AB  - The design of cost-efficient earth-abundant catalysts with superior performance 
      for the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is 
      extremely important for future renewable energy production. Herein, we report a 
      facile strategy for constructing Ni nanotube arrays (NTAs) on a Ni foam (NF) 
      substrate through cathodic deposition of NiCu alloy followed by anodic stripping 
      of metallic Cu. Based on Ni NTAs, the as-prepared NiSe2 NTA electrode by NiSe2 
      electrodeposition and the NiFeOx NTA electrode by dipping in Fe3+ solution 
      exhibit excellent HER and OER performance in alkaline conditions. In these 
      systems, Ni NTAs act as a binder-free multifunctional inner layer to support the 
      electrocatalysts, offer a large specific surface area and serve as a fast 
      electron transport pathway. Moreover, an alkaline electrolyzer has been 
      constructed using NiFeOx NTAs as the anode and NiSe2 NTAs as the cathode, which 
      only demands a cell voltage of 1.78 V to deliver a water-splitting current 
      density of 500 mA cm-2, and demonstrates remarkable stability during long-term 
      electrolysis. This work provides an attractive method for the design and 
      fabrication of nanotube array-based catalyst electrodes for highly efficient 
      water-splitting.
