What a natural harmony! From birth to death, each species has its own life cycle and innate mechanisms decoded and to be decoded by scientists. The destiny of life cycle can be revealed by genome within a cell as the core of living beings. The more scientific discoveries about the core, the higher possibilities to disclose the truth of life. For sustainable development of our planet, it is important to build up one co-existing ecosystem for all living things.|

Ammonia is an essential resource across modern industry and agriculture. Direct nitrogen reduction reaction (NRR) using electrolysis provides a renewable and distributed route for manufacturing NH3. Considerable effort has been devoted to the design and development of advanced and robust electrocatalysts to enhance the efficiency of NRR. We report a synergistic protocol to boost electrocatalytic ammonia production by jointly tuning the Te vacancies (VTe) and surface hydrophobicity of two-dimensional TaTe2. Remarkable NH3 faradic efficiency of up to 32.2% is achieved at a mild overpotential, which is largely maintained even after 100.0 h of continuous operation. We identify that the edge plane of TaTe2 and VTe serve as the main active sites for NRR and the potential-determining step is ∗NH2 + (H+ + e¨C) ¡ú NH3.
