously　converting　CO2　and　H2S　into　syngas　(a　mixture　of　CO　and　H-2)　will　be　a　promising　economic　strategy　for　enhancing　their　recycling　value.　Herein,　a　novel　one-step　conversion　of　CO2　and　H2S　to　syngas　induced　by　non-thermal　plasma　with　the　aid　of　Ni-Mo　sulfide/Al2O3　catalyst　under　ambient　conditions　was　designed.　The　as-synthesized　catalysts　were　characterized　by　using　XRD,　nitrogen　sorption,　UV-vis,　TEM,　SEM,　ICP,　and　XPS　techniques.　Ni-Mo　sulfide/Al2O3　catalysts　with　various　Ni/Mo　molar　ratios　possessed　significantly　improved　catalytic　performances,　compared　to　the　single-component　catalysts.　Based　on　the　modifications　of　the　physical　and　chemical　properties　of　the　Ni-Mo　sulfide/Al2O3　catalysts,　the　variations　in　catalytic　activity　are　carefully　discussed.　In　particular,　among　all　the　catalysts,　the　5Ni-3Mo/Al2O3　catalyst　exhibited　the　best　catalytic　behavior　with　high　CO2　and　H2S　conversion　at　reasonably　low-energy　input　in　non-thermal　plasma.　This　method　provides　an　alternative　route　for　syngas　production　with　added　environmental　and　economic　benefits.
