Electrocatalytic　hydrogen　production　is　an　effective　way　to　produce　hydrogen　energy,　and　the　key　is　to　find　inexpensive　and　effective　catalysts.　Loading　transition　metal　sulfides　onto　two-dimensional　transition　metal　carbide　(MXene)　is　an　effective　method　to　prepare　cheap　and　high-performance　hydrogen　evolution　reaction　(HER)　catalysts.　In　this　study,　Mo2TiAlC2　was　etched　with　hydrofluoric　acid　to　prepare　Mo2TiC2Tx　MXene,　which　was　then　composited　with　MoS2　and　CoS2　to　prepare　defect-rich　MoS2/CoS2@Mo2TiC2Tx　composite　by　a　hydrothermal　method.　MoS2/CoS2　provides　a　large　number　of　active　sites　for　electrocatalysis,　while　Mo2TiC2Tx　MXene　as　a　carrier　not　only　provides　nucleation　and　growth　sites　for　MoS2/CoS2,　but　also　increases　the　rate　of　electron　transfer　in　HER　process,　which　achieves　good　synergy　between　MoS2/CoS2　and　Mo2TiC2Tx　MXene.　Consequently,　MoS2/CoS2-2@Mo2TiC2Tx　exhibits　an　excellent　HER　performance.　When　the　current　density　reaches　10　mA　cm-2,　the　optimal　MoS2/CoS2-2@Mo2TiC2Tx　catalyst　only　requires　an　overpotential　of　80　mV,　and　exhibits　good　cycling　stability　and　durability.　This　work　gives　a　new　idea　for　the　preparation　of　efficient　HER　catalysts　using　non-precious　metal　composites　to　replace　the　precious　Pt/C.
