Herein, we report a composite structure composed of vertically grown molybdenum disulfide (MoS_x) nanosheets supported by conductive carbon nanotube–reduced graphene oxide (CNT–rGO) on Vietnamese traditional paper (MoS_x/CNT–rGO/VTP) for a high-performance electrochemical hydrogen evolution reaction (HER). In the fabrication, CNT–rGO is first prepared on VTP by roll coating, following which the vertically aligned MoS₂ nanosheets are synthesized on the surface of CNT–rGO/VTP through a simple hydrothermal reaction. The catalyst exhibits excellent HER electrocatalytic activity including a low onset potential of 190 mV, Tafel slope of 59 mV dec⁻¹, and excellent stability in an acidic electrolyte solution. The excellent catalytic performance can be attributed to the abundant active edges provided by the vertically aligned MoS_x nanosheets, as well as the effective electron transport provided by the CNT …
