AB  - With the development of clean hydrogen energy, the cost effective and 
      high-performance hydrogen evolution reaction (HER) electrocatalysts are urgently 
      required. Herein, a green, facile, and time-efficient Ru doping synergistic with 
      air-plasma treatment strategy is reported to boost the HER performance of 
      CoNi-layered double hydroxide (LDH) nanotube arrays (NTAs) derived from zeolitic 
      imidazolate framework nanorods. The Ru doping and air-plasma treatment not only 
      regulate the oxygen vacancy to optimize the electron structure but also increase 
      the surface roughness to improve the hydrophilicity and hydrogen spillover 
      efficiency. Therefore, the air plasma treated Ru doped CoNi-LDH (P-Ru-CoNi-LDH) 
      nanotube arrays display superior HER performance with an overpotential of 29 mV 
      at a current density of 10 mA cm(-2) . Furthermore, by assembling P-Ru-CoNi-LDH 
      as both cathode and anode for two-electrode urea-assisted water electrolysis, a 
      small cell voltage of 1.36 V is needed at 10 mA cm(-2) and can last for 100 h 
      without any obvious activity attenuation that showing outstanding durability. In 
      general, the P-Ru-CoNi-LDH can improve the HER performance from intrinsic 
      electronic structure regulation cooperated with extrinsic surface wettability 
      modification. These findings provide an effective intrinsic and extrinsic 
      synergistic effect avenue to develop high performance HER electrocatalysts, which 
      is potential to be applied to other research fields.
