Abstract Hydrogen energy is an alternative to carbon‐based fuels due its zero pollution and high density. The electrolysis of water, driven by triboelectric nanogenerators (TENGs), considered as a promising green method for hydrogen production. 2D transition metal carbides/nitrides can be used catalyst carriers, through interface engineering prepare molybdenum disulfide/titanium dioxide (MoS 2 /Ti 3 C ) composites accelerating the kinetics evolution reaction (HER). In this work, multilayered rotating TENG (MR‐TENG) designed convert mechanical into electrical constructing self‐powered production system.
